Irrationality of the dilogarithm at reciprocals of integers

Ruiyi Zhang Independent Researcher, Columbia, Maryland, USA
Abstract.

We prove that Li2⁡(1/n)\operatorname{Li}_{2}(1/n) is irrational for every nonzero integer nn. The proof combines a determinant criterion with exact fixed-base integerization, logarithmic-potential estimates, Frobenius nonvanishing, and a three-form Hermite–Padé construction. The finite positive range is treated by a common variational problem and two endpoint certificates; the negative middle range is handled by signed contour integrals at the six bases −2,…,−7-2,\ldots,-7; the two remaining tails follow from an explicit Hermite–Padé estimate. Every numerical constant used in the argument is given as a rational bound or an explicitly directed interval.

1. Introduction

For an integer ss with |s|≥2|s|\geq 2, irrationality of Li2⁡(1/s)\operatorname{Li}_{2}(1/s) was proved by Hata [5] for all s≤−5s\leq-5 and s≥7s\geq 7, and by Rhin and Viola [11] for s=6s=6. A recent preprint of Prellberg [10] treats s=−4,−3s=-4,-3 and 55. These works are cited for history only: no irrationality statement from them is used below, and the proof is self-contained. The cases s=−2,2,3,4s=-2,2,3,4 were open; among them is Li2⁡(1/2)=π2/12−(log⁡2)2/2\operatorname{Li}_{2}(1/2)=\pi^{2}/12-(\log 2)^{2}/2. For s=±1s=\pm 1 the values are rational multiples of π2\pi^{2}, which is irrational [8].

The general tools are the prime number theorem [2]; Kummer’s carry theorem [7] and Lucas’ congruence [9]; the Cauchy–Binet formula [4] and its integral form due to Andréief [1, 3]; Cauchy’s double-alternant determinant  [6]; logarithmic potential theory [12]; and Stirling’s formula [13].

We call the positive determinant P0 and the signed contour determinant V. These names refer to the two explicit constructions below.

The endpoint energy lower bounds and fixed-base field bounds are computer-assisted: directed interval arithmetic verifies them from the printed tables, with the algorithm and code supplied in the ancillary files.

The proof applies the criterion below to one defined determinant at a time. Sections 5–6 treat positive bases; Sections 9–10 treat the negative bases; Section 12 treats both tails, and Section 11 supplies eventual nonvanishing sequences. The final assembly checks the ranges and their boundary points.

2. Main theorem

For |z|≤1|z|\leq 1, put

Li2⁡(z)=∑r≥1zrr2.\operatorname{Li}_{2}(z)=\sum_{r\geq 1}\frac{z^{r}}{r^{2}}.
Theorem 2.1.

For every nonzero integer nn, the number Li2⁡(1/n)\operatorname{Li}_{2}(1/n) is irrational.

For n=1n=1 and n=−1n=-1 this follows from Li2⁡(1)=π2/6\operatorname{Li}_{2}(1)=\pi^{2}/6 and Li2⁡(−1)=−π2/12\operatorname{Li}_{2}(-1)=-\pi^{2}/12, together with the irrationality of π2\pi^{2} [8]; the determinant argument covers all |n|≥2|n|\geq 2.

2.1. Coverage map

The ranges below are disjoint and cover all remaining nonzero integers.

base range construction ingredients
±1\pm 1 classical evaluations π2\pi^{2}
2≤a≤112\leq a\leq 11 positive determinant arithmetic, energy, nonvanishing
−7≤a≤−2-7\leq a\leq-2 signed determinant arithmetic, contour energy, nonvanishing
a≥12a\geq 12 or a≤−8a\leq-8 three-form Hermite–Padé residues, integerization, saddle estimates

In each application of the criterion, the determinant, integerizer, analytic estimate, and nonvanishing sequence belong to the same polynomial family at the indicated base.

3. The determinant criterion

Let (mk)k≥1(m_{k})_{k\geq 1} be a strictly increasing sequence of positive integers, and let Gmk,a⁢(T)∈ℚ⁢[T]G_{m_{k},a}(T)\in\mathbb{Q}[T] have degree at most mkm_{k}. Suppose that, for every fixed integer aa under consideration, there are positive rational numbers Dmk,aD_{m_{k},a} and a fixed real target tt such that

(3.1) Dmk,a⁢Gmk,a⁢(T)\displaystyle D_{m_{k},a}G_{m_{k},a}(T) ∈ℤ⁢[T],\displaystyle\in\mathbb{Z}[T], lim supk→∞mk−2⁢log⁡Dmk,a\displaystyle\limsup_{k\to\infty}m_{k}^{-2}\log D_{m_{k},a} ≤τ⁢(a),\displaystyle\leq\tau(a),
(3.2) log⁡|Gmk,a⁢(t)|\displaystyle\log|G_{m_{k},a}(t)| ≤−α⁢(a)⁢mk2+O⁢(mk⁢log⁡mk),\displaystyle\leq-\alpha(a)m_{k}^{2}+O(m_{k}\log m_{k}),

and, for every rational ξ\xi, there is k0=k0⁢(a,ξ)k_{0}=k_{0}(a,\xi) such that

Gmk,a⁢(ξ)≠0(k≥k0).G_{m_{k},a}(\xi)\neq 0\qquad(k\geq k_{0}).

If α⁢(a)>τ⁢(a)\alpha(a)>\tau(a), then tt is irrational.

Indeed, if t=ξ=u/v∈ℚt=\xi=u/v\in\mathbb{Q} in lowest terms, then for every sufficiently large kk, vmk⁢Dmk,a⁢Gmk,a⁢(ξ)v^{m_{k}}D_{m_{k},a}G_{m_{k},a}(\xi) is a nonzero integer, while (3.1) and (3.2) make its absolute value tend to zero. The determinant, integerizer and nonvanishing statements must refer to the same polynomial.

4. Positive determinant

For g=m/2g=m/2, let Im={m/4,…,5⁢m/4−1}I_{m}=\{m/4,\ldots,5m/4-1\} and Jm={0,…,2⁢m−1}J_{m}=\{0,\ldots,2m-1\}. Set

Ui⁢(a)=ai⁢(i+gg),ti⁢(a)=∑r=1iUi−r⁢(a)r+ai⁢∑s=1g(−1)s−1s⁢(i+gg−s)⁢((aa−1)s−1).U_{i}(a)=a^{i}\binom{i+g}{g},\quad t_{i}(a)=\sum_{r=1}^{i}\frac{U_{i-r}(a)}{r}% +a^{i}\sum_{s=1}^{g}\frac{(-1)^{s-1}}{s}\binom{i+g}{g-s}\left(\left(\frac{a}{a% -1}\right)^{s}-1\right).

For i≠ji\neq j, define

Ci⁢j⁢(a)=Ui⁢(a)−Uj⁢(a)j−i,Bi⁢j⁢(a)=ti⁢(a)−tj⁢(a)j−i,C_{ij}(a)=\frac{U_{i}(a)-U_{j}(a)}{j-i},\qquad B_{ij}(a)=\frac{t_{i}(a)-t_{j}(% a)}{j-i},

and put Ai⁢j⁢(a)=0A_{ij}(a)=0. On the diagonal,

Ai⁢i⁢(a)=Ui⁢(a),Ci⁢i⁢(a)=−Ui⁢(a)⁢∑s=1g1i+s,A_{ii}(a)=U_{i}(a),\quad C_{ii}(a)=-U_{i}(a)\sum_{s=1}^{g}\frac{1}{i+s},
Bi⁢i⁢(a)=∑r=1iUi−r⁢(a)r2−ai⁢∑s=2g(−1)ss⁢(i+gg−s)⁢∑r=1s−1(a/(a−1))r−1r.B_{ii}(a)=\sum_{r=1}^{i}\frac{U_{i-r}(a)}{r^{2}}-a^{i}\sum_{s=2}^{g}\frac{(-1)% ^{s}}{s}\binom{i+g}{g-s}\sum_{r=1}^{s-1}\frac{(a/(a-1))^{r}-1}{r}.

The P0 determinant is

(4.1) Gm,a⁢(T)=det[C⁢(a)Im,JmB⁢(a)Im,Jm−T⁢A⁢(a)Im,Jm].G_{m,a}(T)=\det\begin{bmatrix}C(a)_{I_{m},J_{m}}\\ B(a)_{I_{m},J_{m}}-TA(a)_{I_{m},J_{m}}\end{bmatrix}.

5. Arithmetic for the positive determinant

This section proves the fixed-base denominator estimate for the P0 pencil. The base is fixed before the limit in mm is taken. No estimate uniform in unbounded |a||a| at finite mm is asserted. The proof has an algebraic part, an exact sum over primes, and a prime-number-theorem limit. The algebraic and limiting arguments below are all-mm arguments. The large-ratio contribution is specified by the rational table 5.1 and its type-generation rule.

Write m=4⁢hm=4h, g=2⁢hg=2h, I={h,…,5⁢h−1}I=\{h,\ldots,5h-1\}, J={0,…,8⁢h−1}J=\{0,\ldots,8h-1\}, and U=8⁢h−1=2⁢m−1U=8h-1=2m-1. Let

dU\displaystyle d_{U} =lcm⁡(1,2,…,U),\displaystyle=\operatorname{lcm}(1,2,\ldots,U),
Nm\displaystyle N_{m} =13⁢h2−4⁢h=1316⁢m2−m,\displaystyle=13h^{2}-4h=\frac{13}{16}m^{2}-m,
Hm\displaystyle H_{m} =h2−3⁢h=116⁢m2−34⁢m.\displaystyle=h^{2}-3h=\frac{1}{16}m^{2}-\frac{3}{4}m.

For a prime pp, put dp=⌊logp⁡U⌋d_{p}=\lfloor\log_{p}U\rfloor and use vpv_{p} for the usual valuation, including its coefficientwise extension to polynomials. The parameter-dependent entries A⁢(a),B⁢(a),C⁢(a)A(a),B(a),C(a) and determinant Gm,a⁢(T)G_{m,a}(T) are those of (4.1); in particular the diagonal conventions in Section 4 are retained.

5.1. The source Mellin identity

For real aa with |a|>1|a|>1 put

ti0⁢(a)=∑r=1iai−rr,bi0⁢(a)=∑r=1iai−rr2,L⁢(a)=−∑r≥1a−rr,β⁢(a)=∑r≥1a−rr2.t_{i}^{0}(a)=\sum_{r=1}^{i}\frac{a^{i-r}}{r},\quad b_{i}^{0}(a)=\sum_{r=1}^{i}% \frac{a^{i-r}}{r^{2}},\quad L(a)=-\sum_{r\geq 1}\frac{a^{-r}}{r},\quad\beta(a)% =\sum_{r\geq 1}\frac{a^{-r}}{r^{2}}.

Thus L⁢(a)=log⁡(1−1/a)L(a)=\log(1-1/a) and β⁢(a)=Li2⁡(1/a)\beta(a)=\operatorname{Li}_{2}(1/a) with their real values on both components of {|a|>1}\{|a|>1\}. Define

Ai⁢j0⁢(a)=ai⁢δi⁢j,Ci⁢j0⁢(a)={(ai−aj)/(j−i),i≠j,0,i=j,A^{0}_{ij}(a)=a^{i}\delta_{ij},\qquad C^{0}_{ij}(a)=\begin{cases}(a^{i}-a^{j})% /(j-i),&i\neq j,\\ 0,&i=j,\end{cases}

and

Bi⁢j0⁢(a)={(ti0⁢(a)−tj0⁢(a))/(j−i),i≠j,bi0⁢(a),i=j.B^{0}_{ij}(a)=\begin{cases}(t_{i}^{0}(a)-t_{j}^{0}(a))/(j-i),&i\neq j,\\ b_{i}^{0}(a),&i=j.\end{cases}
Lemma 5.1 (source Mellin identity).

For |a|>1|a|>1 and all i,j≥0i,j\geq 0,

(5.1) Mi⁢j⁢(a):=Bi⁢j0⁢(a)+L⁢(a)⁢Ci⁢j0⁢(a)−β⁢(a)⁢Ai⁢j0⁢(a)=−∑r≥1a−r(i+r)⁢(j+r)=−∫01∫01xi⁢yja−x⁢y⁢𝑑x⁢𝑑y.M_{ij}(a):=B^{0}_{ij}(a)+L(a)C^{0}_{ij}(a)-\beta(a)A^{0}_{ij}(a)=-\sum_{r\geq 1% }\frac{a^{-r}}{(i+r)(j+r)}=-\int_{0}^{1}\!\!\int_{0}^{1}\frac{x^{i}y^{j}}{a-xy% }\,dx\,dy.
Proof.

The two finite identities

ti0⁢(a)+ai⁢L⁢(a)=−∑r≥1a−ri+r,bi0⁢(a)−ai⁢β⁢(a)=−∑r≥1a−r(i+r)2t_{i}^{0}(a)+a^{i}L(a)=-\sum_{r\geq 1}\frac{a^{-r}}{i+r},\qquad b_{i}^{0}(a)-a% ^{i}\beta(a)=-\sum_{r\geq 1}\frac{a^{-r}}{(i+r)^{2}}

follow by separating the first ii terms of the defining series. Taking the divided difference of the first identity and using

(i+r)−1−(j+r)−1j−i=1(i+r)⁢(j+r)\frac{(i+r)^{-1}-(j+r)^{-1}}{j-i}=\frac{1}{(i+r)(j+r)}

proves the off-diagonal case of (5.1); the second identity proves the diagonal case. Since |a|>1|a|>1, the geometric series (a−x⁢y)−1=∑r≥1a−r⁢(x⁢y)r−1(a-xy)^{-1}=\sum_{r\geq 1}a^{-r}(xy)^{r-1} converges uniformly on [0,1]2[0,1]^{2}, so termwise integration gives the last equality. ∎

Put

Dg⁢f⁢(a)=1g!⁢dgd⁢ag⁢(ag⁢f⁢(a)).D_{g}f(a)=\frac{1}{g!}\frac{d^{g}}{da^{g}}\bigl{(}a^{g}f(a)\bigr{)}.

On every compact subset of {|a|>1}\{|a|>1\} the series in (5.1), after multiplication by aga^{g}, and all its derivatives through order gg, are dominated by C⁢(1+r)g⁢ρrC(1+r)^{g}\rho^{r} with ρ<1\rho<1. Termwise differentiation is therefore valid and

(5.2) Dg⁢Mi⁢j⁢(a)=(−1)g+1⁢∑r>g(r−1g)⁢a−r(i+r)⁢(j+r).D_{g}M_{ij}(a)=(-1)^{g+1}\sum_{r>g}\frac{\binom{r-1}{g}a^{-r}}{(i+r)(j+r)}.

Indeed Dg⁢a−r=0D_{g}a^{-r}=0 for r≤gr\leq g and equals (−1)g⁢(r−1g)⁢a−r(-1)^{g}\binom{r-1}{g}a^{-r} for r>gr>g.

For completeness, the right side is exactly the finite rational table used in the determinant. If Ui⁢(a)=ai⁢(i+gg)U_{i}(a)=a^{i}\binom{i+g}{g} and Qs⁢(a)=(a/(a−1))s−1Q_{s}(a)=(a/(a-1))^{s}-1, the finite definitions of A,B,CA,B,C in Section 4 already use aa throughout. Leibniz’s rule gives Dg⁢ai=Ui⁢(a)D_{g}a^{i}=U_{i}(a) and, for s≥1s\geq 1,

as⁢L(s)⁢(a)s!=(−1)s−1s⁢Qs⁢(a),as⁢β(s)⁢(a)s!=(−1)s−1s⁢(L⁢(a)−∑r=1s−1Qr⁢(a)r).\frac{a^{s}L^{(s)}(a)}{s!}=\frac{(-1)^{s-1}}{s}Q_{s}(a),\qquad\frac{a^{s}\beta% ^{(s)}(a)}{s!}=\frac{(-1)^{s-1}}{s}\left(L(a)-\sum_{r=1}^{s-1}\frac{Q_{r}(a)}{% r}\right).

The latter follows from β′⁢(a)=L⁢(a)/a\beta^{\prime}(a)=L(a)/a. Substitution in (5.1) proves

(5.3) Dg⁢Mi⁢j⁢(a)=Bi⁢j(g)⁢(a)+L⁢(a)⁢Ci⁢j(g)⁢(a)−β⁢(a)⁢Ai⁢j(g)⁢(a).D_{g}M_{ij}(a)=B^{(g)}_{ij}(a)+L(a)C^{(g)}_{ij}(a)-\beta(a)A^{(g)}_{ij}(a).

For i=ji=j, the coefficient of L⁢(a)L(a) is −Ui⁢(a)⁢∑s=1g(i+s)−1-U_{i}(a)\sum_{s=1}^{g}(i+s)^{-1}, because

∑s=1g(−1)s−1s⁢(i+gg−s)=(i+gg)⁢∑s=1g1i+s.\sum_{s=1}^{g}\frac{(-1)^{s-1}}{s}\binom{i+g}{g-s}=\binom{i+g}{g}\sum_{s=1}^{g% }\frac{1}{i+s}.

This identity is the derivative at x=0x=0 of (i+g+xg)=∑s=0g(i+gg−s)⁢(xs)\binom{i+g+x}{g}=\sum_{s=0}^{g}\binom{i+g}{g-s}\binom{x}{s}; the coefficient of −β-\beta is Ui⁢(a)U_{i}(a). Hence the diagonal conventions, and not only the off-diagonal divided differences, are covered by (5.3).

5.2. The polynomial divisor

We first record the two polynomial divisibilities that account for the exceptional primes. All statements in this subsection are identities for every h≥1h\geq 1.

Lemma 5.2 (formal divisor at a=0a=0).

With b=a−1b=a-1,

(5.4) dU3⁢m⁢bg⁢m⁢Gm,a⁢(T)∈ℤ⁢[a,T],dU3⁢m⁢bg⁢m⁢Gm,a⁢(T)∈aNm⁢ℤ⁢[a,T].d_{U}^{3m}b^{gm}G_{m,a}(T)\in\mathbb{Z}[a,T],\qquad d_{U}^{3m}b^{gm}G_{m,a}(T)% \in a^{N_{m}}\mathbb{Z}[a,T].
Proof.

The only parameter denominators in the finite source formulas are powers of bb in

Qs⁢(a)=(aa−1)s−1.Q_{s}(a)=\left(\frac{a}{a-1}\right)^{s}-1.

After multiplying each lower row by bgb^{g}, its occurrence becomes the integer polynomial

Rs⁢(a)=bg⁢Qs⁢(a)=as⁢bg−s−bg∈ℤ⁢[a](1≤s≤g).R_{s}(a)=b^{g}Q_{s}(a)=a^{s}b^{g-s}-b^{g}\in\mathbb{Z}[a]\quad(1\leq s\leq g).

Its constant coefficient is −(−1)g-(-1)^{g}, a unit. The other source denominators are harmonic indices, summation indices, and divided-difference denominators. Every such positive index is at most UU: for example i+g≤7⁢h−1<Ui+g\leq 7h-1<U, and |j−i|≤7⁢h−1<U|j-i|\leq 7h-1<U. Multiplication of each top row by dUd_{U} and each lower row by dU2d_{U}^{2} clears them. Thus

Pm⁢(a,T):=dU3⁢m⁢bg⁢m⁢Gm,a⁢(T)∈ℤ⁢[a,T].P_{m}(a,T):=d_{U}^{3m}b^{gm}G_{m,a}(T)\in\mathbb{Z}[a,T].

To find its order at a=0a=0, work in ℚ⁢[[a]]\mathbb{Q}[[a]]. Set

ci=(i+gg),ui=ci⁢ai,hi=∑s=1g1i+s,γi=12⁢(hi2−∑s=1g1(i+s)2),c_{i}=\binom{i+g}{g},\quad u_{i}=c_{i}a^{i},\quad h_{i}=\sum_{s=1}^{g}\frac{1}% {i+s},\quad\gamma_{i}=\frac{1}{2}\left(h_{i}^{2}-\sum_{s=1}^{g}\frac{1}{(i+s)^% {2}}\right),

and L1=∑r≥1ar/rL_{1}=\sum_{r\geq 1}a^{r}/r, L2=∑r≥1ar/r2L_{2}=\sum_{r\geq 1}a^{r}/r^{2}. The source identities, coefficientwise in aa, are

(5.5) ti−L1⁢ui\displaystyle t_{i}-L_{1}u_{i} =∑k≠ick⁢aki−k−ui⁢hi,\displaystyle=\sum_{k\neq i}\frac{c_{k}a^{k}}{i-k}-u_{i}h_{i},
(5.6) bi+L1⁢ui⁢hi+L2⁢ui\displaystyle b_{i}+L_{1}u_{i}h_{i}+L_{2}u_{i} =∑k≠ick⁢ak(i−k)2+γi⁢ui.\displaystyle=\sum_{k\neq i}\frac{c_{k}a^{k}}{(i-k)^{2}}+\gamma_{i}u_{i}.

Here the bib_{i} on the left is the diagonal source entry, not the parameter b=a−1b=a-1. We use a direct coefficient check, so no auxiliary logarithmic symbol is being differentiated. For r≥0r\geq 0, expand every finite source entry in ℚ⁢[[a]]\mathbb{Q}[[a]], replace

[ar]⁢L1=1r(r≥1),[ar]⁢L2=1r2,[a^{r}]L_{1}=\frac{1}{r}\quad(r\geq 1),\qquad[a^{r}]L_{2}=\frac{1}{r^{2}},

and use

[ar]⁢ui=(i+gg)⁢[r=i],γi=∑1≤s<t≤g1(i+s)⁢(i+t).[a^{r}]u_{i}=\binom{i+g}{g}[r=i],\qquad\gamma_{i}=\sum_{1\leq s<t\leq g}\frac{% 1}{(i+s)(i+t)}.

The coefficient of the first source identity is then

[ar]⁢ti−[ar]⁢(L1⁢ui)={cr/(i−r),r≠i,−ci⁢hi,r=i,[a^{r}]t_{i}-[a^{r}](L_{1}u_{i})=\begin{cases}c_{r}/(i-r),&r\neq i,\\ -c_{i}h_{i},&r=i,\end{cases}

which is exactly the right side of (5.5). For the second identity, the coefficient is

[ar]⁢(bi+L1⁢ui⁢hi+L2⁢ui)={cr/(i−r)2,r≠i,ci⁢γi,r=i.[a^{r}]\bigl{(}b_{i}+L_{1}u_{i}h_{i}+L_{2}u_{i}\bigr{)}=\begin{cases}c_{r}/(i-% r)^{2},&r\neq i,\\ c_{i}\gamma_{i},&r=i.\end{cases}

This is the coefficient of its right side, including the diagonal correction. All sums are finite at a fixed coefficient, so these are identities in ℚ⁢[[a]]\mathbb{Q}[[a]] coefficient by coefficient. The only binomial identity used in collecting the harmonic terms is the differentiated finite identity

(i+g+xg)=∑s=0g(i+gg−s)⁢(xs)\binom{i+g+x}{g}=\sum_{s=0}^{g}\binom{i+g}{g-s}\binom{x}{s}

at x=0x=0; hence the argument does not assume a formal primitive for 1/a1/a.

For an independent indeterminate XX, form

ℋ⁢(a,X)=[C⁢(a)B⁢(a)−L1⁢(a)⁢C⁢(a)+L2⁢(a)⁢A⁢(a)−X⁢A⁢(a)].\mathcal{H}(a,X)=\begin{bmatrix}C(a)\\ B(a)-L_{1}(a)C(a)+L_{2}(a)A(a)-XA(a)\end{bmatrix}.

For a fixed k≥0k\geq 0, let eI⁢(i)=[i=k]e_{I}(i)=[i=k], vI⁢(i)=(i−k)−1v_{I}(i)=(i-k)^{-1} for i≠ki\neq k and vI⁢(k)=0v_{I}(k)=0, and wI=vI2w_{I}=v_{I}^{2}; define eJ,vJ,wJe_{J},v_{J},w_{J} in the same way. Equations (5.5)–(5.6) give the exact rank-one expansion

(5.7) [ak]⁢ℋ=ck⁢((eIvI−hk⁢eI)⁢vJ𝖳+(0−eI)⁢wJ𝖳+(vI−hk⁢eI−wI−hk⁢vI+(γk−X)⁢eI)⁢eJ𝖳).[a^{k}]\mathcal{H}=c_{k}\left(\binom{e_{I}}{v_{I}-h_{k}e_{I}}v_{J}^{\mathsf{T}% }+\binom{0}{-e_{I}}w_{J}^{\mathsf{T}}+\binom{v_{I}-h_{k}e_{I}}{-w_{I}-h_{k}v_{% I}+(\gamma_{k}-X)e_{I}}e_{J}^{\mathsf{T}}\right).

In entries, the lower block of this coefficient is

[ak]⁢(B−L1⁢C+L2⁢A−X⁢A)i⁢j=ck⁢{((i−k)⁢(j−k))−1,i≠k,j≠k,−hk⁢(j−k)−1−(j−k)−2,i=k,j≠k,−(i−k)−2−hk⁢(i−k)−1,i≠k,j=k,γk−X,i=j=k.[a^{k}]\bigl{(}B-L_{1}C+L_{2}A-XA\bigr{)}_{ij}=c_{k}\begin{cases}((i-k)(j-k))^% {-1},&i\neq k,\ j\neq k,\\ -h_{k}(j-k)^{-1}-(j-k)^{-2},&i=k,\ j\neq k,\\ -(i-k)^{-2}-h_{k}(i-k)^{-1},&i\neq k,\ j=k,\\ \gamma_{k}-X,&i=j=k.\end{cases}

The first feature has weight kk; the second is present only when k∈Ik\in I, and the third only when k∈Jk\in J. A nonzero 2⁢m2m-row determinant term must choose 2⁢m2m distinct rank-one features. Since I=[h,5⁢h)I=[h,5h) and J=[0,8⁢h)J=[0,8h), the least possible total feature weight is obtained from two copies of 0,…,h−10,\ldots,h-1 and three copies of h,…,3⁢h−1h,\ldots,3h-1. Its value is

2⁢∑k=0h−1k+3⁢∑k=h3⁢h−1k=13⁢h2−4⁢h=Nm.2\sum_{k=0}^{h-1}k+3\sum_{k=h}^{3h-1}k=13h^{2}-4h=N_{m}.

Finite multilinearity is legitimate coefficientwise: a coefficient of ara^{r} can involve only features of weight at most rr. Thus aNm∣detℋ⁢(a,X)a^{N_{m}}\mid\det\mathcal{H}(a,X) in ℚ⁢[[a]]⁢[X]\mathbb{Q}[[a]][X]. The determinant-one row shear gives detℋ⁢(a,X)=Gm,a⁢(X−L2⁢(a))\det\mathcal{H}(a,X)=G_{m,a}(X-L_{2}(a)); since L2∈a⁢ℚ⁢[[a]]L_{2}\in a\mathbb{Q}[[a]], translation preserves the order at zero. Therefore aNma^{N_{m}} divides PmP_{m} in ℚ⁢[a,T]\mathbb{Q}[a,T]. As Pm∈ℤ⁢[a,T]P_{m}\in\mathbb{Z}[a,T] and the divisor is the monomial aNma^{N_{m}}, the quotient is also in ℤ⁢[a,T]\mathbb{Z}[a,T]. ∎

Lemma 5.3 (endpoint pole divisor).

Coefficientwise in TT,

orda=1⁡G4⁢h,a⁢(T)≥3⁢h−h2.\operatorname{ord}_{a=1}G_{4h,a}(T)\geq 3h-h^{2}.

Consequently

(5.8) dU3⁢m⁢(a−1)Hm⁢Gm,a⁢(T)∈aNm⁢ℤ⁢[a,T].d_{U}^{3m}(a-1)^{H_{m}}G_{m,a}(T)\in a^{N_{m}}\mathbb{Z}[a,T].

The exponent 3⁢h−h23h-h^{2} is a sufficient lower bound; equality for every hh is not asserted.

Proof.

Put b=a−1b=a-1 and f⁢(x)=(x+gg)f(x)=\binom{x+g}{g}. At a=1a=1, the full top block, including its diagonal, is the divided-difference polynomial

C⁢(x,y)=f⁢(x)−f⁢(y)y−x,C⁢(x,x)=−f′⁢(x),C(x,y)=\frac{f(x)-f(y)}{y-x},\qquad C(x,x)=-f^{\prime}(x),

of total degree at most g−1g-1. For the lower block, the source Mellin identity gives

Polynomial division in rr yields

(r−1g)(r+i)⁢(r+j)=∑d=0g−2qd⁢(i,j)⁢rd+O⁢(r−1),degi,j⁡qd≤g−2−d.\frac{\binom{r-1}{g}}{(r+i)(r+j)}=\sum_{d=0}^{g-2}q_{d}(i,j)r^{d}+O(r^{-1}),% \qquad\deg_{i,j}q_{d}\leq g-2-d.

The power sum ∑r≥1rd⁢(1+b)−r\sum_{r\geq 1}r^{d}(1+b)^{-r} has pole order at most d+1d+1; the remainder is O⁢(1+|log⁡b|)O(1+|\log b|). Since BB is rational in bb, while L⁢C−Li2⁡(1/a)⁢A=O⁢(1+|log⁡b|)LC-\operatorname{Li}_{2}(1/a)A=O(1+|\log b|), this identifies its entire principal part, including diagonal entries:

[b−s]⁢Bi⁢j⁢(1+b)=Ps⁢(i,j),deg⁡Ps≤g−1−s(1≤s≤g−1).[b^{-s}]B_{ij}(1+b)=P_{s}(i,j),\qquad\deg P_{s}\leq g-1-s\quad(1\leq s\leq g-1).

Apply forward differences of orders u=0,…,m−1u=0,\ldots,m-1 to the rows in each block and v=0,…,2⁢m−1v=0,\ldots,2m-1 to columns. These are unitriangular transforms, so they preserve the determinant. The degree bounds imply

ordbC^u⁢v≥[u+v≥g],ordb(B^−TA^)u⁢v≥min(0,u+v−g+1).\operatorname{ord}_{b}\widehat{C}_{uv}\geq[u+v\geq g],\qquad\operatorname{ord}% _{b}(\widehat{B}-T\widehat{A})_{uv}\geq\min(0,u+v-g+1).

In a determinant term, let kk be the number of lower entries with a negative bound. Then 0≤k≤g−10\leq k\leq g-1, and their distinct row and column indices give a total order at least k⁢(k−g)k(k-g). Their columns lie among 0,…,g−20,\ldots,g-2; hence at most g−kg-k top entries can have order-zero bounds, so at least m−g+km-g+k top entries contribute order at least one. Every determinant term has order at least

m−g+k+k⁢(k−g)=m−g+k⁢(k−g+1).m-g+k+k(k-g)=m-g+k(k-g+1).

For m=4⁢hm=4h, g=2⁢hg=2h, this is

2⁢h+(k−h)⁢(k−h+1)−h⁢(h−1)≥3⁢h−h2,2h+(k-h)(k-h+1)-h(h-1)\geq 3h-h^{2},

because (k−h)⁢(k−h+1)≥0(k-h)(k-h+1)\geq 0 for integral kk. This proves the order bound, including all diagonal entries.

By Lemma 5.2, Pm=dU3⁢m⁢b8⁢h2⁢G=aNm⁢SP_{m}=d_{U}^{3m}b^{8h^{2}}G=a^{N_{m}}S with S∈ℤ⁢[a,T]S\in\mathbb{Z}[a,T]. The pole bound shows that b7⁢h2+3⁢hb^{7h^{2}+3h} divides PmP_{m} in ℚ⁢[a,T]\mathbb{Q}[a,T]. This divisor is monic, so division preserves integrality; it is coprime to aNma^{N_{m}}. Cancelling it yields

dU3⁢m⁢b8⁢h2−(7⁢h2+3⁢h)⁢G=dU3⁢m⁢bHm⁢G∈aNm⁢ℤ⁢[a,T],d_{U}^{3m}b^{8h^{2}-(7h^{2}+3h)}G=d_{U}^{3m}b^{H_{m}}G\in a^{N_{m}}\mathbb{Z}[% a,T],

as claimed. The argument also covers h=1,2h=1,2, when Hm=−2H_{m}=-2; in those cases the displayed expression is an identity of rational functions whose right side is the stated integer polynomial. ∎

5.3. Primewise valuation bounds

For a fixed integer aa with |a|≥2|a|\geq 2, define

Fm,p⁢(a)=3⁢m⁢dp+Hm⁢vp⁢(a−1)−Nm⁢vp⁢(a).F_{m,p}(a)=3md_{p}+H_{m}v_{p}(a-1)-N_{m}v_{p}(a).

We next define a second, moving-prime bound. For an odd prime satisfying p2>U+gp^{2}>U+g, put

r=gmodp,κn=[nmodp≥p−r],θn=(κn−1)⁢[n≥p⁢ or ⁢p≤g],r=g\bmod p,\qquad\kappa_{n}=[n\bmod p\geq p-r],\qquad\theta_{n}=(\kappa_{n}-1)% [n\geq p\text{ or }p\leq g],

where κn=0\kappa_{n}=0 if r=0r=0. Define the integer Wm⁢(p)W_{m}(p) by the following deterministic rule (it is the chosen upper bound, not an undefined optimum):

  • •

    if p2≤U+gp^{2}\leq U+g, set Wm⁢(p)=3⁢m⁢dpW_{m}(p)=3md_{p};

  • •

    if p2>U+gp^{2}>U+g and pp lies on a positive-ratio wall, set Wm⁢(p)=3⁢mW_{m}(p)=3m;

  • •

    otherwise, for p/m<1/2p/m<1/2, set Wm⁢(p)W_{m}(p) to the smaller of the two integer right sides in (5.9); for 1/2<p/m<5/21/2<p/m<5/2, generate the groups from the affine endpoints below, sum the displayed row and column potentials in Table 5.1 over those groups, and take that exact integer objective;

  • •

    if p>U+gp>U+g, set Wm⁢(p)=0W_{m}(p)=0.

At the low-ratio endpoint p/m=1/2p/m=1/2, the wall convention 3⁢m3m applies. The group widths are integers because 4∣m4\mid m and all endpoint intercepts have denominator at most four; consequently the high-ratio objective is an integer, not a real relaxation. These clauses define Wm⁢(p)W_{m}(p) for every prime before it is used in 5.4. The finite collection of walls in [1/128,5/2][1/128,5/2] is defined below. These rules are compatible at overlapping cases: the generic denominator bound is used first, and p>U+gp>U+g is outside every positive-ratio cell.

Lemma 5.4 (coefficientwise entry bounds).

For every integer specialization aa and every coefficient in TT, the valuation of the determinant satisfies

−vp⁢(Gm,a)≤Wm⁢(p)+g⁢m⁢vp⁢(a−1).-v_{p}(G_{m,a})\leq W_{m}(p)+gm\,v_{p}(a-1).

Also, for every prime pp,

−vp⁢(Gm,a)≤Fm,p⁢(a).-v_{p}(G_{m,a})\leq F_{m,p}(a).
Proof.

The second inequality follows directly from (5.8). For the first, multiply every lower row by bgb^{g}, so that det[C;bg⁢(B−T⁢A)]=bg⁢m⁢Gm,a⁢(T)\det[C;b^{g}(B-TA)]=b^{gm}G_{m,a}(T). When p2≤U+gp^{2}\leq U+g, the factors dUd_{U} and dU2d_{U}^{2} clear top and lower rows, giving the claimed 3⁢m⁢dp3md_{p} bound. When p>U+gp>U+g, every source denominator is a pp-unit and the scaled entries are pp-integral.

It remains to consider odd pp with p2>U+gp^{2}>U+g. Every relevant upper index is less than p2p^{2}. Kummer’s carry rule therefore gives

vp⁢(n+gg)=κn.v_{p}\binom{n+g}{g}=\kappa_{n}.

If p∣sp\mid s, then g−sg-s has the same units digit as gg, so

vp⁢(n+gg−s)≥κn;v_{p}\binom{n+g}{g-s}\geq\kappa_{n};

and, if p∣sp\mid s and s≤ns\leq n, vp⁢(n−s+gg)≥κnv_{p}\binom{n-s+g}{g}\geq\kappa_{n}. No second carry is possible because all sums are below p2p^{2}. After multiplying by bgb^{g}, each QsQ_{s} is the primitive polynomial RsR_{s} above, whose Gauss valuation is zero. In these sums, terms with p∤sp\nmid s are pp-integral; in the mixed Bi⁢iB_{ii} terms, a single pp-denominator contributes at worst −1≥κi−2-1\geq\kappa_{i}-2, since κi≤1\kappa_{i}\leq 1. Every nonzero source denominator and every row or column difference is less than p2p^{2}, hence has pp-valuation at most one. The ultrametric inequality now gives the following lower bounds for scaled entries:

Entry Lower bound for vpv_{p}
Ci⁢jC_{ij}, i≠ji\neq j min⁡(κi,κj)−[i≡j(modp)]\min(\kappa_{i},\kappa_{j})-[i\equiv j\pmod{p}]
Ci⁢iC_{ii} (κi−1)⁢[p≤g](\kappa_{i}-1)[p\leq g]
(bg⁢B)i⁢j(b^{g}B)_{ij}, i≠ji\neq j min⁡(θi,θj)−[i≡j(modp)]\min(\theta_{i},\theta_{j})-[i\equiv j\pmod{p}]
(bg⁢B)i⁢i(b^{g}B)_{ii}, i≥pi\geq p or 2⁢p≤g2p\leq g κi−2\kappa_{i}-2
(bg⁢B)i⁢i(b^{g}B)_{ii}, i<pi<p and p≤g<2⁢pp\leq g<2p −1-1
(bg⁢B)i⁢i(b^{g}B)_{ii}, i<pi<p and p>gp>g 0

For Ci⁢iC_{ii}, the case p≤gp\leq g uses the general bound vp⁢(Ui/(i+s))≥κi−1v_{p}(U_{i}/(i+s))\geq\kappa_{i}-1, since i+s<p2i+s<p^{2}. If p>gp>g and p∣i+sp\mid i+s, then 1≤s≤g<p1\leq s\leq g<p, so imodp=p−si\bmod p=p-s; adding gg to ii produces exactly one base-pp carry and hence κi=1\kappa_{i}=1. Thus every term with a pp-divisible denominator is still pp-integral, and all other terms are pp-integral because vp⁢(Ui)=κi≥0v_{p}(U_{i})=\kappa_{i}\geq 0. For the lower diagonal, a squared denominator in the first sum requires i≥pi\geq p; two pp-denominators in the correction sum require 2⁢p≤g2p\leq g. In either case the relevant binomial coefficient has valuation at least κi\kappa_{i}. If p≤g<2⁢pp\leq g<2p and i<pi<p, at most one denominator is divisible by pp; if p>gp>g and i<pi<p, none is. The term −T⁢A-TA is integral after the row scaling and does not weaken these bounds.

By the Leibniz expansion, minus the determinant valuation is at most the maximum assignment weight formed by negating these entry lower bounds. The exact profile Wm⁢(p)W_{m}(p) bounds that assignment in each range. The certificate details follow. ∎

5.4. Exact moving-prime profile

Let ρ=p/m\rho=p/m. For a residue v∈{0,…,p−1}v\in\{0,\ldots,p-1\}, the copy counts are

cI⁢(v)=#⁢{n∈ℤ:1/4≤v/m+n⁢ρ<5/4},cJ⁢(v)=#⁢{n∈ℤ:0≤v/m+n⁢ρ<2}.c_{I}(v)=\#\{n\in\mathbb{Z}:1/4\leq v/m+n\rho<5/4\},\qquad c_{J}(v)=\#\{n\in% \mathbb{Z}:0\leq v/m+n\rho<2\}.

The carry flag is constant on each residue group. For p<gp<g, let KI,KJK_{I},K_{J} count the killed row and column copies (κv=1\kappa_{v}=1), and put

SU=∑κv=0min⁡(2⁢cI⁢(v),cJ⁢(v)),SK=∑κv=1min⁡(2⁢cI⁢(v),cJ⁢(v)).S_{U}=\sum_{\kappa_{v}=0}\min(2c_{I}(v),c_{J}(v)),\qquad S_{K}=\sum_{\kappa_{v% }=1}\min(2c_{I}(v),c_{J}(v)).

The two feasible assignment bounds are

(5.9) Wm⁢(p)≤min⁡{m+SU, 3⁢m−2⁢KI−KJ+SK}.W_{m}(p)\leq\min\{m+S_{U},\;3m-2K_{I}-K_{J}+S_{K}\}.

Indeed, after subtracting the lower-row baseline mm, the assignment score is x−zx-z, where xx counts unkilled same-residue matches and zz killed off-residue matches. If yy is the number of killed same-residue matches, then x≤SUx\leq S_{U}, y≤SKy\leq S_{K}, and counting killed row and column copies gives z+y≥2⁢KI+KJ−2⁢m+xz+y\geq 2K_{I}+K_{J}-2m+x. These yield the two inequalities.

All group endpoints are generated by a finite exact rule. For a fixed open wall cell and any interior rational sample ρ0\rho_{0}, set q=⌊1/(2⁢ρ0)⌋q=\lfloor 1/(2\rho_{0})\rfloor and order the affine endpoints

(0,0),(0,1),(−1/2,q+1),(x,−⌊x/ρ0⌋)⁢(x=1/4,5/4,2),(0,0),\ (0,1),\ (-1/2,q+1),\quad(x,-\lfloor x/\rho_{0}\rfloor)\ (x=1/4,5/4,2),

by their values A+B⁢ρ0A+B\rho_{0}. Consecutive endpoints give a group of width A+B⁢ρA+B\rho. At its midpoint tt, the II- and JJ-copy lists are respectively

⌈1/4−tρ0⌉≤n<⌈5/4−tρ0⌉,⌈−tρ0⌉≤n<⌈2−tρ0⌉,\left\lceil\frac{1/4-t}{\rho_{0}}\right\rceil\leq n<\left\lceil\frac{5/4-t}{% \rho_{0}}\right\rceil,\qquad\left\lceil\frac{-t}{\rho_{0}}\right\rceil\leq n<% \left\lceil\frac{2-t}{\rho_{0}}\right\rceil,

and the group is killed precisely when t≥(q+1)⁢ρ0−1/2t\geq(q+1)\rho_{0}-1/2. These data remain constant throughout the open cell. The full wall set in a compact ratio interval is generated by

𝒲⁢([r0,r1])={r0,r1}∪{x−yn:x,y∈{0,1/4,5/4,2,−1/2},x>y,n∈ℕ,r0<x−yn<r1}.\mathcal{W}([r_{0},r_{1}])=\{r_{0},r_{1}\}\cup\left\{\frac{x-y}{n}:\begin{% aligned} &x,y\in\{0,1/4,5/4,2,-1/2\},\quad x>y,\\ &n\in\mathbb{N},\quad r_{0}<\frac{x-y}{n}<r_{1}\end{aligned}\right\}.

It is finite because x−y≤5/2x-y\leq 5/2 and n<(x−y)/r0n<(x-y)/r_{0}.

For ρ∈[δ,1/2]\rho\in[\delta,1/2], δ=1/128\delta=1/128, the rule gives 756 lower-envelope affine pieces. Their exact integral is

(5.10) L∗=14482763147401949648552601008004621272602980310427967495297256273700103967348956336582853333504509057044430295710028387102371404098881580803157259376918521625735839461675553873436297217652662216162782957043593966060046854826150978176673015236224000.L_{*}=\frac{\begin{array}[]{c}\texttt{1448276314740194964855260100800462127260% 298}\\ \texttt{03104279674952972562737001039673489563365828533335}\\ \texttt{0450905704443029571002838710237}\end{array}}{\begin{array}[]{c}\texttt% {140409888158080315725937691852162573583946167555}\\ \texttt{38734362972176526622161627829570435939660600468548}\\ \texttt{26150978176673015236224000}\end{array}}.

In each array, concatenate its three rows to obtain the integer. This value is obtained by integrating the minimum in (5.9) on each rational group cell, splitting at its rational affine crossings. The formula above is the exact reconstruction rule; no optimizer is used.

For 0<ρ<δ0<\rho<\delta, zero column potentials give Wm⁢(p)≤3⁢m−2⁢KIW_{m}(p)\leq 3m-2K_{I}. Since an interval of mm consecutive integers contains at least ⌊m/p⌋⁢(gmodp)\lfloor m/p\rfloor(g\bmod p) killed indices, the profile ftail⁢(ρ)=3−2⁢{1/(2⁢ρ)}+2⁢ρf_{\rm tail}(\rho)=3-2\{1/(2\rho)\}+2\rho satisfies Wm⁢(p)/m≤ftail⁢(ρ)W_{m}(p)/m\leq f_{\rm tail}(\rho). Writing δ=1/(2⁢Q)\delta=1/(2Q) with Q=64Q=64 and substituting x=1/(2⁢ρ)x=1/(2\rho) gives

∫0δ(3−2⁢{12⁢ρ})⁢𝑑ρ=12⁢Q+∑q≥Q(1q−log⁡(1+1/q)).\int_{0}^{\delta}\left(3-2\left\{\frac{1}{2\rho}\right\}\right)d\rho=\frac{1}{% 2Q}+\sum_{q\geq Q}\left(\frac{1}{q}-\log(1+1/q)\right).

For each q≥Qq\geq Q, the summand differs from 1/(2⁢q⁢(q+1))1/(2q(q+1)) by

∫01s⁢(1−s)q⁢(q+s)⁢(q+1)⁢𝑑s≤16⁢q2⁢(q+1).\int_{0}^{1}\frac{s(1-s)}{q(q+s)(q+1)}\,ds\leq\frac{1}{6q^{2}(q+1)}.

Summing this bound and integrating the added 2⁢ρ2\rho term yields

(5.11) ∫0δftail⁢(ρ)⁢𝑑ρ≤2⁢δ+2⁢δ2=1298192.\int_{0}^{\delta}f_{\rm tail}(\rho)\,d\rho\leq 2\delta+2\delta^{2}=\frac{129}{% 8192}.

For 1/2<ρ<5/21/2<\rho<5/2, p>gp>g, so each group has a carry bit k∈{0,1}k\in\{0,1\}. If nn denotes a copy index, put θ=(k−1)⁢[n≥1]\theta=(k-1)[n\geq 1]. A row type is (j,n,e,k)(j,n,e,k), where jj is its group, nn is an II-copy and e∈{0,1}e\in\{0,1\} is the top or lower block; a column type is (j,n,k)(j,n,k) with nn a JJ-copy. Order row types by increasing group, then copy, then e=0,1e=0,1; order column types by increasing group then copy. For a row type rr and column type cc, the required potential inequality is

ur+vc≥wr⁢c.u_{r}+v_{c}\geq w_{rc}.

For different groups the right side is −min⁡(kr,kc)-\min(k_{r},k_{c}) in the top block and −min⁡(θr,θc)-\min(\theta_{r},\theta_{c}) in the lower block. For the same group but distinct copies add 11. For a same-index top diagonal use 0; for a same-index lower diagonal use (2−kr)(2-k_{r}) if n≥1n\geq 1, and 0 if n=0n=0. These are exactly the negated entry bounds of Lemma 5.4, including both diagonal cases. The following integer vectors give feasible potentials on every large-ratio interval; spaces separate successive coordinates and the semicolon separates the row and column vectors. The group and copy ordering is the rule just given. Each group contains exactly m⁢(Aj+Bj⁢ρ)m(A_{j}+B_{j}\rho) residues; this is an integer because mm is divisible by four and all endpoint intercepts have denominator at most four. Thus the potential objective is an integer upper bound at every prime ratio, not merely a real-valued relaxation.

The eleven large-ratio intervals are exactly the walls generated by 𝒲⁢([1/2,5/2])\mathcal{W}([1/2,5/2]). For each interval, the group formula above determines the row and column types, and the displayed vectors satisfy all the pairwise rational inequalities. The edge, diagonal, and wall comparisons are generated by the same displayed rule. Summing the type potentials times their affine group widths gives the objective column; taking its exact integral over the high cells yields

∫1/25/2fhigh⁢(ρ)⁢𝑑ρ=287192.\int_{1/2}^{5/2}f_{\rm high}(\rho)\,d\rho=\frac{287}{192}.

At a wall use Wm⁢(p)=3⁢mW_{m}(p)=3m; there are finitely many walls, so this changes the prime sum by O⁢(m⁢log⁡m)O(m\log m) for each mm.

Negative exponents are allowed; Δm,a>0\Delta_{m,a}>0 is a rational number. The product is finite: if p>U+gp>U+g and p∤a⁢(a−1)p\nmid a(a-1), both entries in the minimum are zero. Lemma 5.4 implies coefficientwise that

(5.16) Δm,a⁢Gm,a⁢(T)∈ℤ⁢[T].\Delta_{m,a}G_{m,a}(T)\in\mathbb{Z}[T].

This is a specialization-wise p-adic argument; it does not claim that the sharp scalar Δm,a\Delta_{m,a} is the specialization of an integer polynomial in aa.

Since gcd⁡(a,a−1)=1\gcd(a,a-1)=1, the exceptional sets p∣ap\mid a and p∣a−1p\mid a-1 are disjoint. For a fixed p∣ap\mid a,

Fm,p=O⁢(m⁢log⁡m)−Nm⁢vp⁢(a),Wm⁢(p)+g⁢m⁢vp⁢(a−1)=Wm⁢(p),F_{m,p}=O(m\log m)-N_{m}v_{p}(a),\qquad W_{m}(p)+gmv_{p}(a-1)=W_{m}(p),

and the quadratic negative term makes Fm,pF_{m,p} the minimum for all sufficiently large mm. For a fixed p∣a−1p\mid a-1,

Fm,p=O⁢(m⁢log⁡m)+Hm⁢vp⁢(a−1),Wm⁢(p)+g⁢m⁢vp⁢(a−1),F_{m,p}=O(m\log m)+H_{m}v_{p}(a-1),\qquad W_{m}(p)+gmv_{p}(a-1),

and g⁢m−Hm=7⁢h2+3⁢hgm-H_{m}=7h^{2}+3h makes Fm,pF_{m,p} eventually the minimum. These comparisons apply also to p=2p=2, which divides exactly one of a,a−1a,a-1. For every other fixed prime the moving profile applies, with the p2≤U+gp^{2}\leq U+g range contributing o⁢(m2)o(m^{2}) in aggregate: Put X=U+gX=U+g. The squarefull part is bounded without counting a prime more than once by

∑p≤X3⁢m⁢dp⁢log⁡p≤3⁢m⁢∑j=1⌊log2⁡U⌋ϑ⁢(min⁡{X,U1/j})=O⁢(m3/2⁢log⁡m)=o⁢(m2),\sum_{p\leq\sqrt{X}}3md_{p}\log p\leq 3m\sum_{j=1}^{\lfloor\log_{2}U\rfloor}% \vartheta\!\left(\min\{\sqrt{X},U^{1/j}\}\right)=O(m^{3/2}\log m)=o(m^{2}),

where ϑ⁢(x)=∑p≤xlog⁡p\vartheta(x)=\sum_{p\leq x}\log p. The displayed equality is an upper-bound comparison (the left side is bounded by the right side), since dpd_{p} is the number of admissible exponent layers and each layer is charged to pj≤Up^{j}\leq U; the extra log⁡m\log m is harmless after normalization.

On any fixed positive ratio interval, Wm⁢(p)≤m⁢f⁢(p/m)W_{m}(p)\leq mf(p/m) with ff bounded and piecewise affine, apart from the finite wall values. The weighted prime number theorem, obtained from the ordinary PNT by partial summation, gives

1m⁢∑pf⁢(p/m)⁢log⁡p⟶∫f⁢(ρ)⁢𝑑ρ.\frac{1}{m}\sum_{p}f(p/m)\log p\longrightarrow\int f(\rho)\,d\rho.

For 0<ρ<ε0<\rho<\varepsilon, first remove the already negligible range p≤U+gp\leq\sqrt{U+g} and then omit U+g<p≤ε⁢m\sqrt{U+g}<p\leq\varepsilon m; there dp=1d_{p}=1 and the crude bound 3⁢m⁢ϑ⁢(ε⁢m)3m\vartheta(\varepsilon m) has normalized limsup at most 3⁢ε3\varepsilon. Apply the weighted PNT on [ε,δ][\varepsilon,\delta] and then let ε↓0\varepsilon\downarrow 0. The exact tail bound (5.11), the low integral (5.10), and the high integral therefore imply

lim supm→∞4∣m1m2⁢∑p∤a⁢(a−1)Em,p⁢(a)⁢log⁡p≤K.\limsup_{\begin{subarray}{c}m\to\infty\\ 4\mid m\end{subarray}}\frac{1}{m^{2}}\sum_{p\nmid a(a-1)}E_{m,p}(a)\log p\leq K.

The fixed exceptional primes contribute

Hmm2⁢log⁡|a−1|−Nmm2⁢log⁡|a|⟶116⁢log⁡|a−1|−1316⁢log⁡|a|.\frac{H_{m}}{m^{2}}\log|a-1|-\frac{N_{m}}{m^{2}}\log|a|\longrightarrow\frac{1}% {16}\log|a-1|-\frac{13}{16}\log|a|.

We have proved the following fixed-base estimate.

Proposition 5.5 (P0 fixed-base denominator rate).

For every fixed integer |a|≥2|a|\geq 2, the rational number Δm,a\Delta_{m,a} in (5.15) satisfies (5.16) and

lim supm→∞4∣mlog⁡Δm,am2≤K+116⁢log⁡|a−1|−1316⁢log⁡|a|,K<2.542002.\limsup_{\begin{subarray}{c}m\to\infty\\ 4\mid m\end{subarray}}\frac{\log\Delta_{m,a}}{m^{2}}\leq K+\frac{1}{16}\log|a-% 1|-\frac{13}{16}\log|a|,\qquad K<2.542002.

The statement is for each fixed base. In particular, its finite-mm remainder is not uniform as |a|→∞|a|\to\infty.

Completion of the estimate.

The formal divisor and pole lemmas, Kummer bounds, residue-cell formulas, exceptional-prime comparisons, and PNT passage are all-mm derivations. The low profile is reconstructed by the rational wall-and-crossing rule above. The high profile is hand-checkable from the printed potential vectors and the stated type-generation rule: each vector pair reduces the full assignment inequality to finitely many integer comparisons. The low profile has 756 affine pieces and the high profile eleven cells. The all-mm conclusion uses the displayed identities, the finite comparison count above, and the weighted prime number theorem.

6. Positive logarithmic energy on an interval

This section records the analytic passage for the positive P0 determinant, including the dependence on the base. The finite determinant statement is for integers qq with 2≤q≤112\leq q\leq 11; a real parameter is used only in the continuum interpolation. All measures, intervals, and the contour below are fixed as qq varies. The two endpoint reference measures are the exact data in Tables A.1 and A.2.

Put m∈4⁢ℕm\in 4\mathbb{N}, m≥8m\geq 8, g=m/2g=m/2,

Im={m/4,…,5⁢m/4−1},Jm={0,…,2⁢m−1},E=[1/4,5/4],I_{m}=\{m/4,\ldots,5m/4-1\},\qquad J_{m}=\{0,\ldots,2m-1\},\qquad E=[1/4,5/4],

and fix

Γ={ξ+A⁢cos⁡u+i⁢B⁢sin⁡u:0≤u<2⁢π},(ξ,A,B)=(1128110000,1278310000,229200).\Gamma=\{\xi+A\cos u+iB\sin u:0\leq u<2\pi\},\quad(\xi,A,B)=\left(\frac{11281}% {10000},\frac{12783}{10000},\frac{229}{200}\right).

Write Δ⁢(X)=∏a<b(xb−xa)\Delta(X)=\prod_{a<b}(x_{b}-x_{a}) and K⁢(x,y)=(x+y)−1K(x,y)=(x+y)^{-1}. The source function and the frequency weight at base q>1q>1 are

Fg,q⁢(z)=qz⁢(z+gg),Ui⁢(q)=qi⁢(i+gg),wr,q=(r−1g)⁢q−r(r>g).F_{g,q}(z)=q^{z}\binom{z+g}{g},\qquad U_{i}(q)=q^{i}\binom{i+g}{g},\qquad w_{r% ,q}=\binom{r-1}{g}q^{-r}\quad(r>g).

For integer qq, let Gm,qG_{m,q} be the P0 determinant of Section 4, with a=qa=q. The diagonal contour identity is

(6.1) Ci⁢j(g)⁢(q)=−∮m⁢ΓFg,q⁢(z)(z−i)⁢(z−j)⁢d⁢z2⁢π⁢i+(log⁡q)⁢Ui⁢(q)⁢ 1i=j.C^{(g)}_{ij}(q)=-\oint_{m\Gamma}\frac{F_{g,q}(z)}{(z-i)(z-j)}\frac{dz}{2\pi i}% +(\log q)U_{i}(q)\,\mathbf{1}_{i=j}.

For i≠ji\neq j this is the divided-difference residue identity; for i=ji=j it follows by differentiating Fg,qF_{g,q}, since

Fg,q′⁢(i)=Ui⁢(q)⁢(log⁡q+∑s=1g1i+s).F_{g,q}^{\prime}(i)=U_{i}(q)\left(\log q+\sum_{s=1}^{g}\frac{1}{i+s}\right).

Expanding the rational moment expression in the frequency basis and applying Cauchy–Binet [4] gives an absolutely convergent sum over R⊂{g+1,g+2,…}R\subset\{g+1,g+2,\ldots\}, |R|=m|R|=m, with weight ∏r∈Rwr,q\prod_{r\in R}w_{r,q}. After choosing kk diagonal rows S⊂ImS\subset I_{m} and putting d=m−kd=m-k, its absolute integrand is

(6.2) Qm,q⁢(S,R,Z)=\displaystyle Q_{m,q}(S,R,Z)={} (∏i∈S(log⁡q)⁢Ui⁢(q))⁢(∏r∈Rwr,q)⁢(∏z∈Z|Fg,q⁢(z)|)\displaystyle\left(\prod_{i\in S}(\log q)U_{i}(q)\right)\left(\prod_{r\in R}w_% {r,q}\right)\left(\prod_{z\in Z}|F_{g,q}(z)|\right)
×|detKIm∖S,−Z⁢detKIm,R⁢detK(−Z,R),Jm∖S|.\displaystyle\times\left|\det K_{I_{m}\setminus S,-Z}\det K_{I_{m},R}\det K_{(% -Z,R),J_{m}\setminus S}\right|.

where Z=(z1,…,zd)∈(m⁢Γ)dZ=(z_{1},\ldots,z_{d})\in(m\Gamma)^{d}. The integration measure is ∏|d⁢z|/(2⁢π)\prod|dz|/(2\pi) and the symmetrization factor is 1/d!1/d!. The three Cauchy factors have, after restoring the deleted fixed-grid factors, the same three Vandermonde interactions as at q=2q=2: contour-contour, pinned- pinned, and frequency-frequency each have coefficient one; pinned-contour has coefficient two; pinned-frequency and contour-frequency each have coefficient one. In particular, no factor depending on qq enters the quadratic interaction energy.

Cauchy–Binet energy expansion [4].

The rational moment expression is obtained by expanding the two Cauchy kernels geometrically and using the exact generating identity

∑r≥g+1(r−1g)⁢(t/q)r=(tq−t)g+1,0≤t<q.\sum_{r\geq g+1}\binom{r-1}{g}(t/q)^{r}=\left(\frac{t}{q-t}\right)^{g+1},% \qquad 0\leq t<q.

Inserting these moments and applying

det(X⁢Y)=∑|R|=mdetX:,R⁢detYR,:\det(XY)=\sum_{|R|=m}\det X_{:,R}\det Y_{R,:}

gives the sum over the full frequency sets RR stated above. Splitting the diagonal term in (6.1) row by row chooses S⊂ImS\subset I_{m}; the remaining d=m−|S|d=m-|S| rows are represented by contour variables ZZ, with the factor 1/d!1/d! from their antisymmetrization. For any two equal-size sets, the Cauchy determinant identity [6]

det(1xi+yj)i,j=1r=Δ⁢(x)⁢Δ⁢(y)∏i,j(xi+yj)\det\left(\frac{1}{x_{i}+y_{j}}\right)_{i,j=1}^{r}=\frac{\Delta(x)\Delta(y)}{% \prod_{i,j}(x_{i}+y_{j})}

converts each of the three kernel minors into a Vandermonde quotient. Restoring the fixed-grid Vandermonde factors leaves contour-contour, pinned-pinned, and frequency-frequency interactions with coefficient one, pinned-contour with coefficient two, and the other two mixed interactions with coefficient one. Taking absolute values gives exactly (6.2); all signs and qq-powers are one-body terms. For fixed mm, the Cauchy minors have at most polynomial growth in the frequencies and wr,q=Oq⁢(rg⁢q−r)w_{r,q}=O_{q}(r^{g}q^{-r}). The absolute frequency sum therefore converges, and increasing finite truncations converge to its full absolute envelope. ∎

For the normalization, the signed Cauchy–Binet expansion [4] can be written explicitly. Put n=m/4n=m/4, Y=S⊎ZY=S\uplus Z, and

Dm⁢(a)\displaystyle D_{m}(a) =(a−n)!⁢(n+m−1−a)!⁢a!⁢(2⁢m−1−a)!,\displaystyle=(a-n)!(n+m-1-a)!a!(2m-1-a)!,
Pm⁢(z)\displaystyle P_{m}(z) =∏a∈Im⊎Jm(z−a),Qm∗⁢(r)=∏a∈Im⊎Jm(r+a).\displaystyle=\prod_{a\in I_{m}\uplus J_{m}}(z-a),\qquad Q_{m}^{*}(r)=\prod_{a% \in I_{m}\uplus J_{m}}(r+a).

Then

Gm,q=\displaystyle G_{m,q}={} Δ⁢(Im)2⁢Δ⁢(Jm)⁢∑S⊂Im(−1)|S|⁢(n+1)⁢(log⁡q)|S|d!⁢∑|R|=m(∏a∈SUa⁢(q)Dm⁢(a))⁢(∏r∈Rwr,q)\displaystyle\Delta(I_{m})^{2}\Delta(J_{m})\sum_{S\subset I_{m}}\frac{(-1)^{|S% |(n+1)}(\log q)^{|S|}}{d!}\sum_{|R|=m}\left(\prod_{a\in S}\frac{U_{a}(q)}{D_{m% }(a)}\right)\left(\prod_{r\in R}w_{r,q}\right)
×∮(m⁢Γ)dΔ⁢(Y)2⁢Δ⁢(R)2⁢∏y∈Y,r∈R(y+r)∏z∈ZPm⁢(z)⁢∏r∈RQm∗⁢(r)∏z∈Z(Fg,q(z)d⁢z2⁢π⁢i).\displaystyle\quad\times\oint_{(m\Gamma)^{d}}\frac{\Delta(Y)^{2}\Delta(R)^{2}% \prod_{y\in Y,r\in R}(y+r)}{\prod_{z\in Z}P_{m}(z)\prod_{r\in R}Q_{m}^{*}(r)}% \prod_{z\in Z}\left(F_{g,q}(z)\frac{dz}{2\pi i}\right).

This follows by applying Cauchy–Binet [4] to the two Cauchy moment factors, then expanding the diagonal summands in the contour formula row by row. For every equal-size pair, use the Cauchy determinant identity [6]

det((xi+yj)−1)i,j=1r=Δ⁢(x)⁢Δ⁢(y)∏i,j(xi+yj).\det\left((x_{i}+y_{j})^{-1}\right)_{i,j=1}^{r}=\frac{\Delta(x)\Delta(y)}{% \prod_{i,j}(x_{i}+y_{j})}.

Restoring the deleted fixed-grid factors uses

Δ⁢(Im∖S)⁢Δ⁢(Jm∖S)=Δ⁢(Im)⁢Δ⁢(Jm)⁢Δ⁢(S)2∏a∈SDm⁢(a).\Delta(I_{m}\setminus S)\Delta(J_{m}\setminus S)=\frac{\Delta(I_{m})\Delta(J_{% m})\Delta(S)^{2}}{\prod_{a\in S}D_{m}(a)}.

Each pinned index is therefore counted twice in a contour denominator and once in a frequency denominator. The three Cauchy factors give contour-contour, pinned-pinned, and frequency-frequency interactions with coefficient one, pinned-contour with coefficient two, and each remaining mixed interaction with coefficient one. Taking absolute values and scaling all positions by mm gives (6.2) and (6.4). The factors qaq^{a}, q−rq^{-r}, and qzq^{z} contribute only the one-body fields λ⁢ℜ⁡z\lambda\Re z and −λ⁢t-\lambda t in (6.5); the quadratic interaction coefficients are independent of qq.

The fixed-grid normalization is also explicit. Consecutive integer lists satisfy Δ⁢(Im)=∏j=1m−1j!\Delta(I_{m})=\prod_{j=1}^{m-1}j! and Δ⁢(Jm)=∏j=12⁢m−1j!\Delta(J_{m})=\prod_{j=1}^{2m-1}j!. Stirling’s formula [13] summed over these products gives

log⁡(Δ⁢(Im)2⁢Δ⁢(Jm))=3⁢m2⁢log⁡m+(2⁢log⁡2−9/2)⁢m2+O⁢(m⁢log⁡m).\log(\Delta(I_{m})^{2}\Delta(J_{m}))=3m^{2}\log m+(2\log 2-9/2)m^{2}+O(m\log m).

Equivalently, the fixed Vandermonde contributes C0=9/2−2⁢log⁡2C_{0}=9/2-2\log 2 to the negative logarithmic energy. The scaled Cauchy quotients cancel all m2⁢log⁡mm^{2}\log m terms; their remaining homogeneous factor is m−2⁢m−2⁢dm^{-2m-2d} before the contour differentials and m−2⁢m−dm^{-2m-d} after them. This accounts for the full quadratic normalization in (6.4).

6.1. The fixed variational problem and its affine parameter

Let η=κ+ν\eta=\kappa+\nu, where

0≤κ≤1E⁢d⁢x,ν≥0,supp⁡ν⊂Γ,|κ|+|ν|=1,0≤μ≤1[1/2,20]⁢d⁢t,|μ|=1.0\leq\kappa\leq 1_{E}\,dx,\quad\nu\geq 0,\quad\operatorname{supp}\nu\subset% \Gamma,\quad|\kappa|+|\nu|=1,\qquad 0\leq\mu\leq 1_{[1/2,20]}dt,\quad|\mu|=1.

Write μ−=(−id)#⁢μ\mu^{-}=(-\operatorname{id})_{\#}\mu for reflection onto the negative real axis. The set 𝒜\mathcal{A} of such pairs (η,μ)(\eta,\mu) is independent of qq. Define

A0⁢(z)=∫Elog⁡|z−x|⁢d⁢x+∫02log⁡|z−x|⁢d⁢x,B0⁢(t)=∫Elog⁡(t+x)⁢𝑑x+∫02log⁡(t+x)⁢𝑑x,A_{0}(z)=\int_{E}\log|z-x|\,dx+\int_{0}^{2}\log|z-x|\,dx,\qquad B_{0}(t)=\int_% {E}\log(t+x)\,dx+\int_{0}^{2}\log(t+x)\,dx,
ϕ2⁢(z)\displaystyle\phi_{2}(z) =(log⁡2)⁢ℜ⁡z+∫01/2log⁡|z+s|⁢d⁢s+12+12⁢log⁡2,\displaystyle=(\log 2)\Re z+\int_{0}^{1/2}\log|z+s|\,ds+\frac{1}{2}+\frac{1}{2% }\log 2,
ψ2⁢(t)\displaystyle\psi_{2}(t) =t⁢log⁡t−(t−1/2)⁢log⁡(t−1/2)+12⁢log⁡2−t⁢log⁡2.\displaystyle=t\log t-(t-1/2)\log(t-1/2)+\frac{1}{2}\log 2-t\log 2.

For measures on the corresponding reflected supports write

I⁢(σ,τ)=−∬log⁡|x−y|⁢d⁢σ⁢(x)⁢𝑑τ⁢(y).I(\sigma,\tau)=-\iint\log|x-y|\,d\sigma(x)d\tau(y).

The energy is

(6.3) ℰq⁢(η,μ)=\displaystyle\mathcal{E}_{q}(\eta,\mu)={} C0+∫(A0−ϕq)⁢𝑑η+∫(B0−ψq)⁢𝑑μ\displaystyle C_{0}+\int(A_{0}-\phi_{q})\,d\eta+\int(B_{0}-\psi_{q})\,d\mu
(6.4) +I⁢(η)+I⁢(μ)+I⁢(η,μ−),\displaystyle+I(\eta)+I(\mu)+I(\eta,\mu^{-}),

Here II is positive on zero-mass variations, while QlogQ_{\log} below uses the opposite, positive-logarithm convention. Also C0=9/2−2⁢log⁡2C_{0}=9/2-2\log 2 and, on writing q=2⁢eλq=2e^{\lambda},

(6.5) ϕq⁢(z)=ϕ2⁢(z)+λ⁢ℜ⁡z,ψq⁢(t)=ψ2⁢(t)−λ⁢t.\phi_{q}(z)=\phi_{2}(z)+\lambda\Re z,\qquad\psi_{q}(t)=\psi_{2}(t)-\lambda t.

The logarithmic integrals are understood in the following regularized sense: truncate at the logarithmic singularity, integrate the resulting bounded functions, and take the limit after replacing the coincident-cell term by the continuous primitive u⁢(log⁡|u|−1)u(\log|u|-1), with value 0 at u=0u=0. The measures used below have bounded densities and compact support, so this limit is finite. Substitution into (6.4) shows, for every fixed admissible pair,

(6.6) ℰλ⁢(η,μ)=ℰ0⁢(η,μ)+λ⁢(−∫ℜ⁡z⁢d⁢η⁢(z)+∫t⁢𝑑μ⁢(t)).\mathcal{E}_{\lambda}(\eta,\mu)=\mathcal{E}_{0}(\eta,\mu)+\lambda\left(-\int% \Re z\,d\eta(z)+\int t\,d\mu(t)\right).

Consequently

(6.7) α⁢(λ)=inf(η,μ)∈𝒜ℰλ⁢(η,μ)\alpha(\lambda)=\inf_{(\eta,\mu)\in\mathcal{A}}\mathcal{E}_{\lambda}(\eta,\mu)

is concave. Indeed, for 0≤θ≤10\leq\theta\leq 1, each fixed-pair energy at θ⁢λ0+(1−θ)⁢λ1\theta\lambda_{0}+(1-\theta)\lambda_{1} is the corresponding convex combination of its endpoint energies, and taking an infimum gives

α⁢(θ⁢λ0+(1−θ)⁢λ1)≥θ⁢α⁢(λ0)+(1−θ)⁢α⁢(λ1).\alpha(\theta\lambda_{0}+(1-\theta)\lambda_{1})\geq\theta\alpha(\lambda_{0})+(% 1-\theta)\alpha(\lambda_{1}).

Apply the shared quadratic-duality identity of Section C with quadratic part QP0⁢(η,μ)=I⁢(η)+I⁢(μ)+I⁢(η,μ−)Q_{\rm P0}(\eta,\mu)=I(\eta)+I(\mu)+I(\eta,\mu^{-}). Fix an admissible reference (η0,μ0)(\eta_{0},\mu_{0}) and put

Qlog=\displaystyle Q_{\log}={} ∬log⁡|z−w|⁢d⁢η0⁢(z)⁢𝑑η0⁢(w)+∬log⁡|t−s|⁢d⁢μ0⁢(t)⁢𝑑μ0⁢(s)\displaystyle\iint\log|z-w|\,d\eta_{0}(z)d\eta_{0}(w)+\iint\log|t-s|\,d\mu_{0}% (t)d\mu_{0}(s)
+∬log⁡|z+t|⁢d⁢η0⁢(z)⁢𝑑μ0⁢(t).\displaystyle+\iint\log|z+t|\,d\eta_{0}(z)d\mu_{0}(t).
QP0⁢(η0,μ0)=−Qlog,Wη=A0−ϕq−2⁢Lη0−Lμ0−,Wμ=B0−ψq−2⁢Lμ0−Lη0⁢(−t).Q_{\rm P0}(\eta_{0},\mu_{0})=-Q_{\log},\qquad W_{\eta}=A_{0}-\phi_{q}-2L_{\eta% _{0}}-L_{\mu_{0}^{-}},\qquad W_{\mu}=B_{0}-\psi_{q}-2L_{\mu_{0}}-L_{\eta_{0}}(% -t).

If Wη≥hηW_{\eta}\geq h_{\eta} on Γ\Gamma, set

P=∫E(hη−Wη)+⁢𝑑x,T=∫1/220(hμ−Wμ)+⁢𝑑t.P=\int_{E}(h_{\eta}-W_{\eta})_{+}\,dx,\qquad T=\int_{1/2}^{20}(h_{\mu}-W_{\mu}% )_{+}\,dt.

Then

(6.8) α⁢(λ)≥C0+Qlog+hη+hμ−P−T.\alpha(\lambda)\geq C_{0}+Q_{\log}+h_{\eta}+h_{\mu}-P-T.

For σ=η−η0\sigma=\eta-\eta_{0} and τ=μ−−μ0−\tau=\mu^{-}-\mu_{0}^{-}, the shared identity has remainder

I⁢(σ)+I⁢(τ)+I⁢(σ,τ)=12⁢I⁢(σ)+12⁢I⁢(τ)+12⁢I⁢(σ+τ)≥0,I(\sigma)+I(\tau)+I(\sigma,\tau)=\tfrac{1}{2}I(\sigma)+\tfrac{1}{2}I(\tau)+% \tfrac{1}{2}I(\sigma+\tau)\geq 0,

where I⁢(ρ)=−∬log⁡|x−y|⁢d⁢ρ⁢(x)⁢𝑑ρ⁢(y)I(\rho)=-\iint\log|x-y|\,d\rho(x)d\rho(y) is nonnegative for zero-mass signed measures. The density constraints then give ∫Wη⁢𝑑η≥hη−P\int W_{\eta}d\eta\geq h_{\eta}-P and ∫Wμ⁢𝑑μ≥hμ−T\int W_{\mu}d\mu\geq h_{\mu}-T, proving (6.8).

6.2. Finite configurations and cell estimates

For a selected pinned set S⊂ImS\subset I_{m} and a frequency set RR, define

κS\displaystyle\kappa_{S} =∑i∈S𝟏[i/m,(i+1)/m)⁢d⁢x,\displaystyle=\sum_{i\in S}\mathbf{1}_{[i/m,(i+1)/m)}dx, μR\displaystyle\mu_{R} =∑r∈R𝟏[(r−1)/m,r/m)⁢d⁢t,\displaystyle=\sum_{r\in R}\mathbf{1}_{[(r-1)/m,r/m)}dt,
νδ\displaystyle\nu_{\delta} =1m⁢∑a=1dσza/m,δ,\displaystyle=\frac{1}{m}\sum_{a=1}^{d}\sigma_{z_{a}/m,\delta}, δ\displaystyle\delta =m−2.\displaystyle=m^{-2}.

Here σz,δ\sigma_{z,\delta} is probability arclength on the radius-δ\delta circle centered at zz. Put ζa=za/m∈Γ\zeta_{a}=z_{a}/m\in\Gamma. Thus all logarithms in the continuum energy are in scaled coordinates; the powers of mm arising from the change from zaz_{a} to ζa\zeta_{a} have already been included in the fixed Vandermonde normalization in the cell estimate. The first two measures have density at most one, masses |S|/m|S|/m and one, and the first frequency cell begins at 1/21/2. Circle averaging gives

(6.9) ∑a≠blog⁡|ζa−ζb|≤m2⁢∬log⁡|z−w|⁢d⁢νδ⁢(z)⁢𝑑νδ⁢(w)+2⁢d⁢log⁡m.\sum_{a\neq b}\log|\zeta_{a}-\zeta_{b}|\leq m^{2}\iint\log|z-w|\,d\nu_{\delta}% (z)d\nu_{\delta}(w)+2d\log m.

The fixed-grid and reflected-frequency logarithmic potentials are harmonic on the smoothing disks. The contour field is subharmonic, including across the zero segment of Fg,qF_{g,q}. Thus smoothing has no additional field error; the explicit 2⁢d⁢log⁡m2d\log m is the full smoothing loss.

The exact real-cell estimates used in the envelope are listed here to make the finite-size accounting reproducible. For nn distinct lattice sites, the cell self-energy inequality is

∑a≠blog⁡|xa−xb|≤m2⁢∬log⁡|x−y|⁢d⁢ρ⁢(x)⁢𝑑ρ⁢(y)+n⁢(log⁡m+log⁡(2⁢π)),\sum_{a\neq b}\log|x_{a}-x_{b}|\leq m^{2}\iint\log|x-y|\,d\rho(x)d\rho(y)+n(% \log m+\log(2\pi)),

where ρ\rho is the union of their length-1/m1/m cells. To see the constant, write

ed=log⁡d−∫01∫01log⁡|d+u−v|⁢d⁢u⁢d⁢v.e_{d}=\log d-\int_{0}^{1}\!\int_{0}^{1}\log|d+u-v|\,du\,dv.

Then e1=3/2−2⁢log⁡2e_{1}=3/2-2\log 2 and for d≥2d\geq 2,

ed=∑j≥11j⁢(2⁢j+1)⁢(2⁢j+2)⁢d2⁢j≤112⁢d⁢(d−1),∑d≥1ed=12⁢log⁡(2⁢π)−34.e_{d}=\sum_{j\geq 1}\frac{1}{j(2j+1)(2j+2)d^{2j}}\leq\frac{1}{12d(d-1)},\qquad% \sum_{d\geq 1}e_{d}=\tfrac{1}{2}\log(2\pi)-\tfrac{3}{4}.

Indeed, for d≥2d\geq 2 expand log⁡(1+(u−v)/d)\log(1+(u-v)/d) in its absolutely convergent power series and integrate term by term; the even moments ∫01∫01(u−v)2⁢j⁢𝑑u⁢𝑑v=2/((2⁢j+1)⁢(2⁢j+2))\int_{0}^{1}\!\int_{0}^{1}(u-v)^{2j}\,du\,dv=2/((2j+1)(2j+2)) give the displayed series, while the d=1d=1 integral is elementary. Summing the same identity from d=1d=1 to MM, exchanging the positive series, and using Stirling’s Wallis limit [13] log⁡M!=(M+12)⁢log⁡M−M+12⁢log⁡(2⁢π)+o⁢(1)\log M!=(M+\tfrac{1}{2})\log M-M+\tfrac{1}{2}\log(2\pi)+o(1) gives the displayed infinite sum. Thus no numerical cell constant is being imported. There are at most two sites at each distance from a fixed site. This proves the displayed inequality by summing the self-cell and pair-cell errors. Applied to the selected pinned and frequency sites and to the fixed Vandermonde, it contributes 4⁢m⁢(log⁡m+log⁡(2⁢π))4m(\log m+\log(2\pi)).

The remaining one-body and mixed-cell bounds are as follows. Binomial entropy gives

log⁡Ui⁢(q)≤m⁢ϕq⁢(i/m),log⁡wr,q≤m⁢ψq⁢(r/m).\log U_{i}(q)\leq m\phi_{q}(i/m),\qquad\log w_{r,q}\leq m\psi_{q}(r/m).

The exact cell corrections from the affine parameter are −λ⁢m/2-\lambda m/2 for frequencies and −λ⁢|S|/2-\lambda|S|/2 for pinned cells. For the base-22 frequency field,

ψ2′⁢(t)=log⁡tt−1/2−log⁡2,∫1/21(ψ2′⁢(t))+⁢𝑑t=12⁢log⁡2.\psi_{2}^{\prime}(t)=\log\frac{t}{t-1/2}-\log 2,\qquad\int_{1/2}^{1}(\psi_{2}^% {\prime}(t))_{+}\,dt=\tfrac{1}{2}\log 2.

Summing endpoint-to-cell differences over disjoint frequency cells costs at most (m/2)⁢log⁡2(m/2)\log 2. Monotone quadrature for the fixed-grid field gives, for t≥1/2t\geq 1/2,

0≤m⁢B0⁢(t)−∑i∈Imlog⁡(t+i/m)−∑j∈Jmlog⁡(t+j/m)≤log⁡(35/3).0\leq mB_{0}(t)-\sum_{i\in I_{m}}\log(t+i/m)-\sum_{j\in J_{m}}\log(t+j/m)\leq% \log(35/3).

Thus the frequency one-body cost is at most m⁢(log⁡(35/3)+12⁢log⁡2)−λ⁢m/2m(\log(35/3)+\tfrac{1}{2}\log 2)-\lambda m/2.

For the pinned denominator, take NN consecutive sites starting at aa and containing ii, with nL=i−an_{L}=i-a and nR=a+N−1−in_{R}=a+N-1-i. Comparing the omitted site product on the two sides of ii with its cell integral gives

log⁡(nL!⁢nR!)−(N−1)⁢log⁡m−m⁢∫a/m(a+N)/mlog⁡|i/m−y|⁢d⁢y≥log⁡mnR+1.\log(n_{L}!n_{R}!)-(N-1)\log m-m\int_{a/m}^{(a+N)/m}\log|i/m-y|\,dy\geq\log% \frac{m}{n_{R}+1}.

This follows from monotone logarithmic sums and nR⁢log⁡(1+1/nR)≤1n_{R}\log(1+1/n_{R})\leq 1; the zero case is direct. The ImI_{m} contribution is nonnegative and the JmJ_{m} contribution is at least −log⁡2-\log 2. Direct integration of the explicit derivatives gives ∫E|(ϕ2−A0)′|≤log⁡6+2⁢log⁡2+log⁡7=log⁡168\int_{E}|(\phi_{2}-A_{0})^{\prime}|\leq\log 6+2\log 2+\log 7=\log 168. Consequently pinned quadrature costs at most m⁢log⁡336m\log 336. Its affine correction is −λ⁢|S|/2-\lambda|S|/2, since the linear-field integral on each cell is centered one half-cell to the right of the selected lattice point. For an exact bookkeeping check, q/2−log⁡qq/2-\log q is increasing and positive on [2,∞)[2,\infty), hence (log⁡log⁡q)+≤λ(\log\log q)_{+}\leq\lambda. Therefore the diagonal and cell-shift contribution satisfies

|S|⁢(log⁡log⁡q)+−λ2⁢(|S|+m)≤−λ2⁢(m−|S|)≤0.|S|(\log\log q)_{+}-\frac{\lambda}{2}(|S|+m)\leq-\frac{\lambda}{2}(m-|S|)\leq 0.

The displayed pointwise estimate keeps the positive term and drops these favorable shifts, so it remains valid without relying on this cancellation.

The ellipse clearances are

d+=dist⁡(Γ,[0,2])=751/5000,d−=dist⁡(Γ,(−∞,−1/2])=1749/5000.d_{+}=\operatorname{dist}(\Gamma,[0,2])=751/5000,\qquad d_{-}=\operatorname{% dist}(\Gamma,(-\infty,-1/2])=1749/5000.

They follow by minimizing the squared distance as a quadratic in cos⁡u\cos u on the ellipse parametrization. The pinned-contour displacement costs m/d+m/d_{+}, the fixed contour denominators cost 3⁢m/(2⁢d+)3m/(2d_{+}), and the contour-frequency displacement costs m/(2⁢d−)m/(2d_{-}). The pinned-frequency cell displacement is centered; Taylor’s inequality, with i/m+r/m≥3/4i/m+r/m\geq 3/4 and cell width 1/m≤1/41/m\leq 1/4, bounds its total loss by 1/31/3. Together these contributions are at most

m⁢(52⁢d++12⁢d−)+13.m\left(\frac{5}{2d_{+}}+\frac{1}{2d_{-}}\right)+\frac{1}{3}.

Set Tδ={z:dist⁡(z,Γ)≤δ}T_{\delta}=\{z:\operatorname{dist}(z,\Gamma)\leq\delta\}, with the tube radius δ\delta used in the transfer argument below. For the finite contour product the required inequality is one-sided. Fix z∈Tδz\in T_{\delta}, put ζ=m⁢z\zeta=mz, r=−ℜ⁡ζr=-\Re\zeta, b=ℑ⁡ζb=\Im\zeta, and f⁢(u)=log⁡|ζ+u|f(u)=\log|\zeta+u|. Then

f′⁢(u)=u−r(u−r)2+b2,f^{\prime}(u)=\frac{u-r}{(u-r)^{2}+b^{2}},

so ff decreases to rr and increases after rr. Put H=max⁡(f,0)H=\max(f,0). The negative part of ff is supported near rr; after translating rr and using ∫−11(log⁡|u|)−⁢𝑑u=2\int_{-1}^{1}(\log|u|)_{-}\,du=2, its integral over every unit cell meeting rr is at most 22. On each of the two monotone pieces the right-endpoint quadrature error for HH is nonpositive on the decreasing piece and nonnegative on the increasing piece. The positive contribution is bounded by the variation on the increasing piece. The sampled endpoint values are bounded by log⁡(4⁢(g+1))\log(4(g+1)) near the turning cell and by log⁡(6⁢(g+1))\log(6(g+1)) at the right endpoint, so this variation is at most log⁡(6⁢(g+1))\log(6(g+1)). Thus the complete discrepancy satisfies

∑k=0g−1f⁢(k+1)−∫0gf⁢(u)⁢𝑑u≤2+log⁡(6⁢(g+1)).\sum_{k=0}^{g-1}f(k+1)-\int_{0}^{g}f(u)\,du\leq 2+\log(6(g+1)).

This is the bounded-variation estimate for the truncated function HH; it also covers the cases where the zero of ff lies outside [0,g][0,g]. We retain the looser uniform quantity

βm=4⁢log⁡(g+1)+9+10⁢log⁡2\beta_{m}=4\log(g+1)+9+10\log 2

below. Restoring the factors log⁡m\log m gives the cell integral in the contour-product estimate. Thus, for every z∈Tδz\in T_{\delta},

(6.10) log⁡|Fg,q⁢(m⁢z)|≤m⁢ϕq⁢(z)+βm.\log|F_{g,q}(mz)|\leq m\phi_{q}(z)+\beta_{m}.

The scalar factor qm⁢zq^{mz} is exactly the affine field term and adds no discrepancy. No lower bound for this discrepancy is used. Since g+1≤mg+1\leq m for m≥8m\geq 8, the contour and circle errors together contribute 2⁢m⁢log⁡m+m⁢βm2m\log m+m\beta_{m}.

Combining the preceding terms with the fixed Vandermonde normalization and discarding favorable powers of mm gives, for every configuration,

log⁡Qm,q⁢(S,R,Z)≤−m2⁢ℰq⁢(κS+νδ,μR)+10⁢m⁢log⁡m+c∗⁢m+13+|S|⁢log⁡log⁡q,\log Q_{m,q}(S,R,Z)\leq-m^{2}\mathcal{E}_{q}(\kappa_{S}+\nu_{\delta},\mu_{R})+% 10m\log m+c_{*}m+\frac{1}{3}+|S|\log\log q,

where the real-cell constant is

c∗=\displaystyle c_{*}={} 4⁢log⁡(2⁢π)+9+212⁢log⁡2+log⁡336+log⁡(35/3)+52⁢d++12⁢d−\displaystyle 4\log(2\pi)+9+\frac{21}{2}\log 2+\log 336+\log(35/3)+\frac{5}{2d% _{+}}+\frac{1}{2d_{-}}
<\displaystyle<{} 49.978.\displaystyle 49.978.

The displayed logarithm bounds can be checked with the rational series

log⁡x=2⁢∑j=0Nu2⁢j+12⁢j+1+RN,0<RN<2⁢u2⁢N+3(2⁢N+3)⁢(1−u2),u=x−1x+1.\log x=2\sum_{j=0}^{N}\frac{u^{2j+1}}{2j+1}+R_{N},\qquad 0<R_{N}<\frac{2u^{2N+% 3}}{(2N+3)(1-u^{2})},\quad u=\frac{x-1}{x+1}.

For x=710/113x=710/113 use N=50N=50; for x=2,21/16,35/24,39/32x=2,21/16,35/24,39/32 use N=16N=16. The rational series gives

log⁡(710/113)<1.83787716,log⁡2<0.69314719,log⁡(21/16)<0.27193372,\log(710/113)<1.83787716,\quad\log 2<0.69314719,\quad\log(21/16)<0.27193372,
log⁡(35/24)<0.37729424,log⁡(39/32)<0.19782575.\log(35/24)<0.37729424,\qquad\log(39/32)<0.19782575.

The classical rational bound π<355/113\pi<355/113 therefore gives log⁡(2⁢π)<1.83787716\log(2\pi)<1.83787716; hence log⁡336<8⁢(0.69314719)+0.27193372\log 336<8(0.69314719)+0.27193372 and log⁡(35/3)<3⁢(0.69314719)+0.37729424\log(35/3)<3(0.69314719)+0.37729424. Substitution of the exact rational d+=751/5000d_{+}=751/5000 and d−=1749/5000d_{-}=1749/5000 gives c∗<49.977264<49.978c_{*}<49.977264<49.978 and c∗+log⁡39+1+A<55.920<56c_{*}+\log 39+1+A<55.920<56. This is the base-22 cell constant; the qq-dependent cell shifts above are favorable. The only qq-dependent finite factor not absorbed by the affine energy is the diagonal multiplier (log⁡q)|S|(\log q)^{|S|}. In the pointwise envelope it appears as the exact term |S|⁢log⁡log⁡q|S|\log\log q. At q=2q=2 this term is negative, so the base-22 estimate omits that favorable factor; whenever an upper bound uniform in qq is taken below, it is replaced by |S|⁢(log⁡log⁡q)+|S|(\log\log q)_{+}. Uniformly for 2≤q≤112\leq q\leq 11,

log⁡q<3,0<log⁡q<3<5,log⁡(log⁡q)<log⁡3<2,\log q<3,\qquad 0<\log q<3<5,\qquad\log(\log q)<\log 3<2,

so |S|⁢(log⁡log⁡q)+<2⁢m|S|(\log\log q)_{+}<2m. For all bases we therefore replace 56⁢m56m by at most 58⁢m58m; this finite correction is O⁢(m)O(m) and does not change the limiting energy rate.

6.3. Tube transfer, frequency tail, and summation

Let DD be the interior of the ellipse. For zz inside DD use its interior harmonic measure ωz\omega_{z} on Γ\Gamma; outside DD use exterior harmonic measure of total mass one; on Γ\Gamma use δz\delta_{z}. Let WW be the exterior inverse of 𝒥⁢(w)=ξ+c⁢w+d/w\mathcal{J}(w)=\xi+cw+d/w, where c=(A+B)/2c=(A+B)/2 and d=(A−B)/2d=(A-B)/2. Define e⁢(z)=0e(z)=0 in DD and e⁢(z)=log⁡|W⁢(z)|e(z)=\log|W(z)| outside. The factorization 𝒥⁢(w1)−𝒥⁢(w2)=(w1−w2)⁢(c−d/(w1⁢w2))\mathcal{J}(w_{1})-\mathcal{J}(w_{2})=(w_{1}-w_{2})(c-d/(w_{1}w_{2})) and the Green identity imply

∫K0⁢(x,y)⁢𝑑ωz⁢(y)≤K0⁢(x,z)+e⁢(z),I⁢(ωz,ωw)≤K0⁢(z,w)+e⁢(z)+e⁢(w),\int K_{0}(x,y)\,d\omega_{z}(y)\leq K_{0}(x,z)+e(z),\qquad I(\omega_{z},\omega% _{w})\leq K_{0}(z,w)+e(z)+e(w),

where K0=−log|⋅|K_{0}=-\log|\cdot| and II denotes its mutual energy. The interior deficit is the Green function of DD; the exterior deficit is the nonnegative disk Green function; the cross-boundary deficit is zero. For w=ρ⁢ei⁢uw=\rho e^{iu}, ρ≥1\rho\geq 1, the equipotential |W⁢(z)|=ρ|W(z)|=\rho is the confocal ellipse

Γρ:z=ξ+(c⁢ρ+d/ρ)⁢cos⁡u+i⁢(c⁢ρ−d/ρ)⁢sin⁡u.\Gamma_{\rho}:z=\xi+(c\rho+d/\rho)\cos u+i(c\rho-d/\rho)\sin u.

It equals Γ\Gamma at ρ=1\rho=1. If z=𝒥⁢(w)z=\mathcal{J}(w) and ζ=𝒥⁢(v)∈Γ\zeta=\mathcal{J}(v)\in\Gamma, |v|=1|v|=1, the exact factorization gives

|z−ζ|=|w−v|⁢|c−dw⁢v|≥(ρ−1)⁢(c−d/ρ)≥B⁢(ρ−1).|z-\zeta|=|w-v|\left|c-\frac{d}{wv}\right|\geq(\rho-1)(c-d/\rho)\geq B(\rho-1).

Taking the infimum over ζ\zeta and using log⁡ρ≤ρ−1\log\rho\leq\rho-1 proves

e⁢(z)≤dist⁡(z,Γ)/B≤δ/B(z∉D,z∈Tδ).e(z)\leq\operatorname{dist}(z,\Gamma)/B\leq\delta/B\qquad(z\notin D,\ z\in T_{% \delta}).

For x∈[0,2]x\in[0,2], set χ⁢(z)=1−(ℜ⁡z−ξ)2/A2−(ℑ⁡z)2/B2\chi(z)=1-(\Re z-\xi)^{2}/A^{2}-(\Im z)^{2}/B^{2}. On DD, |∇χ|≤2/B|\nabla\chi|\leq 2/B, while χ⁢(x)>1/5\chi(x)>1/5. The level curve χ=1/8\chi=1/8 is more than 1/321/32 from [0,2][0,2], so the Green function there is at most log⁡160<6\log 160<6. The barrier 48⁢χ48\chi on the collar gives

gD⁢(z,x)≤96⁢δ/B(z∈D∩Tδ,x∈[0,2]).g_{D}(z,x)\leq 96\delta/B\qquad(z\in D\cap T_{\delta},\ x\in[0,2]).

Since A0A_{0} has source mass three and λ⁢ℜ⁡z\lambda\Re z is harmonic, the interior field-sweep loss for A0−ϕqA_{0}-\phi_{q} is at most 288⁢δ/B288\delta/B. The term −V-V is favorable in this estimate: VV is subharmonic, with distributional Laplacian 2⁢π2\pi times the source measure on [−1/2,0][-1/2,0], so its harmonic sweep is at least its interior value and the −V-V contribution can be dropped from an upper bound. For exterior z=𝒥⁢(w)z=\mathcal{J}(w), the swept mean coordinate is ξ+c/w¯+d/w\xi+c/\overline{w}+d/w, within (A+B)⁢δ/B(A+B)\delta/B of zz. For the base-22 terms the source bound is [1/2+(A+B)⁢log⁡2]⁢δ/B<3⁢δ/B[1/2+(A+B)\log 2]\delta/B<3\delta/B: A0A_{0} changes by exactly −3⁢e⁢(z)-3e(z), and the remaining coordinate displacement is at most (A+B)⁢δ/B(A+B)\delta/B. The additional affine term is at most λ⁢(A+B)⁢δ/B<6⁢δ/B\lambda(A+B)\delta/B<6\delta/B because λ=log⁡(q/2)<2\lambda=\log(q/2)<2 and A+B<3A+B<3.

The logarithmic source in ϕq\phi_{q} needs a separate collar estimate. Put

V⁢(z)=∫01/2log⁡|z+s|⁢d⁢s.V(z)=\int_{0}^{1/2}\log|z+s|\,ds.

For 0<δ≤1/640<\delta\leq 1/64 and an exterior point with dist⁡(z,Γ)≤δ\operatorname{dist}(z,\Gamma)\leq\delta, the explicit primitive

V⁢(z)=ℜ⁡((z+1/2)⁢Log⁡(z+1/2)−z⁢Log⁡z−1/2)V(z)=\Re\bigl{(}(z+1/2)\operatorname{Log}(z+1/2)-z\operatorname{Log}z-1/2\bigr% {)}

on either side of the source segment gives

∇V⁢(z)=Log⁡(z+1/2)−Log⁡z.\nabla V(z)=\operatorname{Log}(z+1/2)-\operatorname{Log}z.

For z=ξ+A⁢cos⁡u+i⁢B⁢sin⁡uz=\xi+A\cos u+iB\sin u on Γ\Gamma, minimizing |z|2|z|^{2} gives its minimum at u=πu=\pi, namely ξ−A=751/5000\xi-A=751/5000; the derivative has no other critical point because A⁢ξ>|A2−B2|A\xi>|A^{2}-B^{2}|. The disk of this radius about 0 lies inside the ellipse, so every exterior point satisfies |z|≥751/5000|z|\geq 751/5000. For the radial comparison path, h≤δ/Bh\leq\delta/B and

|𝒥⁢((1+h)⁢ei⁢u)−𝒥⁢(ei⁢u)|≤(c+d)⁢h=A⁢h≤AB⁢δ=1278311450⁢δ<1.117⁢δ.|\mathcal{J}((1+h)e^{iu})-\mathcal{J}(e^{iu})|\leq(c+d)h=Ah\leq\frac{A}{B}% \delta=\frac{12783}{11450}\delta<1.117\delta.

This is about 1.116⁢δ1.116\delta and is less than 0.020.02 when δ≤1/64\delta\leq 1/64. Thus all points used in the estimate have ℜ⁡z≥−751/5000−(12783/11450)/64>−1/4\Re z\geq-751/5000-(12783/11450)/64>-1/4. Therefore

|z+1/2||z|≤1+12⁢|z|≤1+2500751=3251751<4.33,|arg⁡(z+1/2)−arg⁡z|≤π.\frac{|z+1/2|}{|z|}\leq 1+\frac{1}{2|z|}\leq 1+\frac{2500}{751}=\frac{3251}{75% 1}<4.33,\qquad|\arg(z+1/2)-\arg z|\leq\pi.

Since |z+1/2|2−|z|2=ℜ⁡z+1/4>0|z+1/2|^{2}-|z|^{2}=\Re z+1/4>0, the ratio is at least one, and the modulus term in the difference of logarithms is at most log⁡(4.33)\log(4.33). The angle difference is at most π\pi because the two points lie on the same horizontal line. Also e3/2>4.33e^{3/2}>4.33 by the first six terms of its positive series, so log⁡(4.33)<3/2\log(4.33)<3/2. Thus, on both sides of the cut,

|∇V⁢(z)|≤(3/2)2+(22/7)2<3.72.|\nabla V(z)|\leq\sqrt{(3/2)^{2}+(22/7)^{2}}<3.72.

At the contact point z0=ξ−A=−751/5000z_{0}=\xi-A=-751/5000 the classical gradient is not defined, but these are the bounded one-sided traces and they give the required Lipschitz bound across the smooth ellipse and the source cut. The Joukowski boundary parametrization has speed at most 4/34/3, so its pullback is 66-Lipschitz. If the exterior pole is w=ρ⁢ei⁢uw=\rho e^{iu}, write ρ=1+h\rho=1+h. The elementary estimate

∫−ππ|t|⁢P1+h⁢(t)⁢d⁢t2⁢π≤3⁢π⁢h8⁢log⁡(1+4/h2)\int_{-\pi}^{\pi}|t|P_{1+h}(t)\,\frac{dt}{2\pi}\leq\frac{3\pi h}{8}\log(1+4/h^% {2})

is used for 0<h≤10<h\leq 1 and follows from 1−cos⁡t≥2⁢t2/π21-\cos t\geq 2t^{2}/\pi^{2}. In the present collar h≤δ/B≤25/1832<1h\leq\delta/B\leq 25/1832<1, so this is the required range. Since dist⁡(𝒥⁢(w),Γ)≥B⁢h\operatorname{dist}(\mathcal{J}(w),\Gamma)\geq Bh and δ≤1/64\delta\leq 1/64, these bounds imply

|∫ΓV⁢(ζ)⁢𝑑ωz⁢(ζ)−V⁢(z)|≤20⁢δ⁢log⁡(1/δ).\left|\int_{\Gamma}V(\zeta)\,d\omega_{z}(\zeta)-V(z)\right|\leq 20\delta\log(1% /\delta).

Thus the exterior field loss is at most 9⁢δ/B+20⁢δ⁢log⁡(1/δ)9\delta/B+20\delta\log(1/\delta). Combining this with the interior bound gives a uniform field loss at most 288⁢δ/B+20⁢δ⁢log⁡(1/δ)288\delta/B+20\delta\log(1/\delta).

The three interaction terms change by at most 3⁢b3b, where b=∫e⁢𝑑ν≤|ν|⁢δ/Bb=\int e\,d\nu\leq|\nu|\delta/B. Since |ν|≤1|\nu|\leq 1, their total loss is at most 3⁢δ/B3\delta/B. Consequently the full transfer cost is at most 291⁢δ/B+20⁢δ⁢log⁡(1/δ)<300⁢δ+20⁢δ⁢log⁡(1/δ)291\delta/B+20\delta\log(1/\delta)<300\delta+20\delta\log(1/\delta) because B=229/200>1B=229/200>1. Thus

ℰq⁢(κ+νδ,μ)≥α⁢(λ)−300⁢δ−20⁢δ⁢log⁡(1/δ),291B<300.\mathcal{E}_{q}(\kappa+\nu_{\delta},\mu)\geq\alpha(\lambda)-300\delta-20\delta% \log(1/\delta),\qquad\frac{291}{B}<300.

The dual problem is posed on the printed support interval [1/2,20][1/2,20]. The frequency-cutoff argument below first replaces the full frequency sum by the range R⊂{g+1,…,20⁢m}R\subset\{g+1,\ldots,20m\}, with a positive multiplicative tail factor. Hence every finite configuration used in the variational bound has its frequency measure in this compact interval; the omitted tail is accounted for separately in (6.3).

For completeness, the unbounded frequency sum is reduced to a finite one before counting configurations. For H≥g+1H\geq g+1, define

Em,q⁢(H)=∑S⊂Im1d!⁢∫(m⁢Γ)d∑R⊂{g+1,…,H}|R|=mQm,q⁢(S,R,Z)⁢∏z∈Z|d⁢z|2⁢π.E_{m,q}(H)=\sum_{S\subset I_{m}}\frac{1}{d!}\int_{(m\Gamma)^{d}}\sum_{\begin{% subarray}{c}R\subset\{g+1,\ldots,H\}\\ |R|=m\end{subarray}}Q_{m,q}(S,R,Z)\prod_{z\in Z}\frac{|dz|}{2\pi}.

The Cauchy–Binet expansion [4] gives |Gm,q|≤Em,q⁢(∞)|G_{m,q}|\leq E_{m,q}(\infty). For fixed S,ZS,Z, its frequency-dependent factor is

fq⁢(R)=∏r∈Rwr,q⁢Δ⁢(R)2⁢∏r∈R,z∈Z|r+z|∏r∈R,i∈Im(r+i)⁢∏r∈R,j∈Jm∖S(r+j).f_{q}(R)=\frac{\prod_{r\in R}w_{r,q}\,\Delta(R)^{2}\prod_{r\in R,z\in Z}|r+z|}% {\prod_{r\in R,i\in I_{m}}(r+i)\prod_{r\in R,j\in J_{m}\setminus S}(r+j)}.

If r=max⁡R>20⁢mr=\max R>20m, replace rr by the least missing s∈{g+1,…,g+m}s\in\{g+1,\ldots,g+m\}, so s≤3⁢m/2s\leq 3m/2. The exact ratio of the frequency weights, both frequency Vandermonde factors, and all contour-frequency factors gives

fq⁢(R)fq⁢(R′)≤12500m⁢m24⁢r2⁢wr,2.\frac{f_{q}(R)}{f_{q}(R^{\prime})}\leq 12500^{m}\frac{m^{2}}{4r^{2}}w_{r,2}.

For the constant, at most two integers lie at each distance from ss, so

Cancel the common factors in the two Cauchy determinants. The two frequency Vandermonde ratios contribute the squared products of distances from rr and ss; each contour-frequency factor is bounded by the corresponding ratio involving r+gr+g and s+gs+g, and the fixed-grid factors are bounded by 5m5^{m}. The explicit denominator bounds s+i≤11⁢m/4s+i\leq 11m/4, s+j≤7⁢m/2s+j\leq 7m/2, and ellipse bounds ℜ⁡z>−m/6\Re z>-m/6, |z|<5⁢m/2|z|<5m/2 give

For r>sr>s, wr,q/ws,q≤wr,2/ws,2w_{r,q}/w_{s,q}\leq w_{r,2}/w_{s,2} and ws,2≥2−3⁢m/2w_{s,2}\geq 2^{-3m/2} because s≤3⁢m/2s\leq 3m/2 and (s−1g)≥1\binom{s-1}{g}\geq 1. Substituting this and e<3e<3 into the last display gives the asserted 12500m⁢m2⁢wr,2/(4⁢r2)12500^{m}m^{2}w_{r,2}/(4r^{2}) bound. This is the full constant calculation; it does not require an estimate for ws,qw_{s,q}. The exact base comparison is

wr,q/ws,qwr,2/ws,2=(2q)r−s≤1.\frac{w_{r,q}/w_{s,q}}{w_{r,2}/w_{s,2}}=\left(\frac{2}{q}\right)^{r-s}\leq 1.

ϑm=m1600⁢12500m⁢∑r>20⁢mwr,2.\vartheta_{m}=\frac{m}{1600}12500^{m}\sum_{r>20m}w_{r,2}.

Indeed, the replacement map has at most mm preimages for each pair (R′,r)(R^{\prime},r), and m2/(4⁢r2)<1/1600m^{2}/(4r^{2})<1/1600 when r>20⁢mr>20m. For t=15/8t=15/8,

∑r>20⁢mwr,2≤(8/15)20⁢m⁢∑r≥g+1wr,2⁢(15/8)r=(8/15)20⁢m⁢15g+1.\sum_{r>20m}w_{r,2}\leq(8/15)^{20m}\sum_{r\geq g+1}w_{r,2}(15/8)^{r}=(8/15)^{2% 0m}15^{g+1}.

Since g=m/2g=m/2 and 12500⁢15<5000012500\sqrt{15}<50000, this gives

ϑm≤15⁢m1600⁢[50000⁢(8/15)20]m<3320⁢2−m<12.\vartheta_{m}\leq\frac{15m}{1600}\left[50000(8/15)^{20}\right]^{m}<\frac{3}{32% 0}2^{-m}<\frac{1}{2}.

The strict inequality uses 200000⋅820<1520200000\cdot 8^{20}<15^{20} and m⁢2−m≤1m2^{-m}\leq 1. If ZMZ_{M} denotes the finite frequency sum through MM, the replacement map gives ZM−Z20⁢m≤ϑm⁢ZMZ_{M}-Z_{20m}\leq\vartheta_{m}Z_{M}. Hence ZM≤(1−ϑm)−1⁢Z20⁢m≤(1+2⁢ϑm)⁢Z20⁢mZ_{M}\leq(1-\vartheta_{m})^{-1}Z_{20m}\leq(1+2\vartheta_{m})Z_{20m}.

2⁢ϑm<3160⁢2−m.2\vartheta_{m}<\frac{3}{160}2^{-m}.

Monotone convergence as M→∞M\to\infty now proves

Em⁢(∞)≤(1+3160⁢2−m)⁢Em⁢(20⁢m).E_{m}(\infty)\leq\left(1+\frac{3}{160}2^{-m}\right)E_{m}(20m).

∎

There are 2m2^{m} pinned subsets and at most (39⁢m/2m)\binom{39m/2}{m} retained frequency sets. The normalized contour length is at most m⁢AmA, hence (m⁢A)d/d!≤em⁢A(mA)^{d}/d!\leq e^{mA}. Using c∗<49.979c_{*}<49.979 and c∗+log⁡39+1+A<56c_{*}+\log 39+1+A<56, the finite configuration bound, the tube transfer with δ=m−2\delta=m^{-2}, and the tail factor imply the following.

Lemma 6.1 (Uniform smoothing bound).

For every integer q∈{2,…,11}q\in\{2,\ldots,11\} and every m∈4⁢ℕm\in 4\mathbb{N}, m≥8m\geq 8,

(6.11) log⁡|Gm,q⁢(Li2⁡(1/q))|≤−α⁢(log⁡(q/2))⁢m2+10⁢m⁢log⁡m+58⁢m+301+40⁢log⁡m.\log|G_{m,q}(\operatorname{Li}_{2}(1/q))|\leq-\alpha(\log(q/2))m^{2}+10m\log m% +58m+301+40\log m.

The frequency quantifier before replacement is the full set R⊂{g+1,g+2,…}R\subset\{g+1,g+2,\ldots\} of cardinality mm. The constant 5858 is uniform in qq; the constant 301301 includes the tube cost 300300, the real-cell remainder 1/31/3, and the exponentially small frequency-tail factor. The additional 40⁢log⁡m40\log m is the explicit logarithmic collar cost.

Proof.

For each finite configuration the cell measures above are admissible in the m−2m^{-2} tube problem. Tube transfer bounds their energy below by α⁢(λ)−300⁢m−2−40⁢m−2⁢log⁡m\alpha(\lambda)-300m^{-2}-40m^{-2}\log m. Inserting this into the pointwise determinant envelope gives a 300+40⁢log⁡m300+40\log m additive loss. Summing the 2m2^{m} pinned choices, the (39⁢m/2m)\binom{39m/2}{m} retained frequency choices, and the contour integral adds at most (log⁡39+1+A)⁢m(\log 39+1+A)m beyond c∗⁢mc_{*}m. The first contribution is strictly less than 56⁢m56m by the displayed c∗+log⁡39+1+A<56c_{*}+\log 39+1+A<56; the extra diagonal factor is strictly less than e2⁢me^{2m}. Hence the coefficient of mm is strictly less than 56+2=5856+2=58. The cell remainder is 1/31/3. For m≥8m\geq 8 the tail factor obeys

log⁡(1+3160⁢2−m)≤3160⁢2−m≤340960,\log\left(1+\frac{3}{160}2^{-m}\right)\leq\frac{3}{160}2^{-m}\leq\frac{3}{4096% 0},

so 300+1/3+3/40960<301300+1/3+3/40960<301. Taking the monotone limit of the finite frequency cutoffs proves the estimate for the full half-line. ∎

6.4. Endpoint certificates and the interval comparison

The exact reference masses and thresholds are printed in Tables A.1 and A.2. Their directed dual checks prove

(6.12) α⁢(0)≥248035125000,α⁢(log⁡(11/2))≥77597100000.\alpha(0)\geq\frac{248035}{125000},\qquad\alpha(\log(11/2))\geq\frac{77597}{10% 0000}.

These are lower bounds for the full continuum infimum, not empirical minimizers. In each certificate the contour inequality is checked on the whole ellipse; the pinned positive-part integral is checked on its full support; the frequency positive-part integral is checked through 81/1081/10. The endpoint inequalities at 81/1081/10 are part of the directed integrals recomputed from the printed measures: they give Wμ⁢(81/10)>31/10W_{\mu}(81/10)>31/10 for q=2q=2 and Wμ⁢(81/10)>56/5W_{\mu}(81/10)>56/5 for q=11q=11, while the respective thresholds are 1427/5001427/500 and 1217/2001217/200.

The infinite tail has a direct bound that uses only the masses and supports of these two references. Both η0\eta_{0} have mass one and support in E∪ΓE\cup\Gamma, whose real part is at least −751/5000-751/5000; both μ0\mu_{0} have mass one and support in [1/2,9/2][1/2,9/2]. Also B0′B_{0}^{\prime} is the Cauchy transform of a positive measure of mass three on [0,2][0,2]. Differentiating the definition of WμW_{\mu} therefore gives, for t≥81/10t\geq 81/10,

Wμ′⁢(t)\displaystyle W_{\mu}^{\prime}(t) =B0′⁢(t)+log⁡q−log⁡tt−1/2−2⁢∫d⁢μ0⁢(s)t−s−∫ℜ⁡d⁢η0⁢(z)t+z\displaystyle=B_{0}^{\prime}(t)+\log q-\log\frac{t}{t-1/2}-2\int\frac{d\mu_{0}% (s)}{t-s}-\int\Re\frac{d\eta_{0}(z)}{t+z}
≥H⁢(t):=3t+2+log⁡q−log⁡tt−1/2−2t−9/2−1t−751/5000.\displaystyle\geq H(t):=\frac{3}{t+2}+\log q-\log\frac{t}{t-1/2}-\frac{2}{t-9/% 2}-\frac{1}{t-751/5000}.

For t≥81/10t\geq 81/10, differentiation yields

H′⁢(t)=−3(t+2)2+12⁢t⁢(t−1/2)+2(t−9/2)2+1(t−751/5000)2>0,H^{\prime}(t)=-\frac{3}{(t+2)^{2}}+\frac{1}{2t(t-1/2)}+\frac{2}{(t-9/2)^{2}}+% \frac{1}{(t-751/5000)^{2}}>0,

because the last two positive terms exceed 3/t23/t^{2}, while 3/(t+2)2<3/t23/(t+2)^{2}<3/t^{2}. Thus H⁢(t)≥H⁢(81/10)H(t)\geq H(81/10). The elementary bounds log⁡q≥log⁡2>2/3\log q\geq\log 2>2/3, log⁡(81/76)<1/13\log(81/76)<1/13, and 5000/39749<13/1005000/39749<13/100 give

Wμ′⁢(t)≥H⁢(81/10)>30101+69100−113−59−13100=66338295425>31684.W_{\mu}^{\prime}(t)\geq H(81/10)>\frac{30}{101}+\frac{69}{100}-\frac{1}{13}-% \frac{5}{9}-\frac{13}{100}=\frac{66338}{295425}>\frac{31}{684}.

Here we used the elementary rational-series bounds log⁡2>69/100\log 2>69/100, log⁡11>23/10\log 11>23/10, log⁡(81/76)<1/13\log(81/76)<1/13, and 5000/39749<13/1005000/39749<13/100; the q=11q=11 lower bound is larger than 11. Consequently Wμ′⁢(t)>31/684>1/50W_{\mu}^{\prime}(t)>31/684>1/50 for q=2q=2 and is >1>1 for q=11q=11. Hence Wμ⁢(t)>hμW_{\mu}(t)>h_{\mu} on the entire omitted ray, so TT has no omitted tail. The directed endpoint records are summarized in Table 6.1; the exact mass lists are the two preceding reference tables.

For auditability, the scalar inputs and the outward rational penalties used by the two records are listed here (the displayed finite decimals are outward lower bounds for QlogQ_{\log}):

The arithmetic rate used for the positive bases is

τ+⁢(λ)=K+116⁢log⁡(q−1)−1316⁢log⁡q,q=2⁢eλ,\tau_{+}(\lambda)=K+\frac{1}{16}\log(q-1)-\frac{13}{16}\log q,\qquad q=2e^{% \lambda},

where the arithmetic estimate gives K≤1271001/500000K\leq 1271001/500000. Differentiation with respect to λ\lambda gives

τ+′′⁢(λ)=−q16⁢(q−1)2<0.\tau_{+}^{\prime\prime}(\lambda)=-\frac{q}{16(q-1)^{2}}<0.

Its tangent at q0=63/25q_{0}=63/25 has exact slope

τ+′⁢(log⁡(q0/2))=−431608.\tau_{+}^{\prime}(\log(q_{0}/2))=-\frac{431}{608}.

Concavity places τ+\tau_{+} below this tangent on the whole interval. Directed logarithm evaluation with the stated rational upper bound for KK gives the endpoint comparison:

The displayed decimal upper bounds are outward roundings of the directed intervals; the corresponding directed gaps are respectively 0.00323811988930149⁢…0.00323811988930149\ldots and 0.00339263922279043⁢…0.00339263922279043\ldots.

Let L⁢(λ)L(\lambda) be the chord joining the two lower bounds in (6.12). By concavity of α\alpha, α⁢(λ)≥L⁢(λ)\alpha(\lambda)\geq L(\lambda). Let T⁢(λ)T(\lambda) be the tangent to τ+\tau_{+} at q0=63/25q_{0}=63/25. The two directed endpoint checks show L−T>3/1000L-T>3/1000 at both ends. Since L−TL-T is affine in λ\lambda, it is greater than 3/10003/1000 throughout 0≤λ≤log⁡(11/2)0\leq\lambda\leq\log(11/2). Also τ+⁢(λ)≤T⁢(λ)\tau_{+}(\lambda)\leq T(\lambda). We have proved

(6.13) α⁢(λ)−τ+⁢(λ)>31000(0≤λ≤log⁡(11/2)).\alpha(\lambda)-\tau_{+}(\lambda)>\frac{3}{1000}\quad(0\leq\lambda\leq\log(11/% 2)).

The determinant estimate (6.11) is a separate smoothing estimate; the fixed-base integerizer and nonvanishing sequence are applied separately at each integer qq. Thus this section uses no interpolation of integerizers, seed primes, or endpoint reference measures.

7. Positive bases from 2 to 11

The fixed feasible set and affine fields give concavity in λ=log⁡(a/2)\lambda=\log(a/2), as proved in Section 6. The endpoint certificates use exact rational measures on

(ξ,A,B)=(1128110000,1278310000,229200),(\xi,A,B)=\left(\frac{11281}{10000},\frac{12783}{10000},\frac{229}{200}\right),

with 64 contour nodes and Fejér degree 48. They give

α2≥248035125000,α11≥77597100000.\alpha_{2}\geq\frac{248035}{125000},\qquad\alpha_{11}\geq\frac{77597}{100000}.

The arithmetic comparison uses K<1271001/500000K<1271001/500000, tangent point q0=63/25q_{0}=63/25, and slope −431/608-431/608. The directed endpoint gaps exceed 0.00323811988930.0032381198893 and 0.00339263922270.0033926392227, respectively. These checks and the tangent majorant cover 2≤a≤112\leq a\leq 11. The integerization and nonvanishing sequence are applied separately at each integer base. The endpoint measures are printed in Appendix A.

8. Negative bases −7≤a≤−2-7\leq a\leq-2

The signed determinant construction uses the [C;B−T⁢A;V][C;B-TA;V] determinant. At a=−2a=-2, its directed analytic bound is α2>4.34875\alpha_{2}>4.34875, while the fixed arithmetic rate is τ2=A40−(53/48)⁢log⁡2=4.317643952609845⁢…\tau_{2}=A_{40}-(53/48)\log 2=4.317643952609845\ldots, giving margin >0.03110>0.03110. The denominator estimate, prime sum, analytic bound and prime-power nonvanishing sequence includes q=2q=2 and is instantiated at each remaining base. For a=−qa=-q, the field acquires the term −π⁢Im⁡z-\pi\operatorname{Im}z, so the full signed contour in Section 10 is required. For each q=2,…,7q=2,\ldots,7, the contour geometry, printed reference data, and directed field bounds, together with the smoothing estimate in Section 10, give a strict αq>τq\alpha_{q}>\tau_{q}, while Sections 9 and 11 supply the matching integerizer and eventual nonvanishing sequence. Thus all six bases −7≤a≤−2-7\leq a\leq-2 are closed individually, without an interpolation claim across qq.

9. Arithmetic for the signed determinant

This section supplies the arithmetic interface for the negative VV-family. The base is fixed before mm tends to infinity. Thus the statement is made separately for q=2,3,4,5,6,7q=2,3,4,5,6,7, with a=−qa=-q; it is not a theorem uniform in an unbounded parameter qq. The proof has four parts: an exact polynomial divisor, residue-block valuations away from the fixed primes, an outer pole assignment, and a weighted prime-number-theorem sum. All subsequent limits follow from the displayed residue valuations and outer assignment bounds.

Put m=4⁢nm=4n, s=k=h=ns=k=h=n, and

I=[2⁢n,6⁢n),J=[n,10⁢n),Λ={1,…,n},N=10⁢n−1,U=11⁢n−1.I=[2n,6n),\qquad J=[n,10n),\qquad\Lambda=\{1,\ldots,n\},\qquad N=10n-1,\quad U% =11n-1.

For an integer parameter aa, define

tj=∑r=1jaj−rr,bj=∑r=1jaj−rr2,t0=b0=0,t_{j}=\sum_{r=1}^{j}\frac{a^{j-r}}{r},\qquad b_{j}=\sum_{r=1}^{j}\frac{a^{j-r}% }{r^{2}},\qquad t_{0}=b_{0}=0,

and, for i∈Ii\in I, j∈Jj\in J, ℓ∈Λ\ell\in\Lambda,

Ci⁢j={(ai−aj)/(j−i),i≠j,0,i=j,Bi⁢j={(ti−tj)/(j−i),i≠j,bi,i=j,C_{ij}=\begin{cases}(a^{i}-a^{j})/(j-i),&i\neq j,\\ 0,&i=j,\end{cases}\quad B_{ij}=\begin{cases}(t_{i}-t_{j})/(j-i),&i\neq j,\\ b_{i},&i=j,\end{cases}
Ai⁢j=ai⁢δi⁢j,Vℓ⁢j=1j+ℓ,Gm⁢(T;a)=det[C⁢(a)B⁢(a)−T⁢A⁢(a)V].A_{ij}=a^{i}\delta_{ij},\qquad V_{\ell j}=\frac{1}{j+\ell},\qquad G_{m}(T;a)=% \det\begin{bmatrix}C(a)\\ B(a)-TA(a)\\ V\end{bmatrix}.

The determinant has size 2⁢m+n2m+n. All valuations below are coefficientwise in TT: vp⁢(F)=minr⁡vp⁢([Tr]⁢F)v_{p}(F)=\min_{r}v_{p}([T^{r}]F).

9.1. Denominator and the formal divisor

Let dr=lcm⁡(1,…,r)d_{r}=\operatorname{lcm}(1,\ldots,r) and

Δm=dN3⁢m⁢dUn,Dm=⌈53⁢m248⌉−m=⌈53⁢n23⌉−4⁢n.\Delta_{m}=d_{N}^{3m}d_{U}^{n},\qquad D_{m}=\left\lceil\frac{53m^{2}}{48}% \right\rceil-m=\left\lceil\frac{53n^{2}}{3}\right\rceil-4n.
Lemma 9.1 (denominator).

For an indeterminate aa,

Δm⁢Gm⁢(T;a)∈ℤ⁢[a,T].\Delta_{m}G_{m}(T;a)\in\mathbb{Z}[a,T].
Proof.

Every denominator in a CC-entry divides dNd_{N}. In an off-diagonal BB-entry one harmonic denominator and one divided-difference denominator occur, while bib_{i} has two harmonic denominators; hence dN2d_{N}^{2} clears each lower row. The denominators of the VV-rows divide dUd_{U}. Multiplying the rows and expanding the determinant proves the assertion. ∎

Lemma 9.2 (formal aa-divisor).

Coefficientwise in TT,

Δm⁢Gm⁢(T;a)∈aDm⁢(a−1)m⁢ℤ⁢[a,T].\Delta_{m}G_{m}(T;a)\in a^{D_{m}}(a-1)^{m}\mathbb{Z}[a,T].
Proof.

The following argument is coefficientwise in ℚ⁢[[a]]⁢[T]\mathbb{Q}[[a]][T], so every use of an infinite series can be replaced by a finite truncation for a fixed coefficient. For ut⁢(r)=(r−t)−1u_{t}(r)=(r-t)^{-1} when r≠tr\neq t, and ut⁢(t)=0u_{t}(t)=0, put S1⁢(a)=∑v≥1av/vS_{1}(a)=\sum_{v\geq 1}a^{v}/v and S2⁢(a)=∑v≥1av/v2S_{2}(a)=\sum_{v\geq 1}a^{v}/v^{2}. Direct coefficient comparison, including the diagonal entries, gives

Ci⁢j=ai⁢ui⁢(j)+aj⁢uj⁢(i),C_{ij}=a^{i}u_{i}(j)+a^{j}u_{j}(i),
(B−S1⁢C)i⁢j=∑t≥0at⁢ut⁢(i)⁢ut⁢(j)−ai+aj(i−j)2(i≠j),(B-S_{1}C)_{ij}=\sum_{t\geq 0}a^{t}u_{t}(i)u_{t}(j)-\frac{a^{i}+a^{j}}{(i-j)^{% 2}}\quad(i\neq j),

and

(B−T⁢A)i⁢i=∑t≥0at⁢ut⁢(i)2−ai⁢(T+S2⁢(a)).(B-TA)_{ii}=\sum_{t\geq 0}a^{t}u_{t}(i)^{2}-a^{i}(T+S_{2}(a)).

The last formula is the diagonal term and is the reason no off-diagonal limiting convention is needed.

Expand first along the nn rows of VV. In each remaining 2⁢m2m-row minor, use the preceding rank-one expansion. A nonzero term selects 2⁢m=8⁢n2m=8n distinct features. If b,x,y,zb,x,y,z count, respectively, the series features, the upper boundary features, the lower boundary features, and the column boundary features, then b+x+y+z=8⁢nb+x+y+z=8n. Distinctness gives the lower bound

Ψ≥(b2)+(x2)+x⁢max⁡(2⁢n,b)+2⁢n⁢y+(y2)+n⁢z+(z2).\Psi\geq{b\choose 2}+{x\choose 2}+x\max(2n,b)+2ny+{y\choose 2}+nz+{z\choose 2}.

Here the bb series indices are distinct; an upper boundary index cannot be one of them because the two corresponding right vectors coincide. The xx and yy indices are distinct members of I=[2⁢n,6⁢n)I=[2n,6n), while the zz column indices are distinct members of J=[n,10⁢n)J=[n,10n). These are the only features used in the count, so a collision can only delete a term and cannot lower the displayed lower bound. Writing B0=b+xB_{0}=b+x, the right side is at least

Q⁢(B0,y)=B02+B0⁢y+y2−9⁢n⁢B0−7⁢n⁢y+40⁢n2−4⁢n=53⁢n23−4⁢n+r2+r⁢s+s2Q(B_{0},y)=B_{0}^{2}+B_{0}y+y^{2}-9nB_{0}-7ny+40n^{2}-4n=\frac{53n^{2}}{3}-4n+% r^{2}+rs+s^{2}

for suitable real r,sr,s. Since the order is integral, every coefficient of every 2⁢m2m-minor has order at least DmD_{m}. The VV-minors are rational constants independent of a,Ta,T, so expansion along VV gives aDm∣Gm⁢(T;a)a^{D_{m}}\mid G_{m}(T;a) in ℚ⁢[a,T]\mathbb{Q}[a,T]. Combining this with the denominator lemma and monic division gives aDm∣Δm⁢Gma^{D_{m}}\mid\Delta_{m}G_{m} in ℤ⁢[a,T]\mathbb{Z}[a,T].

Finally every CC-entry is divisible by a−1a-1 in ℚ⁢[a]\mathbb{Q}[a], including the zero diagonal convention. There are mm such rows, hence (a−1)m∣Gm(a-1)^{m}\mid G_{m}. The two monic factors aDma^{D_{m}} and (a−1)m(a-1)^{m} are coprime, so their product divides the integral polynomial Δm⁢Gm\Delta_{m}G_{m}. This proves the lemma for every n≥1n\geq 1, not only for the finite verification values. ∎

For a=−qa=-q, the formal divisor implies the exact coefficientwise bound

vp⁢([Tr]⁢Gm⁢(T;−q))≥vp⁢(q)⁢Dm+vp⁢(q+1)⁢m−3⁢m⁢⌊logp⁡N⌋−n⁢⌊logp⁡U⌋.v_{p}([T^{r}]G_{m}(T;-q))\geq v_{p}(q)D_{m}+v_{p}(q+1)m-3m\lfloor\log_{p}N% \rfloor-n\lfloor\log_{p}U\rfloor.

The two credited prime sets are disjoint because gcd⁡(q,q+1)=1\gcd(q,q+1)=1. Notice that this argument includes composite qq and powers pep^{e}; no square-free assumption is being made. For reference, the finite exceptional sets in the five middle cases are

q𝒫q={p:p∣q⁢(q+1)}q𝒫q3{2,3}4{2,5}5{2,3,5}6{2,3,7}7{2,7}\begin{array}[]{c|c@{\qquad}c|c}q&\mathcal{P}_{q}=\{p:p\mid q(q+1)\}&q&% \mathcal{P}_{q}\\ \hline\cr 3&\{2,3\}&4&\{2,5\}\\ 5&\{2,3,5\}&6&\{2,3,7\}\\ 7&\{2,7\}&&\end{array}

The q=2q=2 row is {2,3}\{2,3\}, and is treated by the same rule.

9.2. The pp-unit residue blocks

Fix an odd prime p∤q⁢(q+1)p\nmid q(q+1) with p2>max⁡(N,U)p^{2}>\max(N,U), and write i=u+k⁢pi=u+kp, j=u+ℓ⁢pj=u+\ell p, 0≤u<p0\leq u<p. Since a=−qa=-q and ap≡a(modp)a^{p}\equiv a\pmod{p}, splitting the defining sums at multiples of pp gives

p⁢tu+k⁢p\displaystyle pt_{u+kp} =∑1≤r≤u+k⁢pp∤rp⁢au+k⁢p−rr+∑s=1kau+p⁢(k−s)s≡au⁢tk(modp),\displaystyle=\sum_{\begin{subarray}{c}1\leq r\leq u+kp\\ p\nmid r\end{subarray}}\frac{pa^{u+kp-r}}{r}+\sum_{s=1}^{k}\frac{a^{u+p(k-s)}}% {s}\equiv a^{u}t_{k}\pmod{p},
p2⁢bu+k⁢p\displaystyle p^{2}b_{u+kp} =∑1≤r≤u+k⁢pp∤rp2⁢au+k⁢p−rr2+∑s=1kau+p⁢(k−s)s2≡au⁢bk(modp),p2⁢T⁢Ai⁢j≡0(modp).\displaystyle=\sum_{\begin{subarray}{c}1\leq r\leq u+kp\\ p\nmid r\end{subarray}}\frac{p^{2}a^{u+kp-r}}{r^{2}}+\sum_{s=1}^{k}\frac{a^{u+% p(k-s)}}{s^{2}}\equiv a^{u}b_{k}\pmod{p},\qquad p^{2}TA_{ij}\equiv 0\pmod{p}.

Here k,ℓ<pk,\ell<p follows from i≤Ni\leq N, j≤Uj\leq U, and p2>max⁡(N,U)p^{2}>\max(N,U), so each displayed denominator ss is a pp-unit. Thus the scaled entries satisfy

p⁢Cu+k⁢p,u+ℓ⁢p≡au⁢Ck⁢ℓ(modp),p2⁢Bu+k⁢p,u+ℓ⁢p≡au⁢Bk⁢ℓ(modp),pC_{u+kp,u+\ell p}\equiv a^{u}C_{k\ell}\pmod{p},\qquad p^{2}B_{u+kp,u+\ell p}% \equiv a^{u}B_{k\ell}\pmod{p},

whereas

p⁢Vr,u+ℓ⁢p≡0unless ⁢r+u=p⁢w,p⁢Vr,u+ℓ⁢p=1ℓ+w(r+u=p⁢w).pV_{r,u+\ell p}\equiv 0\quad\text{unless }r+u=pw,\qquad pV_{r,u+\ell p}=\frac{% 1}{\ell+w}\quad(r+u=pw).

The denominators in the last expression are units because p2>Up^{2}>U. Cross-residue CC and BB entries vanish after the displayed row scalings. The reduced residue-uu block has 2⁢|Ku|+|Wu|2|K_{u}|+|W_{u}| rows and |Lu||L_{u}| columns. Therefore its rank over 𝔽p\mathbb{F}_{p} is at most

min⁡(2⁢|Ku|+|Wu|,|Lu|)\min(2|K_{u}|+|W_{u}|,|L_{u}|)

where

Ku={k:1/2≤u/m+k⁢p/m<3/2},Lu={ℓ:1/4≤u/m+ℓ⁢p/m<5/2},K_{u}=\{k:1/2\leq u/m+kp/m<3/2\},\quad L_{u}=\{\ell:1/4\leq u/m+\ell p/m<5/2\},
Wu={w≥1:0<w⁢p/m−u/m≤1/4}.W_{u}=\{w\geq 1:0<wp/m-u/m\leq 1/4\}.

Let rku\operatorname{rk}_{u} denote the actual rank of this reduced block. After permuting rows and columns by residue class, the globally scaled square matrix of order 2⁢m+n2m+n is block diagonal with precisely these blocks. Hence its rank modulo pp equals ∑urku\sum_{u}\operatorname{rk}_{u}, and its determinant has valuation at least

(2⁢m+n)−∑urku.(2m+n)-\sum_{u}\operatorname{rk}_{u}.

The total row-scaling factor is p3⁢m+np^{3m+n}: the CC, BB, and VV rows were scaled by pp, p2p^{2}, and pp, respectively. Undoing this factor gives

vp⁢(Gm⁢(T;−q))≥−(m+∑urku).v_{p}(G_{m}(T;-q))\geq-\left(m+\sum_{u}\operatorname{rk}_{u}\right).

These valuations are coefficientwise in TT. Indeed, the Gauss valuation on ℚp⁢(T)\mathbb{Q}_{p}(T) is discrete with residue field 𝔽p⁢(T)\mathbb{F}_{p}(T); Smith normal form over its valuation ring gives vp⁢(detM)≥(2⁢m+n)−rank⁡(Mmodp)v_{p}(\det M)\geq(2m+n)-\operatorname{rank}(M\bmod p) for every integral square matrix MM of order 2⁢m+n2m+n. Thus only the actual block ranks rku\operatorname{rk}_{u} are credited, not a count of non-divisible rows. Summing the block ranks gives the exponent used below. The only rank saving deliberately credited in the valuation sum is the profile K={0},L={0,1},W=∅K=\{0\},L=\{0,1\},W=\varnothing. After dividing its rows by the unit aua^{u}, its quotient matrix is

(01−a0−1),\begin{pmatrix}0&1-a\\ 0&-1\end{pmatrix},

which has rank one over every residue field. This is a universal identity; no accidental rank deficiency of another profile is credited.

For ρ=p/m\rho=p/m, define

K⁢(x,ρ)={k≥0:1/2≤x+k⁢ρ<3/2},L⁢(x,ρ)={ℓ≥0:1/4≤x+ℓ⁢ρ<5/2},K(x,\rho)=\{k\geq 0:1/2\leq x+k\rho<3/2\},\quad L(x,\rho)=\{\ell\geq 0:1/4\leq x% +\ell\rho<5/2\},
W⁢(x,ρ)={w≥1:0<w⁢ρ−x≤1/4},0≤x<ρ,W(x,\rho)=\{w\geq 1:0<w\rho-x\leq 1/4\},\qquad 0\leq x<\rho,

and define

𝔯⁢(x,ρ)\displaystyle\mathfrak{r}(x,\rho) =min⁡(2⁢|K⁢(x,ρ)|+|W⁢(x,ρ)|,|L⁢(x,ρ)|)\displaystyle=\min(2|K(x,\rho)|+|W(x,\rho)|,|L(x,\rho)|)
−𝟏{K⁢(x,ρ)={0},L⁢(x,ρ)={0,1},W⁢(x,ρ)=∅},\displaystyle\quad-\mathbf{1}_{\{K(x,\rho)=\{0\},\,L(x,\rho)=\{0,1\},\,W(x,% \rho)=\varnothing\}},
𝔠⁢(ρ)\displaystyle\mathfrak{c}(\rho) =1+∫0ρ𝔯⁢(x,ρ)⁢𝑑x.\displaystyle=1+\int_{0}^{\rho}\mathfrak{r}(x,\rho)\,dx.

with the rank-one profile subtracted on its exact active cells. The endpoint conventions are left-closed/right-open for K,LK,L, and w⁢ρ−1/4≤x<w⁢ρw\rho-1/4\leq x<w\rho for WW. Every wall has the form x=c+b⁢ρx=c+b\rho with 4⁢c,b∈ℤ4c,b\in\mathbb{Z}. Since m=4⁢nm=4n, the function is constant on each lattice interval [u/m,(u+1)/m)[u/m,(u+1)/m), and hence

∑u=0p−1𝔯⁢(u/m,p/m)=m⁢∫0p/m𝔯⁢(x,p/m)⁢𝑑x.\sum_{u=0}^{p-1}\mathfrak{r}(u/m,p/m)=m\int_{0}^{p/m}\mathfrak{r}(x,p/m)\,dx.

The residue-block lemma is therefore

vp⁢(Gm⁢(T;−q))≥−m⁢𝔠⁢(p/m).v_{p}(G_{m}(T;-q))\geq-m\mathfrak{c}(p/m).

The proof uses only the p-unit conditions and the index geometry, so it is independent of the value of the fixed qq.

For the arrangement with cutoff R=40R=40, all active walls on 1/40<ρ<5/41/40<\rho<5/4 are enumerated by the finite affine rule above. Define the finite critical set explicitly by

𝒲40={1/40,5/4}∪{c−c′b′−b:x=c+b⁢ρ,x=c′+b′⁢ρ⁢ are listed walls, ⁢140<c−c′b′−b<54}.\mathcal{W}_{40}=\{1/40,5/4\}\cup\left\{\frac{c-c^{\prime}}{b^{\prime}-b}:\ x=% c+b\rho,\ x=c^{\prime}+b^{\prime}\rho\text{ are listed walls, }\frac{1}{40}<% \frac{c-c^{\prime}}{b^{\prime}-b}<\frac{5}{4}\right\}.

At each open interval of this set, choose the least rational midpoint and generate the xx-cells and profiles by the endpoint inequalities above; the profile is constant on the resulting cells. Their exact ordering gives 412 ρ\rho-slabs, 2472 xx-cells and 582 profiles; the one intentionally deficient profile integrates to the saving 5/485/48. More explicitly, retain on 1/40≤ρ≤5/41/40\leq\rho\leq 5/4 and 0≤x≤ρ0\leq x\leq\rho the affine walls

x=0,x=ρ,x=12−k⁢ρ,x=32−k⁢ρ,x=14−ℓ⁢ρ,x=52−ℓ⁢ρ,x=w⁢ρ−14,x=w⁢ρ.\begin{gathered}x=0,\quad x=\rho,\quad x=\tfrac{1}{2}-k\rho,\quad x=\tfrac{3}{% 2}-k\rho,\\ x=\tfrac{1}{4}-\ell\rho,\quad x=\tfrac{5}{2}-\ell\rho,\quad x=w\rho-\tfrac{1}{% 4},\quad x=w\rho.\end{gathered}

for all nonnegative k,ℓk,\ell and positive ww whose line meets the closed strip. Only finitely many such lines occur; sort their pairwise rational intersections and evaluate the exact midpoint profile on each cell. This finite rule gives the 412 ρ\rho-slabs, 2472 xx-cells and 582 profiles without floating-point geometry. The corresponding exact finite comparisons use only the displayed residue blocks and the stated rank formula.

9.3. Outer poles and precedence

For p>5⁢np>5n, use row potentials λB⁢(i),λV⁢(ℓ)\lambda_{B}(i),\lambda_{V}(\ell) and column potentials χ⁢(j)\chi(j) as follows:

range(λB,λV,χ)costpole5⁢n<p<6⁢n(1+[i≥p],1,[j≥p+2⁢n])19⁢n−2⁢pC,B,V6⁢n≤p<8⁢n([i+p<10⁢n],1,[j≥p])19⁢n−2⁢pC,B,V8⁢n≤p<10⁢n(0,1,[j≥p])11⁢n−pC,B,V10⁢n≤p≤U(0,[p−ℓ∈J],0)11⁢n−pV\begin{array}[]{c|c|c|c}\text{range}&(\lambda_{B},\lambda_{V},\chi)&\text{cost% }&\text{pole}\\ \hline\cr 5n<p<6n&(1+[i\geq p],1,[j\geq p+2n])&19n-2p&C,B,V\\ 6n\leq p<8n&([i+p<10n],1,[j\geq p])&19n-2p&C,B,V\\ 8n\leq p<10n&(0,1,[j\geq p])&11n-p&C,B,V\\ 10n\leq p\leq U&(0,[p-\ell\in J],0)&11n-p&V\end{array}

Here brackets are indicator functions. A CC-entry has at most a simple pole at j=i+pj=i+p; a BB-entry has the simple harmonic pole and, when the residue agrees, the second pole (including the diagonal double pole); and a VV-entry has a simple pole at j+ℓ=pj+\ell=p or 2⁢p2p. The potentials in the table dominate these orders entry by entry. In particular, the two families of VV-poles are explicitly included, and no pole is assigned to two ranges. This proves

vp⁢(Gm⁢(T;−q))≥−Epout,Epout={19⁢n−2⁢p,5⁢n<p<8⁢n,11⁢n−p,8⁢n≤p≤U.v_{p}(G_{m}(T;-q))\geq-E_{p}^{\rm out},\qquad E_{p}^{\rm out}=\begin{cases}19n% -2p,&5n<p<8n,\\ 11n-p,&8n\leq p\leq U.\end{cases}

The CC-row potential in the last row is 0; its absence there records that no CC-pole occurs once p>10⁢np>10n. The argument uses only p-unit cancellation and pole locations; it is unchanged when −2-2 is replaced by any fixed −q-q in the p-unit branch.

For completeness, fix the finite set 𝒫q={p:p∣q⁢(q+1)}\mathcal{P}_{q}=\{p:p\mid q(q+1)\}. Let 𝒲40\mathcal{W}_{40} be the exact set of affine ρ\rho-walls in this arrangement, with 1/401/40 and 5/45/4 included as closed endpoints. Define the baseline exponent

enat⁢(p)=3⁢m⁢⌊logp⁡N⌋+n⁢⌊logp⁡U⌋,e_{\rm nat}(p)=3m\left\lfloor\log_{p}N\right\rfloor+n\left\lfloor\log_{p}U% \right\rfloor,

which is the coefficientwise exponent supplied by Δm=dN3⁢m⁢dUn\Delta_{m}=d_{N}^{3m}d_{U}^{n}, and assign the exponent to each prime by the following ordered rule:

Ep,q={enat⁢(p)−vp⁢(q)⁢Dm−vp⁢(q+1)⁢m,p∈𝒫q,enat⁢(p),p∉𝒫q,p≤m/40,enat⁢(p),p∉𝒫q,p2≤max⁡(N,U),enat⁢(p),p∉𝒫q,p/m∈𝒲40,m+∑u𝔯⁢(u/m,p/m),p∉𝒫q, 1/40<p/m<5/4,p/m∉𝒲40,Epout,5⁢n<p≤U,p∉𝒫q,0,p>U.E_{p,q}=\begin{cases}e_{\rm nat}(p)-v_{p}(q)D_{m}-v_{p}(q+1)m,&p\in\mathcal{P}% _{q},\\[2.0pt] e_{\rm nat}(p),&p\notin\mathcal{P}_{q},\ p\leq m/40,\\ e_{\rm nat}(p),&p\notin\mathcal{P}_{q},\ p^{2}\leq\max(N,U),\\ e_{\rm nat}(p),&p\notin\mathcal{P}_{q},\ p/m\in\mathcal{W}_{40},\\[2.0pt] m+\sum_{u}\mathfrak{r}(u/m,p/m),&\begin{subarray}{c}p\notin\mathcal{P}_{q},\ 1% /40<p/m<5/4,\\ p/m\notin\mathcal{W}_{40}\end{subarray},\\[2.0pt] E_{p}^{\rm out},&5n<p\leq U,\ p\notin\mathcal{P}_{q},\\[2.0pt] 0,&p>U.\end{cases}

The first matching line always takes precedence; the cases are therefore an ordered partition even when a small-prime condition overlaps a wall. The outer line begins after the inner range. The coefficientwise bounds above imply

Dm,q∗:=∏ppEp,q,Dm,q∗⁢Gm⁢(T;−q)∈ℤ⁢[T].D^{*}_{m,q}:=\prod_{p}p^{E_{p,q}},\qquad D^{*}_{m,q}G_{m}(T;-q)\in\mathbb{Z}[T].

The exponent in the first line can be negative; this is allowed because the formal divisor supplies the corresponding coefficient valuation. No primitive content or gcd equality is asserted.

9.4. Prime summation and the fixed-base rate

Let ϑ⁢(y)=∑p≤ylog⁡p\vartheta(y)=\sum_{p\leq y}\log p and

εPNT⁢(X)=supy≥X|ϑ⁢(y)y−1|.\varepsilon_{\rm PNT}(X)=\sup_{y\geq X}\left|\frac{\vartheta(y)}{y}-1\right|.

For every affine profile ff on a rational ρ\rho-cell, Stieltjes summation gives

m⁢∑t0⁢m<p<t1⁢mf⁢(p/m)⁢log⁡p=m2⁢∫t0t1f⁢(ρ)⁢𝑑ρ+O⁢(εPNT⁢(m/40)⁢m2+m⁢log⁡(3⁢m)).m\sum_{t_{0}m<p<t_{1}m}f(p/m)\log p=m^{2}\int_{t_{0}}^{t_{1}}f(\rho)\,d\rho+O% \!\left(\varepsilon_{\rm PNT}(m/40)m^{2}+m\log(3m)\right).

The baseline strip contributes 13/16013/160, the deliberately credited profile contributes −5/48-5/48, and the outer potentials contribute 45/3245/32. The exact rational value for this arrangement (including all intervening cells) is

A40\displaystyle A_{40} =N40/D40=5.082993964478118⁢…,\displaystyle=N_{40}/D_{40}=5.082993964478118\ldots,
N40\displaystyle N_{40} =132263363803421925450338622847809742317124551497,\displaystyle=132263363803421925450338622847809742317124551497,
D40\displaystyle D_{40} =26020759561732371877438650035601516684254668800.\displaystyle=26020759561732371877438650035601516684254668800.

Higher prime powers contribute O⁢(m3/2⁢log⁡(3⁢m))O(m^{3/2}\log(3m)). The exact sum over the fixed exceptional set is

∑p∈𝒫qEp,q⁢log⁡p=∑p∈𝒫qenat⁢(p)⁢log⁡p−Dm⁢log⁡q−m⁢log⁡(q+1).\sum_{p\in\mathcal{P}_{q}}E_{p,q}\log p=\sum_{p\in\mathcal{P}_{q}}e_{\rm nat}(% p)\log p-D_{m}\log q-m\log(q+1).

Only the first term on the right is the exceptional-prime cost; since 𝒫q\mathcal{P}_{q} is fixed and N,U=O⁢(m)N,U=O(m), it is Oq⁢(m⁢log⁡(3⁢m))O_{q}(m\log(3m)). The (q+1)m(q+1)^{m} formal factor contributes the separate linear term −m⁢log⁡(q+1)-m\log(q+1). As Dm=53⁢m2/48−m+O⁢(1)D_{m}=53m^{2}/48-m+O(1), the other formal term contributes −5348⁢m2⁢log⁡q+Oq⁢(m)-\frac{53}{48}m^{2}\log q+O_{q}(m). Thus

log⁡Dm,q∗≤(A40−5348⁢log⁡q)⁢m2+rq,m,\log D^{*}_{m,q}\leq\left(A_{40}-\frac{53}{48}\log q\right)m^{2}+r_{q,m},

where

rq,m=O⁢(εPNT⁢(m/40)⁢m2+m3/2⁢log⁡(3⁢m)+m⁢log⁡(3⁢m)+Cqexc⁢m⁢log⁡(3⁢m)+Bq⁢m),r_{q,m}=O\!\left(\varepsilon_{\rm PNT}(m/40)m^{2}+m^{3/2}\log(3m)+m\log(3m)+C_% {q}^{\rm exc}m\log(3m)+B_{q}m\right),

Cqexc=13⁢|𝒫q|/4C_{q}^{\rm exc}=13|\mathcal{P}_{q}|/4, and BqB_{q} is fixed after qq is fixed. Since εPNT⁢(X)→0\varepsilon_{\rm PNT}(X)\to 0, this is oq⁢(m2)o_{q}(m^{2}). The quadratic rates are

qA40−(53/48)⁢log⁡q33.86994289574143.55229394074253.30590626949963.10459288387372.934384841563\begin{array}[]{c|c}q&A_{40}-(53/48)\log q\\ \hline\cr 3&3.869942895741\\ 4&3.552293940742\\ 5&3.305906269499\\ 6&3.104592883873\\ 7&2.934384841563\end{array}

For q=2q=2, the same formal rate is 4.317643952609845⁢…4.317643952609845\ldots; its analytic passage is the q=2q=2 instance of Section 10.

Proposition 9.3 (fixed-base arithmetic transfer).

For each fixed q∈{2,3,4,5,6,7}q\in\{2,3,4,5,6,7\}, the determinant has a rational coefficientwise integerizer satisfying

lim supm→∞, 4∣mm−2⁢log⁡Dm,q∗≤A40−5348⁢log⁡q.\limsup_{m\to\infty,\ 4\mid m}m^{-2}\log D^{*}_{m,q}\leq A_{40}-\frac{53}{48}% \log q.

For q=2,3,4,5,6,7q=2,3,4,5,6,7, the proof is the formal divisor, residue/outer bounds, wall precedence and PNT argument above. The finite comparisons instantiate the displayed formulas; they do not replace the all-mm argument.

10. Signed logarithmic energy and smoothing

For each fixed q∈{2,3,4,5,6,7}q\in\{2,3,4,5,6,7\}, directed interval checks on the printed reference and the smoothing estimate below give an all-mm determinant bound. The interval checks certify the energy rate; the smoothing lemma supplies the estimate for every m=4⁢n≥64m=4n\geq 64.

Throughout, qq is a fixed integer with 2≤q≤72\leq q\leq 7, a=−qa=-q, m=4⁢nm=4n. The three local shape parameters are set to s=k=h=ns=k=h=n, so that L=m+h=5⁢m/4L=m+h=5m/4. The three masses are (Mx,Mv,Mz)=(1,5/4,1)(M_{x},M_{v},M_{z})=(1,5/4,1). Write

I⁢(σ,η)=∬log⁡|u−w|⁢d⁢σ⁢(u)⁢𝑑η⁢(w),Dq⁢(σ,η)=∬log⁡|q+u⁢v|⁢d⁢σ⁢(u)⁢𝑑η⁢(v),I(\sigma,\eta)=\iint\log|u-w|\,d\sigma(u)d\eta(w),\qquad D_{q}(\sigma,\eta)=% \iint\log|q+uv|\,d\sigma(u)d\eta(v),

and

(10.1) 𝒬q⁢(μ)=I⁢(μx,μx)+I⁢(μv,μv)+I⁢(μz,μz)+I⁢(μv,μz)−Dq⁢(μx,μv).\mathcal{Q}_{q}(\mu)=I(\mu_{x},\mu_{x})+I(\mu_{v},\mu_{v})+I(\mu_{z},\mu_{z})+% I(\mu_{v},\mu_{z})-D_{q}(\mu_{x},\mu_{v}).

The supports used for the continuous problem are

𝒦x=𝒦v=[0,1],𝒦z⁢(q)=[−q,−r]∪[r,1]∪{|z|=r},r=3/5.\mathcal{K}_{x}=\mathcal{K}_{v}=[0,1],\qquad\mathcal{K}_{z}(q)=[-q,-r]\cup[r,1% ]\cup\{|z|=r\},\qquad r=3/5.

For a reference triple ν=(νx,νv,νz)\nu=(\nu_{x},\nu_{v},\nu_{z}) of these masses, put

Ui⁢(w)\displaystyle U_{i}(w) =∫log⁡|w−t|⁢d⁢νi⁢(t),\displaystyle=\int\log|w-t|\,d\nu_{i}(t),
Dv⁢(w)\displaystyle D_{v}(w) =∫log⁡|q+w⁢t|⁢d⁢νv⁢(t),\displaystyle=\int\log|q+wt|\,d\nu_{v}(t),
Dx⁢(w)\displaystyle D_{x}(w) =∫log⁡|q+t⁢w|⁢d⁢νx⁢(t).\displaystyle=\int\log|q+tw|\,d\nu_{x}(t).

and define the three fields

F^x⁢(w)\displaystyle\widehat{F}_{x}(w) =2⁢Ux⁢(w)−Dv⁢(w),\displaystyle=2U_{x}(w)-D_{v}(w),
(10.2) F^v⁢(w)\displaystyle\widehat{F}_{v}(w) =2⁢Uv⁢(w)+Uz⁢(w)−Dx⁢(w),\displaystyle=2U_{v}(w)+U_{z}(w)-D_{x}(w),
F^z⁢(w)\displaystyle\widehat{F}_{z}(w) =2⁢Uz⁢(w)+Uv⁢(w),\displaystyle=2U_{z}(w)+U_{v}(w),

For the full logarithmic energy we add the one-body terms separately:

Fx⁢(w)\displaystyle F_{x}(w) =F^x⁢(w)+34⁢log⁡|w|,\displaystyle=\widehat{F}_{x}(w)+\tfrac{3}{4}\log|w|,
(10.3) Fv⁢(w)\displaystyle F_{v}(w) =F^v⁢(w)+14⁢log⁡|w|,\displaystyle=\widehat{F}_{v}(w)+\tfrac{1}{4}\log|w|,
Fz⁢(w)\displaystyle F_{z}(w) =F^z⁢(w)−54⁢log⁡|w|.\displaystyle=\widehat{F}_{z}(w)-\tfrac{5}{4}\log|w|.

The constant field from the determinant prefactor is

(10.4) C0⁢(q)=32⁢log⁡q.C_{0}(q)=\tfrac{3}{2}\log q.

We first identify the determinant at the dilogarithm value. Put

Mi⁢j⁢(q)=∫01∫01xi⁢yjq+x⁢y⁢𝑑x⁢𝑑y,βq=Li2⁡(−1/q),λq=log⁡(1+1/q).M_{ij}(q)=\int_{0}^{1}\!\int_{0}^{1}\frac{x^{i}y^{j}}{q+xy}\,dx\,dy,\qquad% \beta_{q}=\operatorname{Li}_{2}(-1/q),\qquad\lambda_{q}=\log(1+1/q).

For j≥0j\geq 0 set the two moment sequences

mj=∫01ujq+u⁢𝑑u,nj=∫01uj⁢log⁡(1/u)q+u⁢𝑑u.m_{j}=\int_{0}^{1}\frac{u^{j}}{q+u}\,du,\qquad n_{j}=\int_{0}^{1}\frac{u^{j}% \log(1/u)}{q+u}\,du.

Polynomial division gives, for j≥1j\geq 1,

mj=−q⁢mj−1+1j,nj=−q⁢nj−1+1j2,m_{j}=-qm_{j-1}+\frac{1}{j},\qquad n_{j}=-qn_{j-1}+\frac{1}{j^{2}},

while m0=λqm_{0}=\lambda_{q} and n0=−βqn_{0}=-\beta_{q}. Hence, with the polynomials tj,bjt_{j},b_{j} of Section 9,

mj=(−q)j⁢λq+tj,nj=bj−(−q)j⁢βq.m_{j}=(-q)^{j}\lambda_{q}+t_{j},\qquad n_{j}=b_{j}-(-q)^{j}\beta_{q}.

The substitution u=x⁢yu=xy yields

Mi⁢j⁢(q)=mi−mjj−i(i≠j),Mi⁢i⁢(q)=ni,M_{ij}(q)=\frac{m_{i}-m_{j}}{j-i}\quad(i\neq j),\qquad M_{ii}(q)=n_{i},

and therefore

(10.5) M⁢(q)=B⁢(−q)+λq⁢C⁢(−q)−βq⁢A⁢(−q).M(q)=B(-q)+\lambda_{q}C(-q)-\beta_{q}A(-q).

Adding λq\lambda_{q} times each CC row to the corresponding row of B⁢(−q)−βq⁢A⁢(−q)B(-q)-\beta_{q}A(-q) preserves the determinant. Thus the determinant of Section 9, evaluated at T=βqT=\beta_{q}, is exactly the determinant with middle block M⁢(q)M(q).

10.1. The path and the signed energy

Let γ+⁢(t)=r⁢ei⁢t\gamma_{+}(t)=re^{it} for 0≤t≤π0\leq t\leq\pi and γ−⁢(t)=r⁢ei⁢t\gamma_{-}(t)=re^{it} for π≤t≤2⁢π\pi\leq t\leq 2\pi. Orient the two real segments increasingly and set

(10.6) Γq=[−q,−r]+[r,1]+(cq−1)⁢γ++cq⁢γ−,cq=log⁡q+i⁢π2⁢π⁢i.\Gamma_{q}=[-q,-r]+[r,1]+(c_{q}-1)\gamma_{+}+c_{q}\gamma_{-},\qquad c_{q}=% \frac{\log q+i\pi}{2\pi i}.

For every integer dd,

(10.7) ∫Γqzd−1⁢𝑑z={(1−(−q)d)/d,d≠0,0,d=0.\int_{\Gamma_{q}}z^{d-1}\,dz=\begin{cases}(1-(-q)^{d})/d,&d\neq 0,\\ 0,&d=0.\end{cases}

For d≠0d\neq 0, integrate zd−1z^{d-1} on each piece using the primitive zd/dz^{d}/d; the two circular half-arcs contribute exactly the terms needed to cancel the intermediate endpoints ±r\pm r. For d=0d=0, the real pieces give −log⁡q-\log q, while the circular pieces give i⁢π⁢(2⁢cq−1)=log⁡qi\pi(2c_{q}-1)=\log q. This also fixes the branch convention at the zero Laurent moment.

The same Andreief identity [1, 3] and Cauchy–Vandermonde expansions [6] as for the determinant in Section 9, now using (10.7), give

Proof of the integral representation.

By (10.7), Ci⁢j=(−q)i⁢∫Γqzj−i−1⁢𝑑zC_{ij}=(-q)^{i}\int_{\Gamma_{q}}z^{j-i-1}\,dz. Put fi⁢(v)=∫01xi/(q+x⁢v)⁢𝑑xf_{i}(v)=\int_{0}^{1}x^{i}/(q+xv)\,dx. Then the lower rational block and the V block are respectively

Mi⁢j=∫01fi⁢(v)⁢vj⁢𝑑v,Vℓ⁢j=∫01vℓ−1⁢vj⁢𝑑v.M_{ij}=\int_{0}^{1}f_{i}(v)v^{j}\,dv,\qquad V_{\ell j}=\int_{0}^{1}v^{\ell-1}v% ^{j}\,dv.

For integrable families, Andreief’s identity [1, 3] is

det(∫fi⁢(t)⁢gj⁢(t)⁢𝑑t)i,j=1N=1N!⁢∫det(fi⁢(tb))i,b=1N⁢det(gj⁢(tb))b,j=1N⁢∏b=1Nd⁢tb.\det\left(\int f_{i}(t)g_{j}(t)\,dt\right)_{i,j=1}^{N}=\frac{1}{N!}\int\det(f_% {i}(t_{b}))_{i,b=1}^{N}\det(g_{j}(t_{b}))_{b,j=1}^{N}\prod_{b=1}^{N}dt_{b}.

Apply it successively to the LL lower/V rows, the mm contour rows, and the mm functions fif_{i}. These three applications account respectively for 1/L!1/L!, 1/m!1/m!, and 1/m!1/m!:

Gm=1(m!)2⁢L!⁢∫Dz⁢Dz⁢v⁢Dx⁢Dx⁢v⁢𝑑x⁢𝑑v⁢𝑑z.G_{m}=\frac{1}{(m!)^{2}L!}\int D_{z}D_{zv}D_{x}D_{xv}\,dx\,dv\,dz.

Here eΔ=m⁢(m−1)/2e_{\Delta}=m(m-1)/2 and, with 𝐰=(z1,…,zm,v1,…,vL)\mathbf{w}=(z_{1},\ldots,z_{m},v_{1},\ldots,v_{L}), the four determinants are

Dz\displaystyle D_{z} =det((−q)i⁢zd−i−1)i∈I,d=(−1)eΔ⁢(−q)∑i∈Ii⁢Δ⁢(z)⁢∏dzd−3⁢m/2,\displaystyle=\det\bigl{(}(-q)^{i}z_{d}^{-i-1}\bigr{)}_{i\in I,d}=(-1)^{e_{% \Delta}}(-q)^{\sum_{i\in I}i}\Delta(z)\prod_{d}z_{d}^{-3m/2},
Dz⁢v\displaystyle D_{zv} =det(𝐰bj)b,j∈J=(−1)m⁢L⁢Δ⁢(z)⁢Δ⁢(v)⁢∏dzdm/4⁢∏bvbm/4⁢∏d,b(zd−vb),\displaystyle=\det(\mathbf{w}_{b}^{j})_{b,j\in J}=(-1)^{mL}\Delta(z)\Delta(v)% \prod_{d}z_{d}^{m/4}\prod_{b}v_{b}^{m/4}\prod_{d,b}(z_{d}-v_{b}),
Dx\displaystyle D_{x} =det(xi′i)i∈I,i′=Δ⁢(x)⁢∏i′xi′m/2,\displaystyle=\det(x_{i^{\prime}}^{i})_{i\in I,i^{\prime}}=\Delta(x)\prod_{i^{% \prime}}x_{i^{\prime}}^{m/2},
Dx⁢v\displaystyle D_{xv} =det(((q+xi′⁢vb)−1)i′,b(vbℓ−1)ℓ,b)=(−1)eΔ⁢qeΔ⁢Δ⁢(x)⁢Δ⁢(v)⁢∏i′xi′m/4∏i′,b(q+xi′⁢vb).\displaystyle=\det\begin{pmatrix}((q+x_{i^{\prime}}v_{b})^{-1})_{i^{\prime},b}% \\ (v_{b}^{\ell-1})_{\ell,b}\end{pmatrix}=\frac{(-1)^{e_{\Delta}}q^{e_{\Delta}}% \Delta(x)\Delta(v)\prod_{i^{\prime}}x_{i^{\prime}}^{m/4}}{\prod_{i^{\prime},b}% (q+x_{i^{\prime}}v_{b})}.

The last equality is the Cauchy–Vandermonde identity [6]. For completeness, for ti′=q/xi′t_{i^{\prime}}=q/x_{i^{\prime}} it follows from

det(((ti′+vb)−1)i′,b(vbℓ−1)ℓ,b)=Δ⁢(t)⁢Δ⁢(v)∏i′,b(ti′+vb),\det\begin{pmatrix}((t_{i^{\prime}}+v_{b})^{-1})_{i^{\prime},b}\\ (v_{b}^{\ell-1})_{\ell,b}\end{pmatrix}=\frac{\Delta(t)\Delta(v)}{\prod_{i^{% \prime},b}(t_{i^{\prime}}+v_{b})},

after multiplying the first mm rows by xi′−1x_{i^{\prime}}^{-1} and using Δ⁢(t)=(−1)eΔ⁢qeΔ⁢Δ⁢(x)⁢∏i′xi′1−m\Delta(t)=(-1)^{e_{\Delta}}q^{e_{\Delta}}\Delta(x)\prod_{i^{\prime}}x_{i^{% \prime}}^{1-m}. Here is a proof of the identity, for every m,h≥0m,h\geq 0 with L=m+hL=m+h. Treat the tit_{i} and vbv_{b} as independent indeterminates. The case m=0m=0 is the Vandermonde determinant. Assume the formula for m−1m-1 and all h≥0h\geq 0, and regard both sides as rational functions of vLv_{L}. Expanding the determinant along its last column, its residue at vL=−tiv_{L}=-t_{i} is (−1)i+L(-1)^{i+L} times the complementary minor. By induction this residue is

(−1)i+L⁢Δ⁢(t^i)⁢Δ⁢(v1,…,vL−1)∏j≠i∏b<L(tj+vb).(-1)^{i+L}\frac{\Delta(\widehat{t}_{i})\Delta(v_{1},\ldots,v_{L-1})}{\prod_{j% \neq i}\prod_{b<L}(t_{j}+v_{b})}.

The proposed quotient has the same residue: substitute vL=−tiv_{L}=-t_{i}, cancel the factors tj−tit_{j}-t_{i} and ti+vbt_{i}+v_{b}, and use Δ⁢(t)=(−1)i−1⁢Δ⁢(t^i)⁢∏j≠i(tj−ti)\Delta(t)=(-1)^{i-1}\Delta(\widehat{t}_{i})\prod_{j\neq i}(t_{j}-t_{i}). Hence the difference has no finite poles. After cancellation of the denominator ∏i(ti+vL)\prod_{i}(t_{i}+v_{L}), the difference is a polynomial in vLv_{L} of degree at most h−1h-1. It vanishes at each of the L−1L-1 values vL=vbv_{L}=v_{b} (b<Lb<L), since both sides have the factor Δ⁢(v)\Delta(v). For m≥1m\geq 1, L−1=m+h−1≥hL-1=m+h-1\geq h, so these roots force the polynomial to be zero. When h=0h=0, the difference tends to zero at infinity instead. This proves the Cauchy–Vandermonde identity.

Multiplying the four displayed factors gives precisely Φq\Phi_{q}: the m/2m/2 from DxD_{x} and the m/4m/4 from Dx⁢vD_{xv} combine to the displayed 3⁢m/43m/4 power of each xi′x_{i^{\prime}}. The sign is (−1)∑i∈Ii+2⁢eΔ+m⁢L=1(-1)^{\sum_{i\in I}i+2e_{\Delta}+mL}=1: here ∑i∈Ii=2⁢n⁢(8⁢n−1)\sum_{i\in I}i=2n(8n-1) and m⁢L=20⁢n2mL=20n^{2} are even. The q-power is

∑i∈Ii+eΔ=m⁢(2⁢n)+m⁢(m−1)=3⁢m22−m,(m=4⁢n,L=5⁢n).\sum_{i\in I}i+e_{\Delta}=m(2n)+m(m-1)=\frac{3m^{2}}{2}-m,\qquad(m=4n,\ L=5n).

The factors q+xi⁢vbq+x_{i}v_{b} are at least qq, while |z|≥r|z|\geq r on Γq\Gamma_{q}; all three integrations therefore converge absolutely. The m!m!, L!L!, and m!m! factors are exactly the three Andreief symmetrizations, proving (10.8). ∎

For triples of positive measures of the stated masses, define

Lemma 10.1 (signed-energy concavity for fixed qq).

Let μ,ν\mu,\nu be triples of positive measures of masses (1,5/4,1)(1,5/4,1), supported in compact subsets of the indicated supports or their sufficiently small tubular neighborhoods. Assume that the pairings in 𝒬q\mathcal{Q}_{q} are finite real numbers. No absolute logarithmic moment assumption is imposed on a competitor’s xx- or vv-component. Then

𝒬q⁢(μ)≤−𝒬q⁢(ν)+∫F^x⁢𝑑μx+∫F^v⁢𝑑μv+∫F^z⁢𝑑μz,\mathcal{Q}_{q}(\mu)\leq-\mathcal{Q}_{q}(\nu)+\int\widehat{F}_{x}\,d\mu_{x}+% \int\widehat{F}_{v}\,d\mu_{v}+\int\widehat{F}_{z}\,d\mu_{z},

where the hatted fields are formed from ν\nu. Consequently the same inequality for the full energy is obtained by adding the displayed one-body terms to the hatted fields, i.e. by using Fx,Fv,FzF_{x},F_{v},F_{z} in the field bounds.

Proof.

By the shared quadratic-duality identity in Section C, it suffices to prove that the zero-mass quadratic remainder 𝒬q⁢(μ−ν)\mathcal{Q}_{q}(\mu-\nu) is nonpositive. First suppose that all vv-supports avoid zero. For a signed measure σ\sigma of mass zero, write ‖σ‖2=−I⁢(σ,σ)≥0\|\sigma\|^{2}=-I(\sigma,\sigma)\geq 0; this is the zero-mass logarithmic-energy positivity lemma. Put Rq⁢(v)=−q/vR_{q}(v)=-q/v. The exact identities

log⁡|q+x⁢v|\displaystyle\log|q+xv| =log⁡|x−Rq⁢(v)|+log⁡|v|,\displaystyle=\log|x-R_{q}(v)|+\log|v|,
log⁡|Rq⁢(v)−Rq⁢(w)|\displaystyle\log|R_{q}(v)-R_{q}(w)| =log⁡q+log⁡|v−w|−log⁡|v|−log⁡|w|\displaystyle=\log q+\log|v-w|-\log|v|-\log|w|

Integrating against zero-mass measures cancels all one-variable terms and gives

Dq⁢(σx,σv)\displaystyle D_{q}(\sigma_{x},\sigma_{v}) =I⁢(σx,(Rq)∗⁢σv),\displaystyle=I(\sigma_{x},(R_{q})_{*}\sigma_{v}),
I⁢((Rq)∗⁢σv,(Rq)∗⁢σv)\displaystyle I((R_{q})_{*}\sigma_{v},(R_{q})_{*}\sigma_{v}) =I⁢(σv,σv).\displaystyle=I(\sigma_{v},\sigma_{v}).

Let σi=μi−νi\sigma_{i}=\mu_{i}-\nu_{i}, and set σx′=σx\sigma^{\prime}_{x}=\sigma_{x}, σv′=(Rq)∗⁢σv\sigma^{\prime}_{v}=(R_{q})_{*}\sigma_{v}, σz′=−(Rq)∗⁢σz\sigma^{\prime}_{z}=-(R_{q})_{*}\sigma_{z}. Then

𝒬q⁢(σ)=−‖σx′‖2−‖σv′‖2−‖σz′‖2+⟨σx′,σv′⟩+⟨σv′,σz′⟩,⟨α,β⟩=−I⁢(α,β).\mathcal{Q}_{q}(\sigma)=-\|\sigma^{\prime}_{x}\|^{2}-\|\sigma^{\prime}_{v}\|^{% 2}-\|\sigma^{\prime}_{z}\|^{2}+\langle\sigma^{\prime}_{x},\sigma^{\prime}_{v}% \rangle+\langle\sigma^{\prime}_{v},\sigma^{\prime}_{z}\rangle,\qquad\langle% \alpha,\beta\rangle=-I(\alpha,\beta).

The right side equals

−12⁢(‖σx′−σv′‖2+‖σv′−σz′‖2+‖σx′‖2+‖σz′‖2)≤0.-\tfrac{1}{2}\bigl{(}\|\sigma^{\prime}_{x}-\sigma^{\prime}_{v}\|^{2}+\|\sigma^% {\prime}_{v}-\sigma^{\prime}_{z}\|^{2}+\|\sigma^{\prime}_{x}\|^{2}+\|\sigma^{% \prime}_{z}\|^{2}\bigr{)}\leq 0.

The shared identity gives the asserted quadratic inequality. For a competitor μv\mu_{v} whose support meets zero, fix a smooth probability measure ρ\rho supported in [3/4,7/8][3/4,7/8]. For 0<δ<1/40<\delta<1/4, let λδ=μv|{|v|<δ}\lambda_{\delta}=\mu_{v}|_{\{|v|<\delta\}}, let eδ=λδ⁢(ℂ)e_{\delta}=\lambda_{\delta}(\mathbb{C}), and set

μv,δ=μv−λδ+eδ⁢ρ.\mu_{v,\delta}=\mu_{v}-\lambda_{\delta}+e_{\delta}\rho.

Finite logarithmic self-energy excludes an atom at zero, so eδ→0e_{\delta}\to 0 and μv,δ⇒μv\mu_{v,\delta}\Rightarrow\mu_{v}. Absolute integrability of the logarithmic pairings in 𝒬q\mathcal{Q}_{q} implies that the integrals over the deleted sets tend to zero. The replacement terms involving eδ⁢ρe_{\delta}\rho tend to zero as well: ρ\rho is separated from {|v|<δ}\{|v|<\delta\}, and its logarithmic potential is bounded on the compact supports. The kernel log⁡|q+u⁢v|\log|q+uv| is bounded and continuous on the stated tubes because q≥2q\geq 2 and |u|,|v|≤1+o⁢(1)|u|,|v|\leq 1+o(1). Hence 𝒬q⁢(μx,μv,δ,μz)→𝒬q⁢(μ)\mathcal{Q}_{q}(\mu_{x},\mu_{v,\delta},\mu_{z})\to\mathcal{Q}_{q}(\mu). The reference fields F^i\widehat{F}_{i} are continuous and bounded on these compact sets, so their integrals also converge. Applying the already proved inequality to μv,δ\mu_{v,\delta} and taking the limit proves the quadratic inequality without requiring ∫|log⁡|v||⁢𝑑μv<∞\int|\log|v||\,d\mu_{v}<\infty.

The one-body integrals in ℰq\mathcal{E}_{q} are then interpreted as extended real integrals. On the compact xx- and vv-supports, log⁡|w|\log|w| is bounded above and can have integral −∞-\infty; on the zz-support, |z|≥r−o⁢(1)|z|\geq r-o(1), so the zz-term is finite. Adding these linear terms to the quadratic inequality is therefore valid in the extended reals. In particular, when the full energy is −∞-\infty the asserted upper bound is automatic. This argument uses no implication from finite self-energy to a finite absolute logarithmic moment. ∎

Each printed reference has finitely many positive-length rational interval rows, compact zz support in [−q,−3/5][-q,-3/5], and Poisson centres with |c|<3/5|c|<3/5; the xx and vv chains start at the positive endpoints listed in the data section and end at 11. Hence all six reference supports are compact and avoid zero. Interval densities are bounded by the finite maximum of their rational mass/length ratios, while a Poisson row of mass ww has density

w2⁢π⁢r2−|c|2|r⁢ei⁢θ−c|2≤w⁢(r+|c|)2⁢π⁢r⁢(r−|c|),r=3/5.\frac{w}{2\pi}\frac{r^{2}-|c|^{2}}{|re^{i\theta}-c|^{2}}\leq\frac{w(r+|c|)}{2% \pi r(r-|c|)},\qquad r=3/5.

Thus the printed references have finite logarithmic moments directly from their rational supports, without any general self-energy implication.

Combining the lemma with the one-body terms gives the explicit full-energy upper bound used below:

(10.10) ℰq⁢(μ)≤C0⁢(q)−𝒬q⁢(ν)+∫Fx⁢𝑑μx+∫Fv⁢𝑑μv+∫Fz⁢𝑑μz.\mathcal{E}_{q}(\mu)\leq C_{0}(q)-\mathcal{Q}_{q}(\nu)+\int F_{x}\,d\mu_{x}+% \int F_{v}\,d\mu_{v}+\int F_{z}\,d\mu_{z}.

Thus, if the full fields are bounded above by Kx,q,Kv,q,Kz,qK_{x,q},K_{v,q},K_{z,q} on their respective admissible supports, then

(10.11) ℰq⁢(μ)≤−(𝒬q⁢(ν)−C0⁢(q)−Kx,q−54⁢Kv,q−Kz,q).\mathcal{E}_{q}(\mu)\leq-\bigl{(}\mathcal{Q}_{q}(\nu)-C_{0}(q)-K_{x,q}-\tfrac{% 5}{4}K_{v,q}-K_{z,q}\bigr{)}.

The inversion is valid uniformly for the fixed bases considered here: on |v|≤1+3/4096|v|\leq 1+3/4096, |Rq′⁢(v)|=q/|v|2>1|R_{q}^{\prime}(v)|=q/|v|^{2}>1 for q≥2q\geq 2. Thus a bounded arclength density pushes forward to a bounded arclength density on each inverted segment or circle. No q=2q=2 numerical identity is used in the concavity argument.

10.2. Directed fixed-base certificates

For a reference triple νq\nu_{q}, suppose its energy lower endpoint is Qq,−Q_{q,-} and its support-wide field upper bounds are Fx≤Kx,qF_{x}\leq K_{x,q}, Fv≤Kv,qF_{v}\leq K_{v,q}, Fz≤Kz,qF_{z}\leq K_{z,q}. Lemma 10.1 and (10.9) give the quadratic rate

(10.12) αq=Qq,−−32⁢log⁡q−Kx,q−54⁢Kv,q−Kz,q.\alpha_{q}=Q_{q,-}-\tfrac{3}{2}\log q-K_{x,q}-\tfrac{5}{4}K_{v,q}-K_{z,q}.

The following are the directed interval-bound results. The field thresholds are exact terminating decimals. The displayed α\alpha values are strict lower bounds rounded down, and each τ\tau is an outward-rounded upper bound.

The energy lower endpoints used in (10.12) are printed separately so that the energy and field slacks can be checked independently:

For each q=2,…,7q=2,\ldots,7, put δ=1/250\delta=1/250. The boxes 0≤x,v≤δ0\leq x,v\leq\delta are discharged by the endpoint bounds (10.13). On [δ,1][\delta,1] and on the two real zz intervals, including the complete negative interval [−q,−3/5][-q,-3/5], the subdivision recursively bisects each rational midpoint. A cell is accepted exactly when its directed upper field interval is finite and strictly below the displayed threshold; otherwise both children are visited, in left-first order, with maximum depth 3030. Circle cells use the same rule in the parameter t∈[0,1]t\in[0,1], and the endpoints t=0,1t=0,1 are checked directly. This is the complete partition rule. The six references contain 17331733 rows in all, and their rows are printed in Section B. The smoothing lemma below supplies the complex-tube transfer and the all-mm estimate.

10.3. Reference densities and directed endpoint disks

All constants below are computed from the signed decimal tables in Section B. For each interval row [a,b][a,b] of mass ww, put H=w/(b−a)H=w/(b-a). Let Hx,qH_{x,q}, Hv,qH_{v,q} and Hz,qH_{z,q} be the largest such value in the xx, vv and negative-real zz chains. For a Poisson row (c,w)(c,w) write

ρc=2−120⁢⌈2120⁢|c|⌉,Pq=∑(c,w)w⁢(r+ρc)r⁢(r−ρc).\rho_{c}=2^{-120}\left\lceil 2^{120}|c|\right\rceil,\qquad P_{q}=\sum_{(c,w)}% \frac{w(r+\rho_{c})}{r(r-\rho_{c})}.

The ceiling is evaluated by integer square root on the printed rational coordinates, and the construction checks ρc<r\rho_{c}<r row by row. Since the Poisson density on |z|=r|z|=r is at most w⁢(r+ρc)/(2⁢π⁢r⁢(r−ρc))w(r+\rho_{c})/(2\pi r(r-\rho_{c})) per unit arclength, and a circle meets a disk of radius tt in arclength at most 2⁢π⁢t2\pi t, the reference measures satisfy νi⁢(B⁢(w,t))≤Ai,q⁢t\nu_{i}(B(w,t))\leq A_{i,q}t, where

Ax,q=2⁢Hx,q,Av,q=2⁢Hv,q,Az,q=2⁢Hz,q+Pq.A_{x,q}=2H_{x,q},\qquad A_{v,q}=2H_{v,q},\qquad A_{z,q}=2H_{z,q}+P_{q}.

In the table, Σq\Sigma_{q} is rounded upward to 10−310^{-3} and this rounded rational value is used in 𝒞q\mathcal{C}_{q}. The path variation is

The Ex,qE_{x,q} and Ev,qE_{v,q} columns are rounded upward to 10−410^{-4}; the 𝒯q\mathcal{T}_{q} column is rounded upward to 10−610^{-6}.

For δ=1/250\delta=1/250, put P⁢(t)=t⁢(log⁡t−1)P(t)=t(\log t-1) and define the exact real integrals

Jx,q=∫log⁡(t+δ)⁢𝑑νx⁢(t),Jv,q=∫log⁡(t+δ)⁢𝑑νv⁢(t),Jz,q=∫log⁡(|z|+δ)⁢𝑑νz⁢(z).J_{x,q}=\int\log(t+\delta)\,d\nu_{x}(t),\quad J_{v,q}=\int\log(t+\delta)\,d\nu% _{v}(t),\quad J_{z,q}=\int\log(|z|+\delta)\,d\nu_{z}(z).

An interval contributes w⁢(P⁢(b+δ)−P⁢(a+δ))/(b−a)w(P(b+\delta)-P(a+\delta))/(b-a); for a negative zz interval use endpoints −a,−b-a,-b in increasing order. The Poisson rows together contribute their total mass times log⁡(r+δ)\log(r+\delta). For |w0|≤δ|w_{0}|\leq\delta, the triangle inequality and the masses give

Fx⁢(w0)\displaystyle F_{x}(w_{0}) ≤Ex,q:=2⁢Jx,q−54⁢log⁡(q−δ)+34⁢log⁡δ,\displaystyle\leq E_{x,q}:=2J_{x,q}-\frac{5}{4}\log(q-\delta)+\frac{3}{4}\log\delta,
(10.13) Fv⁢(w0)\displaystyle F_{v}(w_{0}) ≤Ev,q:=2⁢Jv,q+Jz,q−log⁡(q−δ)+14⁢log⁡δ.\displaystyle\leq E_{v,q}:=2J_{v,q}+J_{z,q}-\log(q-\delta)+\frac{1}{4}\log\delta.

The endpoint bounds are directed upper endpoints rounded upward at 10−410^{-4}. The same table gives Σq\Sigma_{q} rounded upward at 10−310^{-3} and 𝒯q\mathcal{T}_{q} rounded upward at 10−610^{-6}; throughout the proof set 𝒞q=10+3⁢Σq\mathcal{C}_{q}=10+3\Sigma_{q} using the printed Σq\Sigma_{q}.

The endpoint entries satisfy Ex,q<Kx,qE_{x,q}<K_{x,q} and Ev,q<Kv,qE_{v,q}<K_{v,q}, where the field bounds are in Table 10.1. The displayed Σq\Sigma_{q} values give the explicit coefficients 𝒞q=10+3⁢Σq\mathcal{C}_{q}=10+3\Sigma_{q}; no unprinted density or endpoint constant is used below.

10.4. The all-mm smoothing estimate

Lemma 10.2 (logarithmic-potential modulus).

If a compactly supported positive measure η\eta of mass MM satisfies η⁢(B⁢(w,t))≤A⁢t\eta(B(w,t))\leq At for every disk, then for d=|w−w′|≤1/3d=|w-w^{\prime}|\leq 1/3,

|Uη⁢(w)−Uη⁢(w′)|≤(6⁢A+2⁢M)⁢d⁢(1+log⁡(1/d)).|U_{\eta}(w)-U_{\eta}(w^{\prime})|\leq(6A+2M)d\bigl{(}1+\log(1/d)\bigr{)}.
Proof.

Let N={z:|w−z|≤2⁢d}N=\{z:|w-z|\leq 2d\}. On NN both distances are at most 3⁢d3d. Approximating the closed disk from outside gives η⁢(N)≤2⁢A⁢d\eta(N)\leq 2Ad. For either centre w∗=w,w′w_{*}=w,w^{\prime}, layer cake bounds the integral on NN by

∫Nlog⁡1|w∗−z|⁢d⁢η⁢(z)≤∫0∞min⁡(2⁢A⁢d,A⁢e−s)⁢𝑑s=2⁢A⁢d⁢(1+log⁡(1/(2⁢d))).\int_{N}\log\frac{1}{|w_{*}-z|}\,d\eta(z)\leq\int_{0}^{\infty}\min(2Ad,Ae^{-s}% )\,ds=2Ad\bigl{(}1+\log(1/(2d))\bigr{)}.

Off NN, the logarithmic difference is at most 2⁢d/|w−z|2d/|w-z|, while another layer-cake integration gives ∫|w−z|>2⁢d|w−z|−1⁢𝑑η⁢(z)≤M+A⁢log⁡(1/(2⁢d))\int_{|w-z|>2d}|w-z|^{-1}d\eta(z)\leq M+A\log(1/(2d)). Adding these bounds gives at most 6⁢A⁢d⁢log⁡(1/d)+2⁢M⁢d6Ad\log(1/d)+2Md, which is bounded by the displayed expression. ∎

For q=2,…,7q=2,\ldots,7, let αq\alpha_{q} be the strict lower endpoints in Table 10.1. In particular, the printed table verifies αq>τq\alpha_{q}>\tau_{q} in each of the six cases. Then for every m=4⁢n≥64m=4n\geq 64,

(10.14) log⁡|Gm⁢(Li2⁡(−1/q);−q)|≤−αq⁢m2+𝒞q⁢m⁢log⁡m,𝒞q=10+3⁢Σq.\log|G_{m}(\operatorname{Li}_{2}(-1/q);-q)|\leq-\alpha_{q}m^{2}+\mathcal{C}_{q% }m\log m,\qquad\mathcal{C}_{q}=10+3\Sigma_{q}.
Proof.

Fix qq and a nonzero integrand point in (10.8). Put ϵ=m−2\epsilon=m^{-2}. Replace each atom uu of its empirical measures by the uniform probability measure on u+2⁢i⁢ϵ+ϵ⁢ei⁢ϑu+2i\epsilon+\epsilon e^{i\vartheta}. Every point of this circle is within 3⁢ϵ3\epsilon of uu. The common translation preserves pairwise centres; subharmonicity of log⁡|z|\log|z| shows that every off-diagonal positive logarithmic pair energy does not decrease. Each diagonal circle has self-energy log⁡ϵ\log\epsilon, and there are m+5⁢m/4+m=13⁢m/4m+5m/4+m=13m/4 atoms. Thus, writing μϵ\mu^{\epsilon} for the smoothed empirical triple and 𝒬q,disc\mathcal{Q}_{q,\rm disc} for the three self-energies with their diagonals removed,

𝒬q,disc⁢(μ)≤𝒬q⁢(μϵ)+134⁢m⁢log⁡(1/ϵ)+CD,q⁢ϵ,CD,q=8⁢LD,q,LD,q=1+3/4096q−(1+3/4096)2.\mathcal{Q}_{q,\rm disc}(\mu)\leq\mathcal{Q}_{q}(\mu^{\epsilon})+\frac{13}{4m}% \log(1/\epsilon)+C_{D,q}\epsilon,\quad C_{D,q}=8L_{D,q},\quad L_{D,q}=\frac{1+% 3/4096}{q-(1+3/4096)^{2}}.

Indeed, on the two smearing disks |u|,|v|≤1+3⁢ϵ|u|,|v|\leq 1+3\epsilon and |u⁢v−x⁢v0|≤6⁢ϵ+9⁢ϵ2|uv-xv_{0}|\leq 6\epsilon+9\epsilon^{2}. The denominator stays at distance at least q−(1+3/4096)2q-(1+3/4096)^{2} from zero. The mean-value bound for log⁡|q+u⁢v|\log|q+uv|, multiplied by the cross mass 5/45/4, is at most

(152+454⁢ϵ)⁢LD,q⁢ϵ≤CD,q⁢ϵ,\left(\frac{15}{2}+\frac{45}{4}\epsilon\right)L_{D,q}\epsilon\leq C_{D,q}\epsilon,

since ϵ≤1/4096\epsilon\leq 1/4096.

The smoothed measures are tame and their vv-support avoids zero, so Lemma 10.1 applies. The modulus lemma and the constants in Table 10.3 bound the changes in all reference potentials by

Σq⁢(3⁢ϵ)⁢(1+log⁡(1/(3⁢ϵ))).\Sigma_{q}(3\epsilon)\bigl{(}1+\log(1/(3\epsilon))\bigr{)}.

For the two denominator potentials in the dual fields, each derivative in the field variable is at most LD,qL_{D,q} on the tube. Their total mass coefficient is 5/25/2, so their transfer error is at most CD,q⁢ϵC_{D,q}\epsilon.

For the positive one-body terms, if a real centre t≥δ/2t\geq\delta/2, the circle mean of log⁡|t+2⁢i⁢ϵ+ϵ⁢ei⁢ϑ|\log|t+2i\epsilon+\epsilon e^{i\vartheta}| is log⁡|t+2⁢i⁢ϵ|≤log⁡t+8⁢ϵ2/δ2\log|t+2i\epsilon|\leq\log t+8\epsilon^{2}/\delta^{2}. The combined weighted loss for xx and vv is therefore at most (17/2)⁢ϵ2/δ2(17/2)\epsilon^{2}/\delta^{2}. If t<δ/2t<\delta/2, the whole smearing circle lies in |w|≤δ|w|\leq\delta, so (10.13) gives the endpoint bound directly. For the negative zz one-body term, |z|≥r|z|\geq r, |zϵ−z|≤3⁢ϵ|z^{\epsilon}-z|\leq 3\epsilon, and 3⁢ϵ<r3\epsilon<r give

|log⁡|zϵ|−log⁡|z||≤3⁢ϵr−3⁢ϵ.\left|\log|z^{\epsilon}|-\log|z|\right|\leq\frac{3\epsilon}{r-3\epsilon}.

Consequently,

−54⁢log⁡|zϵ|≤−54⁢log⁡|z|+15⁢ϵ4⁢(r−3⁢ϵ).-\frac{5}{4}\log|z^{\epsilon}|\leq-\frac{5}{4}\log|z|+\frac{15\epsilon}{4(r-3% \epsilon)}.

The centres lie on the certified supports; combining the last three estimates with the endpoint bounds and the directed field bounds yields

log⁡|Φq|m2≤\displaystyle\frac{\log|\Phi_{q}|}{m^{2}}\leq{} −𝒬q⁢(νq)+Kx,q+54⁢Kv,q+Kz,q+134⁢m⁢log⁡(1/ϵ)\displaystyle-\mathcal{Q}_{q}(\nu_{q})+K_{x,q}+\frac{5}{4}K_{v,q}+K_{z,q}+% \frac{13}{4m}\log(1/\epsilon)
+3⁢Σq⁢ϵ⁢(1+log⁡(1/(3⁢ϵ)))+(2⁢CD,q+154⁢(r−3/4096))⁢ϵ+172⁢ϵ2δ2.\displaystyle+3\Sigma_{q}\epsilon\bigl{(}1+\log(1/(3\epsilon))\bigr{)}+\left(2% C_{D,q}+\frac{15}{4(r-3/4096)}\right)\epsilon+\frac{17}{2}\frac{\epsilon^{2}}{% \delta^{2}}.

Here the coefficient 2⁢CD,q2C_{D,q} accounts separately for the denominator in the smoothed energy and in the transferred dual fields. For all q≥2q\geq 2, the rational comparison 100⁢(1+3/4096)<101⁢(2−(1+3/4096)2)100(1+3/4096)<101(2-(1+3/4096)^{2}) gives LD,q<101/100L_{D,q}<101/100, hence CD,q<8.08C_{D,q}<8.08. Also 15/(4⁢(r−3/4096))<715/(4(r-3/4096))<7, and

172⁢δ2⁢m2≤5312504096<130(m≥64).\frac{17}{2\delta^{2}m^{2}}\leq\frac{531250}{4096}<130\qquad(m\geq 64).

The total constant after multiplying by m2m^{2} is therefore less than 16.2+7+130<20016.2+7+130<200.

The path length is exactly 𝒯q\mathcal{T}_{q}. Since q≤7q\leq 7 and e>8/3e>8/3, we have log⁡q<2\log q<2. Also π<22/7\pi<22/7, so π2+log2⁡q<4\sqrt{\pi^{2}+\log^{2}q}<4, whence 𝒯q/q<21/10<e\mathcal{T}_{q}/q<21/10<e. The prefactor in (10.8) contributes (3⁢m2/2−m)⁢log⁡q(3m^{2}/2-m)\log q, and the path contributes m⁢log⁡𝒯qm\log\mathcal{T}_{q}; their linear part is m⁢log⁡(𝒯q/q)≤mm\log(\mathcal{T}_{q}/q)\leq m. Add these terms and drop the favorable −log⁡((m!)2⁢L!)-\log((m!)^{2}L!). With ϵ=m−2\epsilon=m^{-2}, the diagonal term is (13/2)⁢m⁢log⁡m(13/2)m\log m. Also

3⁢Σq⁢(1+log⁡(m2/3))≤3⁢Σq⁢m⁢log⁡m,200≤m⁢log⁡m,m≤14⁢m⁢log⁡m3\Sigma_{q}\bigl{(}1+\log(m^{2}/3)\bigr{)}\leq 3\Sigma_{q}m\log m,\quad 200% \leq m\log m,\quad m\leq\tfrac{1}{4}m\log m

for m≥64m\geq 64. The resulting coefficient is at most 13/2+3⁢Σq+1+1/4<10+3⁢Σq13/2+3\Sigma_{q}+1+1/4<10+3\Sigma_{q}. Finally the definition of αq\alpha_{q} in (10.12) gives (10.14). If the determinant integrand vanishes, the bound holds trivially; otherwise all empirical measures above are defined and the argument applies. This proves the claim for every m=4⁢n≥64m=4n\geq 64, not just for the finite certificate values. ∎

Thus the directed margins and the all-mm analytic estimate are separate inputs: the former supplies αq>τq\alpha_{q}>\tau_{q}, while (10.14) supplies the full quantifier with an explicit finite coefficient for each fixed q=2,…,7q=2,\ldots,7.

11. Seed determinants and eventual nonvanishing

This section proves the nonvanishing input for the determinants used in each of the two constructions. The P0 family has a base-dependent auxiliary prime; the signed construction uses one explicitly listed prime for each base a=−ra=-r, 2≤r≤72\leq r\leq 7. The prime-power variable below is always separate from the base parameter. Finite seed calculations are printed, but nonvanishing at all sufficiently high powers follows from the residue-block identities proved here, not from extrapolating a finite table.

11.1. The P0 seed and its base-dependent prime

Write Gm,a(0)⁢(T)G^{(0)}_{m,a}(T) for the P0 determinant of (4.1). At m=4m=4 its row and column sets are I4={1,2,3,4}I_{4}=\{1,2,3,4\} and J4={0,1,…,7}J_{4}=\{0,1,\ldots,7\}. Exact elimination in this the 8×88\times 8 determinant gives

(11.1) G4,a(0)⁢(0)=a9⁢(a−1)2⁢H⁢(a)D,D=2090188800000=217⁢36⁢55⁢7.G^{(0)}_{4,a}(0)=\frac{a^{9}(a-1)^{2}H(a)}{D},\qquad D=2090188800000=2^{17}3^{% 6}5^{5}7.

For an exact coefficient record, write H⁢(a)=∑j=017hj⁢ajH(a)=\sum_{j=0}^{17}h_{j}a^{j}. In descending degree the vector (h17,…,h0)(h_{17},\ldots,h_{0}) is

(10369949184000000−79502943744000000273672012096000000−559106235072000000754609551358320000−707442931414800000469847663340300000−22036738816008000071443538332097400−157536672046026002634445947232050−48662643111390091676122191935−94737377912904240340492704759882606−445464791296).\left(\begin{array}[]{r}10369949184000000\\ -79502943744000000\\ 273672012096000000\\ -559106235072000000\\ 754609551358320000\\ -707442931414800000\\ 469847663340300000\\ -220367388160080000\\ 71443538332097400\\ -15753667204602600\\ 2634445947232050\\ -486626431113900\\ 91676122191935\\ -9473737791290\\ 424034049270\\ 4759882606\\ -44546479\\ 1296\end{array}\right).

Reduction of this vector gives

(11.2) H⁢(a)≡a2+a+1(mod5).H(a)\equiv a^{2}+a+1\pmod{5}.

The values of the right side at a=0,1,2,3,4a=0,1,2,3,4 are respectively 1,3,2,3,11,3,2,3,1. Thus H⁢(a)≠0H(a)\neq 0 for every integer aa.

Fix any integer aa with |a|≥2|a|\geq 2, and put

Na=10!⁢|a⁢(a−1)⁢H⁢(a)|+1.N_{a}=10!\,|a(a-1)H(a)|+1.

This integer is greater than one. Choose any prime divisor pp of NaN_{a}. Since Na≡1(modℓ)N_{a}\equiv 1\pmod{\ell} for every prime ℓ≤10\ell\leq 10, we have p>10p>10. Also pp divides none of aa, a−1a-1, and H⁢(a)H(a), and p∤Dp\nmid D by the factorization in (11.1). Consequently

(11.3) a,a−1,G4,a(0)⁢(0)are all units in ⁢ℤ(p).a,\quad a-1,\quad G^{(0)}_{4,a}(0)\quad\text{are all units in }\mathbb{Z}_{(p)}.

The choice is allowed to depend on aa; no fixed prime is asserted to work for every base.

11.2. P0 Frobenius blocks

Let Q=pkQ=p^{k} and m=4⁢Qm=4Q. Write each index uniquely as i=Q⁢u+ri=Qu+r with 0≤r<Q0\leq r<Q. The P0 row indices are i=Q,…,5⁢Q−1i=Q,\ldots,5Q-1, and its column indices are j=0,…,8⁢Q−1j=0,\ldots,8Q-1. The following congruence is coefficientwise in ℤ(p)⁢[X]\mathbb{Z}_{(p)}[X]:

(11.4) Q12⁢Q⁢G4⁢Q,a(0)⁢(X/Q2)≡G4,a(0)⁢(X)Q(modp).Q^{12Q}G^{(0)}_{4Q,a}(X/Q^{2})\equiv G^{(0)}_{4,a}(X)^{Q}\pmod{p}.

We give the entry argument, including the denominator and permutation checks. In the P0 determinant, all summation denominators, index differences, and diagonal denominators occurring at level 4⁢Q4Q are nonzero integers whose absolute values are less than 10⁢Q10Q. As p>10p>10, each has pp-adic valuation at most kk; the only other denominators are powers of a−1a-1, which are pp-units by (11.3). Therefore multiplying each CC row by QQ and each B−T⁢AB-TA row by Q2Q^{2} produces a matrix over ℤ(p)⁢[X]\mathbb{Z}_{(p)}[X]. Its determinant is exactly the left side of (11.4).

Lucas’ congruence and aQ≡aa^{Q}\equiv a in 𝔽p\mathbb{F}_{p} give

(Q⁢(u+2)+r2⁢Q)⁢aQ⁢u+r≡ar⁢(u+22)⁢au(modp).\binom{Q(u+2)+r}{2Q}a^{Qu+r}\equiv a^{r}\binom{u+2}{2}a^{u}\pmod{p}.

In the finite sums defining the P0 rows, multiplication by QQ (or Q2Q^{2} on a second-order denominator) kills every summand whose denominator is not divisible by QQ. The surviving summands, after division of their indices by QQ, are exactly the corresponding level-44 sums. For the correction terms this uses (a/(a−1))Q≡a/(a−1)(modp)(a/(a-1))^{Q}\equiv a/(a-1)\pmod{p}. Thus, with u,vu,v denoting the quotient indices and r,sr,s the residues,

(11.5) Q⁢CQ⁢u+r,Q⁢v+s\displaystyle QC_{Qu+r,Qv+s} ≡𝟏r=s⁢ar⁢Cu,v(modp),\displaystyle\equiv\mathbf{1}_{r=s}a^{r}C_{u,v}\pmod{p},
(11.6) Q2⁢BQ⁢u+r,Q⁢v+s\displaystyle Q^{2}B_{Qu+r,Qv+s} ≡𝟏r=s⁢ar⁢Bu,v(modp),\displaystyle\equiv\mathbf{1}_{r=s}a^{r}B_{u,v}\pmod{p},
(11.7) AQ⁢u+r,Q⁢v+s\displaystyle A_{Qu+r,Qv+s} ≡𝟏r=s⁢ar⁢Au,v(modp).\displaystyle\equiv\mathbf{1}_{r=s}a^{r}A_{u,v}\pmod{p}.

For the off-diagonal entries with unequal residues, the first two congruences also follow because vp⁢(j−i)<kv_{p}(j-i)<k, so Q/(j−i)Q/(j-i) is zero modulo pp after localization. When the residues agree, j−i=Q⁢(v−u)j-i=Q(v-u); the reduced nonzero differences satisfy |v−u|≤7<p|v-u|\leq 7<p. The diagonal identities follow by the same denominator filtering in the displayed harmonic sums. This proves (11.7) for every entry, including the diagonals.

After grouping rows and columns by residues, the scaled matrix is block diagonal modulo pp, with QQ blocks

ar⁢[C4⁢(a)B4⁢(a)−X⁢A4⁢(a)],0≤r<Q.a^{r}\begin{bmatrix}C_{4}(a)\\ B_{4}(a)-XA_{4}(a)\end{bmatrix},\qquad 0\leq r<Q.

There are eight rows in each block, so their scalar product is a8⁢∑r=0Q−1r=a4⁢Q⁢(Q−1)a^{8\sum_{r=0}^{Q-1}r}=a^{4Q(Q-1)}. The column regrouping sign is (−1)(Q2)⁢(82)=1(-1)^{\binom{Q}{2}\binom{8}{2}}=1, and interleaving the two four-row families has sign (−1)42⁢(Q2)=1(-1)^{4^{2}\binom{Q}{2}}=1. Since aQ−1≡1(modp)a^{Q-1}\equiv 1\pmod{p}, the scalar product is also 11 modulo pp. Taking determinants proves (11.4).

Lemma 11.1 (P0 eventual nonvanishing).

For every fixed integer aa with |a|≥2|a|\geq 2 and every fixed rational number ξ\xi, there is k0=k0⁢(a,ξ)k_{0}=k_{0}(a,\xi) such that

G4⁢pk,a(0)⁢(ξ)≠0(k≥k0),G^{(0)}_{4p^{k},a}(\xi)\neq 0\qquad(k\geq k_{0}),

where pp is any prime selected as above.

Proof.

Set W=Q2⁢ξW=Q^{2}\xi in the scaled determinant of (11.4). For all sufficiently large kk, vp⁢(W)=2⁢k+vp⁢(ξ)>0v_{p}(W)=2k+v_{p}(\xi)>0 (with the assertion immediate for ξ=0\xi=0). Its left-side scaled matrix is over ℤ(p)\mathbb{Z}_{(p)}, while its determinant reduces modulo pp to

G4,a(0)⁢(0)Q,G^{(0)}_{4,a}(0)^{Q},

which is a unit by (11.3). The scaled determinant is therefore nonzero, and its scaling factor is nonzero; hence G4⁢Q,a(0)⁢(ξ)≠0G^{(0)}_{4Q,a}(\xi)\neq 0. ∎

11.3. Negative V seeds

For a=−ra=-r, 2≤r≤72\leq r\leq 7, write G4⁢n,a(V)⁢(T)G^{(V)}_{4n,a}(T) for the column-VV determinant

G4⁢n,a(V)⁢(T)=det[C⁢(a)B⁢(a)−T⁢A⁢(a)V],G^{(V)}_{4n,a}(T)=\det\begin{bmatrix}C(a)\\ B(a)-TA(a)\\ V\end{bmatrix},

with

I=[2⁢n,6⁢n),J=[n,10⁢n),Λ={1,…,n}.I=[2n,6n),\qquad J=[n,10n),\qquad\Lambda=\{1,\ldots,n\}.
Ci⁢j=ai−ajj−i(i≠j),Ci⁢i=0,Ai⁢j=ai⁢δi⁢j.C_{ij}=\frac{a^{i}-a^{j}}{j-i}\quad(i\neq j),\qquad C_{ii}=0,\qquad A_{ij}=a^{% i}\delta_{ij}.
tj=∑s=1jaj−ss,bj=∑s=1jaj−ss2,t_{j}=\sum_{s=1}^{j}\frac{a^{j-s}}{s},\qquad b_{j}=\sum_{s=1}^{j}\frac{a^{j-s}% }{s^{2}},\qquad
Bi⁢j={(ti−tj)/(j−i),i≠j,bi,i=j,Vℓ⁢j=1j+ℓ.B_{ij}=\begin{cases}(t_{i}-t_{j})/(j-i),&i\neq j,\\ b_{i},&i=j,\end{cases}\qquad V_{\ell j}=\frac{1}{j+\ell}.

Here I,J,ΛI,J,\Lambda are integer intervals, with increasing order. At the seed level n=1n=1, the determinant is 9×99\times 9, with I={2,3,4,5}I=\{2,3,4,5\}, J={1,…,9}J=\{1,\ldots,9\}, and Λ={1}\Lambda=\{1\}. The exact source formulas give the following reductions. Coefficient vectors are in ascending powers of TT; thus each row specifies the entire seed polynomial modulo its indicated prime.

rr aa prp_{r} G4,−r(V)⁢(T)modprG^{(V)}_{4,-r}(T)\bmod p_{r} G4,−r(V)⁢(0)modprG^{(V)}_{4,-r}(0)\bmod p_{r}
2 −2-2 11 (4,2,7,3,9)(4,2,7,3,9) 4
3 −3-3 11 (1,4,6,7,1)(1,4,6,7,1) 1
4 −4-4 23 (5,8,16,21,20)(5,8,16,21,20) 5
5 −5-5 11 (5,2,5,8,7)(5,2,5,8,7) 5
6 −6-6 17 (5,12,4,7,4)(5,12,4,7,4) 5
7 −7-7 17 (8,0,8,16,5)(8,0,8,16,5) 8

For example, the first vector means 4+2⁢T+7⁢T2+3⁢T3+9⁢T44+2T+7T^{2}+3T^{3}+9T^{4} in 𝔽11⁢[T]\mathbb{F}_{11}[T]. All six constant entries are nonzero. Each prp_{r} exceeds 77. The individual seed entries have denominators dividing 252022520^{2}, and hence every coefficient denominator of the seed determinant is supported on the primes 2,3,5,72,3,5,7 (cancellation may make it smaller, but need not make it divide 252022520^{2}). Thus prp_{r} is prime to every seed denominator, to aa, and to a−1a-1. The seed constant is consequently a prp_{r}-adic unit and all seed coefficients are defined in ℤ(pr)\mathbb{Z}_{(p_{r})}.

11.4. Signed Frobenius blocks

Fix rr and abbreviate p=prp=p_{r}. Put Q=pkQ=p^{k} and m=4⁢Qm=4Q. At this level the three shape parameters of the V source are all set equal to QQ; they are distinct from the exponent kk in Q=pkQ=p^{k}. Then the row and column intervals are

I=[2⁢Q,6⁢Q),J=[Q,10⁢Q),Λ={1,…,Q}.I=[2Q,6Q),\qquad J=[Q,10Q),\qquad\Lambda=\{1,\ldots,Q\}.

Define

(11.8) Pr,k⁢(X)=Q3⁢m+Q⁢Gm,−r(V)⁢(X/Q2)=Q13⁢Q⁢G4⁢Q,−r(V)⁢(X/Q2).P_{r,k}(X)=Q^{3m+Q}G^{(V)}_{m,-r}(X/Q^{2})=Q^{13Q}G^{(V)}_{4Q,-r}(X/Q^{2}).

The determinant on the left is formed by scaling its CC and VV rows by QQ and its B−T⁢AB-TA rows by Q2Q^{2}; the middle rows become Q2⁢B−X⁢AQ^{2}B-XA. Every nonzero denominator in a harmonic sum, index difference, or V-entry is an integer whose absolute value is less than 11⁢Q11Q. Since p≥11p\geq 11, its pp-adic valuation is at most kk. Hence the scaled matrix has entries in ℤ(p)⁢[X]\mathbb{Z}_{(p)}[X], and so does Pr,k⁢(X)P_{r,k}(X).

Write i=Q⁢i0+ui=Qi_{0}+u and j=Q⁢j0+vj=Qj_{0}+v, with residues in {0,…,Q−1}\{0,\ldots,Q-1\}. As in the P0 calculation, only summands with denominator divisible by QQ survive after row scaling. In particular,

(11.9) Q⁢tQ⁢j0+u≡au⁢tj0,Q2⁢bQ⁢j0+u≡au⁢bj0(modp),Qt_{Qj_{0}+u}\equiv a^{u}t_{j_{0}},\qquad Q^{2}b_{Qj_{0}+u}\equiv a^{u}b_{j_{0% }}\pmod{p},

because aQ≡a(modp)a^{Q}\equiv a\pmod{p}. For CC and the off-diagonal BB entries, unequal residues vanish: if u≠vu\neq v, then vp⁢(j−i)<kv_{p}(j-i)<k. With equal residues and unequal quotient indices, division by j−i=Q⁢(j0−i0)j-i=Q(j_{0}-i_{0}) gives the seed CC and BB entries with row factor aua^{u}; here |j0−i0|≤7<p|j_{0}-i_{0}|\leq 7<p. The diagonal BB entry follows from (11.9). The diagonal AA entries satisfy AQ⁢i0+u,Q⁢i0+u≡au⁢Ai0⁢i0(modp)A_{Qi_{0}+u,Qi_{0}+u}\equiv a^{u}A_{i_{0}i_{0}}\pmod{p}.

For the V rows, fix a column residue uu. There is exactly one ℓ∈{1,…,Q}\ell\in\{1,\ldots,Q\} with ℓ+u≡0(modQ)\ell+u\equiv 0\pmod{Q}, namely ℓ=Q−u\ell=Q-u when u>0u>0 and ℓ=Q\ell=Q when u=0u=0. All other scaled entries vanish modulo pp, and for this row

Qj+ℓ=1j0+1,\frac{Q}{j+\ell}=\frac{1}{j_{0}+1},

the seed V-entry. Thus residue regrouping gives QQ diagonal blocks

[au⁢C4au⁢(B4−X⁢A4)V4],0≤u<Q.\begin{bmatrix}a^{u}C_{4}\\ a^{u}(B_{4}-XA_{4})\\ V_{4}\end{bmatrix},\qquad 0\leq u<Q.

Each block has eight rows carrying aua^{u} and one V row. Row and column regrouping contributes a sign εr,k∈{1,−1}\varepsilon_{r,k}\in\{1,-1\}, which is a pp-adic unit and need not be evaluated. Therefore, coefficientwise,

(11.10) Pr,k⁢(X)≡εr,k⁢a4⁢Q⁢(Q−1)⁢G4,−r(V)⁢(X)Q(modp).P_{r,k}(X)\equiv\varepsilon_{r,k}a^{4Q(Q-1)}G^{(V)}_{4,-r}(X)^{Q}\pmod{p}.

The exponent is 8⁢∑u=0Q−1u=4⁢Q⁢(Q−1)8\sum_{u=0}^{Q-1}u=4Q(Q-1). The table above shows p∤G4,−r(V)⁢(0)p\nmid G^{(V)}_{4,-r}(0), and p∤ap\nmid a, so the constant coefficient on the right of (11.10) is nonzero modulo pp.

Lemma 11.2 (negative-base eventual nonvanishing).

For each r∈{2,3,4,5,6,7}r\in\{2,3,4,5,6,7\} and every fixed rational number ξ\xi, there is k0=k0⁢(r,ξ)k_{0}=k_{0}(r,\xi) such that

G4⁢prk,−r(V)⁢(ξ)≠0(k≥k0).G^{(V)}_{4p_{r}^{k},-r}(\xi)\neq 0\qquad(k\geq k_{0}).
Proof.

Use the convention vpr⁢(0)=+∞v_{p_{r}}(0)=+\infty. For all sufficiently large kk, vpr⁢(Q2⁢ξ)=2⁢k+vpr⁢(ξ)>0v_{p_{r}}(Q^{2}\xi)=2k+v_{p_{r}}(\xi)>0 (and this is immediate when ξ=0\xi=0). Since Pr,k∈ℤ(pr)⁢[X]P_{r,k}\in\mathbb{Z}_{(p_{r})}[X], its value at X=Q2⁢ξX=Q^{2}\xi is congruent modulo prp_{r} to its constant coefficient. By (11.10), that coefficient is a unit. Thus Pr,k⁢(Q2⁢ξ)≠0P_{r,k}(Q^{2}\xi)\neq 0, and the nonzero scaling in (11.8) yields the claim. ∎

11.5. Use in the determinant criterion

For a fixed rational target ξ\xi, the preceding lemmas give nonvanishing at every sufficiently high index of the selected prime-power sequence, not merely at one computed level. Once k≥k0k\geq k_{0}, the determinants at indices kk and k+1k+1 are both nonzero. This assertion concerns the selected prime-power subsequence only; no nonvanishing assertion is made for every intervening integer degree mm.

For each fixed integer base, the irrationality criterion of Section 3 must now be applied to one family at a time: P0 with its base-dependent prime, or V with the corresponding prp_{r}. The integerizer, analytic estimate, and nonzero determinant must all belong to that same source. The prime-power sequences proved here supply exactly the nonzero term required by the criterion; they do not by themselves imply a common analytic or arithmetic rate across the two families.

12. Hermite–Padé tails

This section proves the two tails from the displayed construction, without using an irrationality theorem as input. The base is fixed throughout each limit; constants in contour and remainder estimates may depend on that base.

Theorem 12.1.

For every fixed integer a≥12a\geq 12 or a≤−8a\leq-8, the determinant construction below proves that Li2⁡(1/a)\operatorname{Li}_{2}(1/a) is irrational.

12.1. Residues, tails, and exact integerization

For n≥0n\geq 0 put

(12.1) Φn⁢(w)=∏r=n+13⁢n+1(w−r)∏j=0n(w−j)2=∑j=0n(un,j(w−j)2+vn,jw−j).\Phi_{n}(w)=\frac{\prod_{r=n+1}^{3n+1}(w-r)}{\prod_{j=0}^{n}(w-j)^{2}}=\sum_{j% =0}^{n}\left(\frac{u_{n,j}}{(w-j)^{2}}+\frac{v_{n,j}}{w-j}\right).

Writing Hk=∑r=1k1/rH_{k}=\sum_{r=1}^{k}1/r and H0=0H_{0}=0, direct residue calculation gives

(12.2) un,j=−(3⁢n+1−j)!(j!)2⁢((n−j)!)3,vn,j=un,j⁢(3⁢Hn−j−2⁢Hj−H3⁢n+1−j).u_{n,j}=-\frac{(3n+1-j)!}{(j!)^{2}((n-j)!)^{3}},\qquad v_{n,j}=u_{n,j}\bigl{(}% 3H_{n-j}-2H_{j}-H_{3n+1-j}\bigr{)}.

Set

Bn⁢(z)=∑j=0nvn,j⁢zj,Cn⁢(z)=∑j=0nun,j⁢zj,B_{n}(z)=\sum_{j=0}^{n}v_{n,j}z^{j},\qquad C_{n}(z)=\sum_{j=0}^{n}u_{n,j}z^{j},

and

An⁢(z)=−∑k=1nzk⁢∑j=0k−1(vn,jk−j+un,j(k−j)2).A_{n}(z)=-\sum_{k=1}^{n}z^{k}\sum_{j=0}^{k-1}\left(\frac{v_{n,j}}{k-j}+\frac{u% _{n,j}}{(k-j)^{2}}\right).

The coefficient of zkz^{k} in Bn⁢(−log⁡(1−z))+Cn⁢Li2⁡(z)B_{n}(-\log(1-z))+C_{n}\operatorname{Li}_{2}(z) is the partial-fraction sum ∑j<k(vn,j/(k−j)+un,j/(k−j)2)\sum_{j<k}(v_{n,j}/(k-j)+u_{n,j}/(k-j)^{2}). For 1≤k≤n1\leq k\leq n it is canceled by AnA_{n}; for n<k≤3⁢n+1n<k\leq 3n+1 it is zero because Φn⁢(k)=0\Phi_{n}(k)=0; for k≥3⁢n+2k\geq 3n+2 it equals Φn⁢(k)\Phi_{n}(k). Therefore

(12.3) Rn⁢(z):=An⁢(z)+Bn⁢(z)⁢(−log⁡(1−z))+Cn⁢(z)⁢Li2⁡(z)=∑k≥3⁢n+2Φn⁢(k)⁢zk.R_{n}(z):=A_{n}(z)+B_{n}(z)(-\log(1-z))+C_{n}(z)\operatorname{Li}_{2}(z)=\sum_% {k\geq 3n+2}\Phi_{n}(k)z^{k}.

The adjacent Casoratian

(12.4) En⁢(z):=Bn+1⁢(z)⁢Rn⁢(z)−Bn⁢(z)⁢Rn+1⁢(z)=Wn⁢(z)+Vn⁢(z)⁢Li2⁡(z)E_{n}(z):=B_{n+1}(z)R_{n}(z)-B_{n}(z)R_{n+1}(z)=W_{n}(z)+V_{n}(z)\operatorname% {Li}_{2}(z)

has

Wn=Bn+1⁢An−Bn⁢An+1,Vn=Bn+1⁢Cn−Bn⁢Cn+1.W_{n}=B_{n+1}A_{n}-B_{n}A_{n+1},\qquad V_{n}=B_{n+1}C_{n}-B_{n}C_{n+1}.

The logarithm cancels identically. Both Wn,VnW_{n},V_{n} have degree at most N=2⁢n+1N=2n+1.

Here is an all-degree proof of the coefficient formula needed for integerization. Let bn=(2⁢n+1n)b_{n}=\binom{2n+1}{n} and

Jn⁢(t)=∑k=0N(−1)k⁢(Nk)⁢(n+kk)2⁢tk.J_{n}(t)=\sum_{k=0}^{N}(-1)^{k}\binom{N}{k}\binom{n+k}{k}^{\!2}t^{k}.

For ℜ⁡(s)>−1\Re(s)>-1 the integral is absolutely convergent, and direct termwise integration gives

(12.5) ∫01ts⁢Jn⁢(t)⁢𝑑t=(2⁢n+1)!(n!)2⁢[s⁢(s−1)⁢⋯⁢(s−n+1)]2(s+1)⁢(s+2)⁢⋯⁢(s+2⁢n+2).\int_{0}^{1}t^{s}J_{n}(t)\,dt=\frac{(2n+1)!}{(n!)^{2}}\frac{[s(s-1)\cdots(s-n+% 1)]^{2}}{(s+1)(s+2)\cdots(s+2n+2)}.

The right side then supplies the meromorphic continuation in ss; no continuation is used before the stated half-plane of convergence. Write Vn⁢(z)=∑i=0Nvi⁢ziV_{n}(z)=\sum_{i=0}^{N}v_{i}z^{i} and Πn⁢(t)=tN⁢Vn⁢(1/t)=∑j=0Nπj⁢tj\Pi_{n}(t)=t^{N}V_{n}(1/t)=\sum_{j=0}^{N}\pi_{j}t^{j}, so πj=vN−j\pi_{j}=v_{N-j}. The polynomial part of EnE_{n} has degree at most NN. For k=N+ℓk=N+\ell, 1≤ℓ≤n1\leq\ell\leq n, its coefficient is therefore

0=∑i=0Nvi(k−i)2=∑j=0Nπj(ℓ+j)2,0=\sum_{i=0}^{N}\frac{v_{i}}{(k-i)^{2}}=\sum_{j=0}^{N}\frac{\pi_{j}}{(\ell+j)^% {2}},

which is −∫01tℓ−1⁢Πn⁢(t)⁢log⁡t⁢d⁢t=0-\int_{0}^{1}t^{\ell-1}\Pi_{n}(t)\log t\,dt=0. The second elimination, Cn+1⁢Rn−Cn⁢Rn+1C_{n+1}R_{n}-C_{n}R_{n+1}, cancels Li2\operatorname{Li}_{2}; its nonpolynomial part is Vn⁢(z)⁢log⁡(1−z)V_{n}(z)\log(1-z). The same coefficient range gives

0=∑i=0Nvik−i=∑j=0Nπjℓ+j=∫01tℓ−1⁢Πn⁢(t)⁢𝑑t.0=\sum_{i=0}^{N}\frac{v_{i}}{k-i}=\sum_{j=0}^{N}\frac{\pi_{j}}{\ell+j}=\int_{0% }^{1}t^{\ell-1}\Pi_{n}(t)\,dt.

Thus the two exact moment families are

(12.6) ∫01tj⁢Πn⁢(t)⁢𝑑t=0,∫01tj⁢Πn⁢(t)⁢log⁡t⁢d⁢t=0(0≤j<n).\int_{0}^{1}t^{j}\Pi_{n}(t)\,dt=0,\qquad\int_{0}^{1}t^{j}\Pi_{n}(t)\log t\,dt=% 0\quad(0\leq j<n).

The Mellin transform of any polynomial of degree at most NN has denominator ∏r=1N+1(s+r)\prod_{r=1}^{N+1}(s+r) and numerator degree at most NN. The first family in (12.6) makes this numerator vanish at s=0,…,n−1s=0,\ldots,n-1; the second makes each zero double. Hence the numerator is divisible by [s⁢(s−1)⁢⋯⁢(s−n+1)]2[s(s-1)\cdots(s-n+1)]^{2}, leaving a factor of degree at most one. The solution space of (12.6) consequently has dimension at most two.

Equation (12.5) shows that JnJ_{n} is one solution. It also shows Jn⁢(1)=0J_{n}(1)=0, since the right side is O⁢(s−2)O(s^{-2}) as s→+∞s\to+\infty. Integration by parts then shows that t⁢Jn′⁢(t)tJ_{n}^{\prime}(t) is a second solution: the boundary terms vanish at both endpoints, and the two moment families for t⁢Jn′tJ^{\prime}_{n} reduce to those for JnJ_{n}. The two solutions are independent by their top two coefficients: if aN=[tN]⁢Jna_{N}=[t^{N}]J_{n} and aN−1=[tN−1]⁢Jna_{N-1}=[t^{N-1}]J_{n}, the determinant formed from the top two coefficients of JnJ_{n} and t⁢Jn′tJ_{n}^{\prime} is aN⁢(N−1)⁢aN−1−N⁢aN⁢aN−1=−aN⁢aN−1≠0a_{N}(N-1)a_{N-1}-Na_{N}a_{N-1}=-a_{N}a_{N-1}\neq 0. Thus every solution is their linear combination. Direct substitution of the residues (12.2) gives the constant and linear coefficients of Πn\Pi_{n}; matching those two coefficients in this two-dimensional space yields

(12.7) Vn⁢(z)=bn2⁢zN⁢Pn⁢(1/z),V_{n}(z)=b_{n}^{2}z^{N}P_{n}(1/z),

where

(12.8) Pn⁢(t)=−∑k=0N(−1)k⁢(Nk)⁢(n+kk)⁢((12⁢n+17)⁢(n+kk)+(21⁢n+29)⁢(n+kk−1))⁢tk.P_{n}(t)=-\sum_{k=0}^{N}(-1)^{k}\binom{N}{k}\binom{n+k}{k}\left((12n+17)\binom% {n+k}{k}+(21n+29)\binom{n+k}{k-1}\right)t^{k}.

The convention is (n+kk−1)=0\binom{n+k}{k-1}=0 at k=0k=0. In particular, the second binomial is (n+kk−1)\binom{n+k}{k-1}, not (n+k−1k−1)\binom{n+k-1}{k-1}.

The first two coefficients follow from the endpoint residues. Put ηm=−2⁢Hm−H2⁢m+1\eta_{m}=-2H_{m}-H_{2m+1}, ρm=2⁢m2⁢(m+1)\rho_{m}=2m^{2}(m+1), and κm=3+2/m−1/(2⁢m+2)\kappa_{m}=3+2/m-1/(2m+2). Their ratios are

vm,mum,m=ηm,um,m−1um,m=ρm,vm,m−1um,m−1=ηm+κm.\frac{v_{m,m}}{u_{m,m}}=\eta_{m},\qquad\frac{u_{m,m-1}}{u_{m,m}}=\rho_{m},% \qquad\frac{v_{m,m-1}}{u_{m,m-1}}=\eta_{m}+\kappa_{m}.

For n≥1n\geq 1, expanding Vn=Bn+1⁢Cn−Bn⁢Cn+1V_{n}=B_{n+1}C_{n}-B_{n}C_{n+1} at its top two degrees yields, with πj=[tj]⁢Πn\pi_{j}=[t^{j}]\Pi_{n},

π0\displaystyle\pi_{0} =un,n⁢un+1,n+1⁢(ηn+1−ηn),\displaystyle=u_{n,n}u_{n+1,n+1}(\eta_{n+1}-\eta_{n}),
π1\displaystyle\pi_{1} =un,n⁢un+1,n+1⁢((ρn+ρn+1)⁢(ηn+1−ηn)−ρn⁢κn+ρn+1⁢κn+1).\displaystyle=u_{n,n}u_{n+1,n+1}\bigl{(}(\rho_{n}+\rho_{n+1})(\eta_{n+1}-\eta_% {n})-\rho_{n}\kappa_{n}+\rho_{n+1}\kappa_{n+1}\bigr{)}.

Here un,n=−(n+1)⁢bnu_{n,n}=-(n+1)b_{n}, un+1,n+1=−2⁢(2⁢n+3)⁢bnu_{n+1,n+1}=-2(2n+3)b_{n}, and ηn+1−ηn=−5/(2⁢(n+1))−1/(2⁢n+3)\eta_{n+1}-\eta_{n}=-5/(2(n+1))-1/(2n+3). Substitution yields π0=−bn2⁢(12⁢n+17)\pi_{0}=-b_{n}^{2}(12n+17) and

π1=bn2⁢(2⁢n+1)⁢(n+1)⁢((n+1)⁢(12⁢n+17)+(21⁢n+29)).\pi_{1}=b_{n}^{2}(2n+1)(n+1)\bigl{(}(n+1)(12n+17)+(21n+29)\bigr{)}.

For n=0n=0, the residues give the same formulas directly: π0=−17\pi_{0}=-17 and π1=46\pi_{1}=46. For the Casoratian calculation below, put hm=3⁢Hm−H3⁢m+1h_{m}=3H_{m}-H_{3m+1} and

δm=hm+1−hm=2⁢(27⁢m2+54⁢m+23)3⁢(m+1)⁢(3⁢m+2)⁢(3⁢m+4),\delta_{m}=h_{m+1}-h_{m}=\frac{2(27m^{2}+54m+23)}{3(m+1)(3m+2)(3m+4)},

The values of π0,π1\pi_{0},\pi_{1} are the first two coefficients of −(12⁢n+17)⁢Jn−(21⁢n+29)⁢t⁢Jn′/(n+1)-(12n+17)J_{n}-(21n+29)tJ^{\prime}_{n}/(n+1). The identity kn+1⁢(n+kk)=(n+kk−1)\frac{k}{n+1}\binom{n+k}{k}=\binom{n+k}{k-1} gives (12.8). The dimension bound proves (12.7) for every nn, with no finite-range restriction.

For reference, the boundary residues used in this matching can be checked directly from (12.2). For m≥1m\geq 1,

(12.9) um,m−1\displaystyle u_{m,m-1} =−(2⁢m+2)!((m−1)!)2,um,m=−(2⁢m+1)!(m!)2,\displaystyle=-\frac{(2m+2)!}{((m-1)!)^{2}},\qquad u_{m,m}=-\frac{(2m+1)!}{(m!% )^{2}},
(12.10) um,m−1um,m\displaystyle\frac{u_{m,m-1}}{u_{m,m}} =(2⁢m+2)⁢m2=2⁢m2⁢(m+1),\displaystyle=(2m+2)m^{2}=2m^{2}(m+1),
(12.11) vm,m−1um,m−1−vm,mum,m\displaystyle\frac{v_{m,m-1}}{u_{m,m-1}}-\frac{v_{m,m}}{u_{m,m}} =3+2m−12⁢m+2,\displaystyle=3+\frac{2}{m}-\frac{1}{2m+2},
(12.12) un,n⁢un+1,n+1bn2\displaystyle\frac{u_{n,n}u_{n+1,n+1}}{b_{n}^{2}} =(2⁢n+2)⁢(2⁢n+3).\displaystyle=(2n+2)(2n+3).

These identities also cover the boundary-residue normalization in the three-form extraction below; the case n=0n=0 is read directly from (12.2).

Let dN=lcm⁡(1,…,N)d_{N}=\operatorname{lcm}(1,\ldots,N) and Qn⁢(z)=Vn⁢(z)/bn2∈ℤ⁢[z]Q_{n}(z)=V_{n}(z)/b_{n}^{2}\in\mathbb{Z}[z]. Since En=Wn+Vn⁢Li2E_{n}=W_{n}+V_{n}\operatorname{Li}_{2} vanishes through degree NN, its polynomial part satisfies

Wn⁢(z)bn2=−[Qn⁢(z)⁢Li2⁡(z)]≤N.\frac{W_{n}(z)}{b_{n}^{2}}=-[Q_{n}(z)\operatorname{Li}_{2}(z)]_{\leq N}.

Each coefficient on the right has denominators among r2r^{2} with 1≤r≤N1\leq r\leq N, and r∣dNr\mid d_{N}. Therefore

(12.13) dN2bn2⁢Wn,dN2bn2⁢Vn∈ℤ⁢[z].\frac{d_{N}^{2}}{b_{n}^{2}}W_{n},\quad\frac{d_{N}^{2}}{b_{n}^{2}}V_{n}\in% \mathbb{Z}[z].

For every fixed integer aa with |a|≥2|a|\geq 2, put

(12.14) Ln⁢(a)=aN⁢dN2bn2⁢En⁢(1/a)=Xn⁢(a)+Yn⁢(a)⁢Li2⁡(1/a),Xn⁢(a),Yn⁢(a)∈ℤ.L_{n}(a)=a^{N}\frac{d_{N}^{2}}{b_{n}^{2}}E_{n}(1/a)=X_{n}(a)+Y_{n}(a)% \operatorname{Li}_{2}(1/a),\qquad X_{n}(a),Y_{n}(a)\in\mathbb{Z}.

The factor aNa^{N} clears evaluation denominators because both polynomials in (12.13) have degree at most NN.

12.2. Remainder bound for both signs

For −1<z<1-1<z<1, beta integration of (12.3) gives the exact identity

(12.15) Rn⁢(z)=(2⁢n+1)!(n!)2⁢z3⁢n+2⁢∫01∫01t⁢u(1−z⁢t⁢u)2⁢(t2⁢u2⁢(1−t)⁢(1−u)(1−z⁢t⁢u)2)n⁢𝑑t⁢𝑑u.R_{n}(z)=\frac{(2n+1)!}{(n!)^{2}}z^{3n+2}\int_{0}^{1}\!\int_{0}^{1}\frac{tu}{(% 1-ztu)^{2}}\left(\frac{t^{2}u^{2}(1-t)(1-u)}{(1-ztu)^{2}}\right)^{n}dt\,du.

To maximize the bracket, fix p=t⁢up=tu. Since t+u≥2⁢pt+u\geq 2\sqrt{p}, (1−t)⁢(1−u)=1−(t+u)+p≤(1−p)2(1-t)(1-u)=1-(t+u)+p\leq(1-\sqrt{p})^{2}, with equality only at t=u=pt=u=\sqrt{p}. Write s=ps=\sqrt{p}. The bracket is at most

gz⁢(s)=s4⁢(1−s)2(1−z⁢s2)2,0≤s≤1.g_{z}(s)=\frac{s^{4}(1-s)^{2}}{(1-zs^{2})^{2}},\qquad 0\leq s\leq 1.

For |z|<1|z|<1, its unique interior maximum satisfies z⁢s3−3⁢s+2=0zs^{3}-3s+2=0: differentiating log⁡gz\log g_{z} gives 2−3⁢s+z⁢s3=02-3s+zs^{3}=0, and the left side is strictly decreasing on [0,1][0,1]. At that root, 1−z⁢s2=2⁢(1−s)/s1-zs^{2}=2(1-s)/s, so gz⁢(s)=s6/4g_{z}(s)=s^{6}/4. The prefactor t⁢u/(1−z⁢t⁢u)2tu/(1-ztu)^{2} in (12.15) is bounded for fixed zz with |z|<1|z|<1. Stirling’s formula [13] and the unit area of the square therefore give

(12.16) lim supn→∞|Rn⁢(z)|1/n≤|z|3⁢s⁢(z)6.\limsup_{n\to\infty}|R_{n}(z)|^{1/n}\leq|z|^{3}s(z)^{6}.

No cancellation estimate is used.

12.3. Positive coefficient bound

For z=1/qz=1/q, q>1q>1, all un,ju_{n,j} have the same (negative) sign. Put x=j/nx=j/n and

fq⁢(x)=(3−x)⁢log⁡(3−x)−2⁢x⁢log⁡x−3⁢(1−x)⁢log⁡(1−x)−x⁢log⁡q,0≤x≤1,f_{q}(x)=(3-x)\log(3-x)-2x\log x-3(1-x)\log(1-x)-x\log q,\quad 0\leq x\leq 1,

where 0⁢log⁡0=00\log 0=0. Uniform Stirling estimates [13] in (12.2) give

log⁡(|un,j|⁢q−j)=n⁢fq⁢(j/n)+O⁢(log⁡(n+1))\log\bigl{(}|u_{n,j}|q^{-j}\bigr{)}=nf_{q}(j/n)+O(\log(n+1))

uniformly for 0≤j≤n0\leq j\leq n. Indeed, the coefficients of n⁢log⁡nn\log n and nn cancel, and all factorial contributions are O⁢(log⁡(n+1))O(\log(n+1)), including at endpoints. Now

fq′⁢(x)=log⁡(1−x)3q⁢x2⁢(3−x),fq′′⁢(x)=13−x−2x−31−x<0.f_{q}^{\prime}(x)=\log\frac{(1-x)^{3}}{qx^{2}(3-x)},\qquad f_{q}^{\prime\prime% }(x)=\frac{1}{3-x}-\frac{2}{x}-\frac{3}{1-x}<0.

There is a unique maximizer t⁢(q)∈(0,1)t(q)\in(0,1), determined by (1−t)3=q⁢t2⁢(3−t)(1-t)^{3}=qt^{2}(3-t). Substitution of this equation gives

exp⁡(fq⁢(t))=(3−t1−t)3.\exp(f_{q}(t))=\left(\frac{3-t}{1-t}\right)^{3}.

Since the sum has only n+1n+1 terms,

lim supn→∞|Cn⁢(1/q)|1/n≤(3−t⁢(q)1−t⁢(q))3.\limsup_{n\to\infty}|C_{n}(1/q)|^{1/n}\leq\left(\frac{3-t(q)}{1-t(q)}\right)^{% 3}.

Also |3⁢Hn−j−2⁢Hj−H3⁢n+1−j|≤6⁢(1+log⁡(3⁢n+1))|3H_{n-j}-2H_{j}-H_{3n+1-j}|\leq 6(1+\log(3n+1)), so the same bound holds for Bn⁢(1/q)B_{n}(1/q). This upper-bound form of the discrete Laplace principle is all that is needed; no unproved ratio limit is used.

12.4. Negative coefficient bound: contour and endpoint estimate

Fix q>1q>1, put z=−1/qz=-1/q, and define the two logarithmic branches

Fn±⁢(z)=Bn⁢(z)+Cn⁢(z)⁢(−log⁡q±i⁢π).F_{n}^{\pm}(z)=B_{n}(z)+C_{n}(z)(-\log q\pm i\pi).

Residues of Φn⁢(w)⁢e(−log⁡q±i⁢π)⁢w\Phi_{n}(w)e^{(-\log q\pm i\pi)w} give

(12.17) Fn±⁢(z)=12⁢π⁢i⁢∮Γn±Φn⁢(w)⁢e(−log⁡q±i⁢π)⁢w⁢𝑑w,F_{n}^{\pm}(z)=\frac{1}{2\pi i}\oint_{\Gamma_{n}^{\pm}}\Phi_{n}(w)e^{(-\log q% \pm i\pi)w}\,dw,

where the rectangle encloses the poles 0,1,…,n0,1,\ldots,n. Set βq>0\beta_{q}>0 equal to the absolute imaginary part of the lower nonreal root of

(12.18) pq⁢(w)=(q+1)⁢w3−3⁢(q+1)⁢w2+3⁢w−1=0.p_{q}(w)=(q+1)w^{3}-3(q+1)w^{2}+3w-1=0.

For all sufficiently large nn, let Γn+\Gamma_{n}^{+} be the positively oriented rectangle with vertical sides ℜ⁡w=−1/2,n+1/2\Re w=-1/2,n+1/2 and horizontal sides ℑ⁡w=±n⁢βq\Im w=\pm n\beta_{q}. It encloses precisely the poles 0,1,…,n0,1,\ldots,n. Its distance from each enclosed pole is at least min⁡{1/2,n⁢βq}\min\{1/2,n\beta_{q}\}, hence at least 1/21/2 once n⁢βq≥1/2n\beta_{q}\geq 1/2. All numerator zeros lie outside the rectangle at distance at least 1/21/2. The rate proof uses only these sufficiently large indices. For Fn−F_{n}^{-} use the conjugate exponential branch on the same positively oriented rectangle.

We give the uniform sum-to-integral estimate needed on these contours. If ξ=w/n\xi=w/n lies on the scaled rectangle, then

(12.19) log⁡|Φn⁢(n⁢ξ)|=n⁢(∫13log⁡|ξ−r|⁢d⁢r−2⁢∫01log⁡|ξ−r|⁢d⁢r)+Oq⁢(log⁡(n+1)),\log|\Phi_{n}(n\xi)|=n\left(\int_{1}^{3}\log|\xi-r|\,dr-2\int_{0}^{1}\log|\xi-% r|\,dr\right)+O_{q}(\log(n+1)),

uniformly along all four sides. On a horizontal side |ℑ⁡ξ|=βq|\Im\xi|=\beta_{q}, the functions r↦log⁡|ξ−r|r\mapsto\log|\xi-r| have uniformly bounded derivative, so the ordinary left/right Riemann-sum error is Oq⁢(1)O_{q}(1). On the left vertical side ℜ⁡ξ=−1/(2⁢n)\Re\xi=-1/(2n), the real part lies outside both integration intervals by at least 1/(2⁢n)1/(2n). On the right side ℜ⁡ξ=1+1/(2⁢n)\Re\xi=1+1/(2n) it lies outside [0,1][0,1] by the same amount. For [1,3][1,3] there, the only possible near-singularity lies in the first mesh cell: its real part is exactly halfway between the endpoint and the first mesh point. If |ℑ⁡ξ|≤1/n|\Im\xi|\leq 1/n, rescaling this one cell by r=1+u/nr=1+u/n shows that both its mesh contribution and nn times its integral are O⁢(log⁡(n+1))O(\log(n+1)); the integral of log⁡u2+v2\log\sqrt{u^{2}+v^{2}} over a fixed interval is bounded uniformly for 0≤v≤10\leq v\leq 1. If |ℑ⁡ξ|>1/n|\Im\xi|>1/n, or on the remaining cells, the total variation is bounded by Cq+∫1/nOq⁢(1)𝑑r/r=Oq⁢(log⁡(n+1))C_{q}+\int_{1/n}^{O_{q}(1)}dr/r=O_{q}(\log(n+1)). Endpoint shifts of one mesh point in the numerator product contribute at most another Oq⁢(log⁡(n+1))O_{q}(\log(n+1)). This proves (12.19); in particular the logarithmic singularity is handled explicitly rather than hidden in a smooth-function Euler–Maclaurin assertion.

For completeness, the estimate in (12.19) is a bounded-variation Riemann-sum estimate, including the endpoint cell. Put fξ⁢(r)=log⁡|ξ−r|f_{\xi}(r)=\log|\xi-r|. The numerator sum is the right Riemann sum on [1,3][1,3], with the extra point fξ⁢(3+1/n)f_{\xi}(3+1/n), and the denominator sum is the right Riemann sum on [0,1][0,1], with fξ⁢(0)f_{\xi}(0). On a horizontal edge the total variation is Oq⁢(1)O_{q}(1). On a vertical edge the only possible singular cell is the first half-mesh cell; after r=1+u/nr=1+u/n (or r=u/nr=u/n) its mesh term and its nn-scaled integral are O⁢(log⁡(n+1))O(\log(n+1)). The remaining variation is Oq⁢(1)+∫1/nOq⁢(1)𝑑r/r=Oq⁢(log⁡(n+1))O_{q}(1)+\int_{1/n}^{O_{q}(1)}dr/r=O_{q}(\log(n+1)). Thus the estimate is uniform on all four edges and does not invoke a smooth Euler–Maclaurin formula across a logarithmic endpoint.

Combining (12.19) with the exact modulus of the exponential factor gives

log⁡|Φn⁢(n⁢ξ)⁢e(−log⁡q+i⁢π)⁢n⁢ξ|=n⁢Hq⁢(ξ)+Oq⁢(log⁡(n+1)),\log|\Phi_{n}(n\xi)e^{(-\log q+i\pi)n\xi}|=nH_{q}(\xi)+O_{q}(\log(n+1)),

where

(12.20) Hq⁢(ξ)=∫13log⁡|ξ−r|⁢d⁢r−2⁢∫01log⁡|ξ−r|⁢d⁢r−log⁡q⁢ℜ⁡ξ−π⁢ℑ⁡ξ.H_{q}(\xi)=\int_{1}^{3}\log|\xi-r|\,dr-2\int_{0}^{1}\log|\xi-r|\,dr-\log q\,% \Re\xi-\pi\Im\xi.

The discriminant of (12.18) is −108⁢q2⁢(q+1)<0-108q^{2}(q+1)<0, and pq⁢(2)=1−4⁢q<0<pq⁢(3)=8p_{q}(2)=1-4q<0<p_{q}(3)=8. Thus the real root is in (2,3)(2,3); the conjugate roots have real part u=(3−R)/2∈(0,1/2)u=(3-R)/2\in(0,1/2). Write the lower root as ξ0=u−i⁢βq\xi_{0}=u-i\beta_{q}. Differentiating the analytic logarithmic phase underlying (12.20) shows ∂xHq⁢(ξ0)=0\partial_{x}H_{q}(\xi_{0})=0 by the saddle equation z⁢(ξ−1)3=ξ2⁢(ξ−3)z(\xi-1)^{3}=\xi^{2}(\xi-3). Along the lower side,

d2d⁢x2⁢Hq⁢(x−i⁢βq)=−6⁢ℜ⁡1(x−i⁢βq)⁢(x−1−i⁢βq)⁢(x−3−i⁢βq)<0(0≤x≤1),\frac{d^{2}}{dx^{2}}H_{q}(x-i\beta_{q})=-6\Re\frac{1}{(x-i\beta_{q})(x-1-i% \beta_{q})(x-3-i\beta_{q})}<0\quad(0\leq x\leq 1),

because the real part of the denominator is x⁢(x−1)⁢(x−3)+βq2⁢(4−3⁢x)>0x(x-1)(x-3)+\beta_{q}^{2}(4-3x)>0. Hence the unique lower-side maximum is ξ0\xi_{0}. On the vertical sides, parameterized downward,

dd⁢y⁢Hq⁢(−i⁢y)=3⁢arctan⁡y−arctan⁡(y/3)>0,\frac{d}{dy}H_{q}(-iy)=3\arctan y-\arctan(y/3)>0,
dd⁢y⁢Hq⁢(1−i⁢y)=π2+2⁢arctan⁡y−arctan⁡(y/2)>0.\frac{d}{dy}H_{q}(1-iy)=\frac{\pi}{2}+2\arctan y-\arctan(y/2)>0.

On the lower halves of the limiting vertical sides, parameterized as ξ=−i⁢y\xi=-iy and ξ=1−i⁢y\xi=1-iy with 0<y≤βq0<y\leq\beta_{q}, the displayed derivatives are strictly positive. On the upper halves use the exact reflection identity Hq⁢(x+i⁢y)=Hq⁢(x−i⁢y)−2⁢π⁢yH_{q}(x+iy)=H_{q}(x-iy)-2\pi y for y>0y>0. Hence neither upper vertical half can exceed its reflected lower half, and the maxima on both lower vertical halves occur at their lower endpoints. The strictly concave lower horizontal phase has its unique maximum at the interior saddle ξ0\xi_{0}, strictly above both endpoints.

The logarithmic potentials defining HqH_{q} are continuous when ξ\xi approaches the real integration intervals because their logarithmic singularities are integrable. They are therefore uniformly continuous on a compact neighborhood of the limiting rectangle. The maxima over the boundaries of the scaled finite rectangles converge to the maximum over the limiting boundary. The original rectangles have perimeter Oq⁢(n)O_{q}(n), while (12.19) contributes only a polynomial factor in nn to the modulus bound. Taking nn-th roots now gives the claimed rate bound.

(12.21) lim supn→∞|Fn±⁢(−1/q)|1/n≤eHq⁢(ξ0).\limsup_{n\to\infty}|F_{n}^{\pm}(-1/q)|^{1/n}\leq e^{H_{q}(\xi_{0})}.

To evaluate this number, choose logarithms continuously from the lower contour. An antiderivative gives the analytic phase

Ψq⁢(ξ)=3⁢(ξ−1)⁢Log⁡(ξ−1)−(ξ−3)⁢Log⁡(ξ−3)−2⁢ξ⁢Log⁡ξ+(−log⁡q+i⁢π)⁢ξ.\Psi_{q}(\xi)=3(\xi-1)\operatorname{Log}(\xi-1)-(\xi-3)\operatorname{Log}(\xi-% 3)-2\xi\operatorname{Log}\xi+(-\log q+i\pi)\xi.

At the lower saddle choose the principal logarithms of ξ0,ξ0−1,ξ0−3\xi_{0},\xi_{0}-1,\xi_{0}-3, whose arguments lie in (−π,0)(-\pi,0) (with the negative-real limiting value approached from below). The algebraic saddle equation implies that Ψq′⁢(ξ0)\Psi_{q}^{\prime}(\xi_{0}) is an integer multiple of 2⁢π⁢i2\pi i. As q→∞q\to\infty, the lower root satisfies ξ0=−i/3⁢q+O⁢(q−1)\xi_{0}=-i/\sqrt{3q}+O(q^{-1}); the three arguments tend respectively to −π/2,−π,−π-\pi/2,-\pi,-\pi. The corresponding imaginary-part combination is zero, so continuity in q>1q>1 forces this integer multiple to vanish identically. Substituting the saddle equation into Ψq\Psi_{q} gives

eHq⁢(ξ0)=|ξ0−3ξ0−1|3.e^{H_{q}(\xi_{0})}=\left|\frac{\xi_{0}-3}{\xi_{0}-1}\right|^{3}.

For y=(ξ−3)/(ξ−1)y=(\xi-3)/(\xi-1) the saddle equation becomes y⁢(y−3)2=4⁢zy(y-3)^{2}=4z. Its real root is y0=−s−2/qy_{0}=-s_{-}^{2}/q, where s−⁢(q)∈(0,2/3)s_{-}(q)\in(0,2/3) is the unique solution of

(12.22) −s−3q−3⁢s−+2=0.-\frac{s_{-}^{3}}{q}-3s_{-}+2=0.

The product of the three roots of y⁢(y−3)2=4⁢zy(y-3)^{2}=4z is 4⁢z=−4/q4z=-4/q. Consequently the squared modulus of either nonreal root is 4/s−24/s_{-}^{2}, and

(12.23) eHq⁢(ξ0)=8s−⁢(q)3.e^{H_{q}(\xi_{0})}=\frac{8}{s_{-}(q)^{3}}.

Finally

Cn⁢(−1/q)=Fn+−Fn−2⁢π⁢i,Bn⁢(−1/q)=Fn++Fn−2+log⁡q⁢Cn⁢(−1/q).C_{n}(-1/q)=\frac{F_{n}^{+}-F_{n}^{-}}{2\pi i},\qquad B_{n}(-1/q)=\frac{F_{n}^% {+}+F_{n}^{-}}{2}+\log q\,C_{n}(-1/q).

Equations (12.21)–(12.23) thus give the same upper exponential rate 8/s−38/s_{-}^{3} for Bn⁢(−1/q)B_{n}(-1/q).

12.5. Integer-form rates and exact cutoffs

The prime number theorem gives log⁡dN=N+o⁢(N)\log d_{N}=N+o(N), while Stirling [13] gives n−1⁢log⁡bn→2⁢log⁡2n^{-1}\log b_{n}\to 2\log 2. With N=2⁢n+1N=2n+1,

(12.24) limn→∞(dN2bn2)1/n=e416.\lim_{n\to\infty}\left(\frac{d_{N}^{2}}{b_{n}^{2}}\right)^{1/n}=\frac{e^{4}}{1% 6}.

No finite global inequality for dNd_{N} is asserted. Combining (12.16), the coefficient bounds, and (12.4) yields

(12.25) lim sup|Ln⁢(q)|1/n\displaystyle\limsup|L_{n}(q)|^{1/n} ≤r+⁢(q):=e416⁢q⁢(3−t⁢(q)1−t⁢(q))3⁢s+⁢(q)6,\displaystyle\leq r_{+}(q):=\frac{e^{4}}{16q}\left(\frac{3-t(q)}{1-t(q)}\right% )^{3}s_{+}(q)^{6}, a=q>1,\displaystyle a=q>1,
(12.26) lim sup|Ln⁢(−q)|1/n\displaystyle\limsup|L_{n}(-q)|^{1/n} ≤r−⁢(q):=e4⁢s−⁢(q)32⁢q,\displaystyle\leq r_{-}(q):=\frac{e^{4}s_{-}(q)^{3}}{2q}, a=−q<−1,\displaystyle a=-q<-1,

where s+s_{+} is the unique root in (0,1)(0,1) of s+3/q−3⁢s++2=0s_{+}^{3}/q-3s_{+}+2=0. The factors are as follows: q2q^{2} from |a|N|a|^{N}, e4/16e^{4}/16 from (12.24), q−3⁢s6q^{-3}s^{6} from the remainder, and the relevant coefficient growth rate. Thus no estimate for an uneliminated logarithmic form is being used.

For the positive rate set z=1/qz=1/q. Implicit differentiation of the two root equations gives

d⁢log⁡r+d⁢log⁡z=1+t+2⁢z⁢s+21−z⁢s+2>0,\frac{d\log r_{+}}{d\log z}=1+t+\frac{2zs_{+}^{2}}{1-zs_{+}^{2}}>0,

so r+⁢(q)r_{+}(q) decreases with qq. On the negative side, q=s−3/(2−3⁢s−)q=s_{-}^{3}/(2-3s_{-}) is increasing in s−s_{-} and r−⁢(q)=e4⁢(2−3⁢s−)/2r_{-}(q)=e^{4}(2-3s_{-})/2 is decreasing. It remains to check four rational endpoints. The Taylor sum for e4e^{4} through degree 16 and a geometric tail bound give

6972316451127702575<e4<3771393642676907548375.\frac{6972316451}{127702575}<e^{4}<\frac{377139364267}{6907548375}.

Opposite signs of the defining cubics at the following rational endpoints isolate the roots. The derivatives are −3⁢(1−t)2−q⁢(6⁢t−3⁢t2)<0-3(1-t)^{2}-q(6t-3t^{2})<0 for t⁢(q)t(q), 3⁢s2/q−3<03s^{2}/q-3<0 for s+⁢(q)s_{+}(q), and −3⁢s2/q−3<0-3s^{2}/q-3<0 for s−⁢(q)s_{-}(q):

t⁢(11)(14179/100000,14180/100000)s+⁢(11)(67602/100000,67604/100000)t⁢(12)(13681/100000,13683/100000)s+⁢(12)(67521/100000,67523/100000)s−⁢(7)(65338/100000,65339/100000)s−⁢(8)(65496/100000,65497/100000)\begin{array}[]{c|c}t(11)&(14179/100000,14180/100000)\\ s_{+}(11)&(67602/100000,67604/100000)\\ t(12)&(13681/100000,13683/100000)\\ s_{+}(12)&(67521/100000,67523/100000)\\ s_{-}(7)&(65338/100000,65339/100000)\\ s_{-}(8)&(65496/100000,65497/100000)\end{array}

Exact rational interval substitution gives

r+⁢(11)(10937/10000,10941/10000)r+⁢(12)(9834/10000,9837/10000)r−⁢(7)(10877/10000,10879/10000)r−⁢(8)(9587/10000,9589/10000)\begin{array}[]{c|c}r_{+}(11)&(10937/10000,10941/10000)\\ r_{+}(12)&(9834/10000,9837/10000)\\ r_{-}(7)&(10877/10000,10879/10000)\\ r_{-}(8)&(9587/10000,9589/10000)\end{array}

and hence r+⁢(12)<1r_{+}(12)<1 and r−⁢(8)<1r_{-}(8)<1. Monotonicity proves r+⁢(q)<1r_{+}(q)<1 for every integer q≥12q\geq 12 and r−⁢(q)<1r_{-}(q)<1 for every integer q≥8q\geq 8.

12.6. All-degree nonvanishing and conclusion

It remains to show that the constructed integer forms do not vanish eventually. Let Um=(3⁢m+1)!/(m!)3U_{m}=(3m+1)!/(m!)^{3}, Kn=((2⁢n+1)!)3/((3⁢n+2)!)2K_{n}=((2n+1)!)^{3}/((3n+2)!)^{2}, and hm=3⁢Hm−H3⁢m+1h_{m}=3H_{m}-H_{3m+1}. Direct extraction from (12.3) gives

Φn⁢(3⁢n+2)=Kn,Φn⁢(3⁢n+3)Kn=8⁢(n+1)9.\Phi_{n}(3n+2)=K_{n},\qquad\frac{\Phi_{n}(3n+3)}{K_{n}}=\frac{8(n+1)}{9}.

For m≥0m\geq 0, put Mm=Bm⁢Cm+1−Cm⁢Bm+1M_{m}=B_{m}C_{m+1}-C_{m}B_{m+1}; in particular M0=B0⁢C1−C0⁢B1M_{0}=B_{0}C_{1}-C_{0}B_{1} is defined by the displayed residue polynomials. For m≥1m\geq 1, put rm=m3/(3⁢m+1)r_{m}=m^{3}/(3m+1) and cm=2+3/m−1/(3⁢m+1)c_{m}=2+3/m-1/(3m+1). The lower endpoint residues give

um,0=−Um,um,1=rm⁢um,0,vm,0=hm⁢um,0,vm,1=rm⁢(hm−cm)⁢um,0.u_{m,0}=-U_{m},\quad u_{m,1}=r_{m}u_{m,0},\quad v_{m,0}=h_{m}u_{m,0},\quad v_{% m,1}=r_{m}(h_{m}-c_{m})u_{m,0}.

Expanding Bm⁢Cm+1−Cm⁢Bm+1B_{m}C_{m+1}-C_{m}B_{m+1} at degrees zero and one gives

Mm⁢(0)=−Um⁢Um+1⁢δm,M_{m}(0)=-U_{m}U_{m+1}\delta_{m},
[z]⁢Mm=Um⁢Um+1⁢{−δm⁢(rm+rm+1)+rm+1⁢cm+1−rm⁢cm},[z]M_{m}=U_{m}U_{m+1}\{-\delta_{m}(r_{m}+r_{m+1})+r_{m+1}c_{m+1}-r_{m}c_{m}\},

The three-form determinant

Δn⁢(z)=det[AnBnCnAn+1Bn+1Cn+1An+2Bn+2Cn+2]\Delta_{n}(z)=\det\begin{bmatrix}A_{n}&B_{n}&C_{n}\\ A_{n+1}&B_{n+1}&C_{n+1}\\ A_{n+2}&B_{n+2}&C_{n+2}\end{bmatrix}

has degree at most 3⁢n+33n+3. Replacing its first column by the corresponding RR-column and using (12.3) shows its order is at least 3⁢n+23n+2. Expanding along that column gives

Δn=Rn⁢Mn+1−Rn+1⁢(Bn⁢Cn+2−Cn⁢Bn+2)+Rn+2⁢Mn.\Delta_{n}=R_{n}M_{n+1}-R_{n+1}(B_{n}C_{n+2}-C_{n}B_{n+2})+R_{n+2}M_{n}.

The last two terms start at degree 3⁢n+53n+5. Also

Rn⁢(z)=Kn⁢z3⁢n+2⁢(1+8⁢(n+1)9⁢z+O⁢(z2)).R_{n}(z)=K_{n}z^{3n+2}\left(1+\frac{8(n+1)}{9}z+O(z^{2})\right).

It follows that

[z3⁢n+2]⁢Δn=Kn⁢Mn+1⁢(0),[z3⁢n+3]⁢Δn[z3⁢n+2]⁢Δn=[z]⁢Mn+1Mn+1⁢(0)+8⁢(n+1)9.[z^{3n+2}]\Delta_{n}=K_{n}M_{n+1}(0),\qquad\frac{[z^{3n+3}]\Delta_{n}}{[z^{3n+% 2}]\Delta_{n}}=\frac{[z]M_{n+1}}{M_{n+1}(0)}+\frac{8(n+1)}{9}.

Substitution of the displayed coefficients gives the ratio −θn-\theta_{n}, with

θn=−δn+1⁢(rn+1+rn+2)+rn+2⁢cn+2−rn+1⁢cn+1δn+1−8⁢(n+1)9.\theta_{n}=\frac{-\delta_{n+1}(r_{n+1}+r_{n+2})+r_{n+2}c_{n+2}-r_{n+1}c_{n+1}}% {\delta_{n+1}}-\frac{8(n+1)}{9}.

Substituting rm,cm,δmr_{m},c_{m},\delta_{m} and clearing denominators gives

(12.27) θn=1728⁢n4+11520⁢n3+28140⁢n2+29965⁢n+1177018⁢(3⁢n+4)2⁢(27⁢n2+108⁢n+104).\theta_{n}=\frac{1728n^{4}+11520n^{3}+28140n^{2}+29965n+11770}{18(3n+4)^{2}(27% n^{2}+108n+104)}.

Therefore

(12.28) Δn⁢(z)=−Kn⁢Un+1⁢Un+2⁢δn+1⁢z3⁢n+2⁢(1−θn⁢z),\Delta_{n}(z)=-K_{n}U_{n+1}U_{n+2}\delta_{n+1}z^{3n+2}(1-\theta_{n}z),

The numerator is positive for n≥0n\geq 0; denominator minus numerator is

2646⁢n4+17640⁢n3+43140⁢n2+46067⁢n+18182>0.2646n^{4}+17640n^{3}+43140n^{2}+46067n+18182>0.

Also δn+1>0\delta_{n+1}>0. Therefore Δn⁢(z)≠0\Delta_{n}(z)\neq 0 for every real 0<|z|<10<|z|<1.

For such zz, the beta integral (12.15) gives Rm⁢(z)≠0R_{m}(z)\neq 0. If both En⁢(z)E_{n}(z) and En+1⁢(z)E_{n+1}(z) vanished, the two adjacent minors of the columns A+Li2⁡(z)⁢CA+\operatorname{Li}_{2}(z)C and BB would vanish. Since Rn⁢(z)R_{n}(z) and Rn+1⁢(z)R_{n+1}(z) are nonzero, this makes the three columns in Δn⁢(z)\Delta_{n}(z) linearly dependent (the conclusion also holds when one of the corresponding BB entries is zero, by using the other adjacent equation). Hence Δn⁢(z)=0\Delta_{n}(z)=0, contradicting (12.28). Thus no two consecutive En⁢(z)E_{n}(z) vanish.

Suppose now that Li2⁡(1/a)=r/s\operatorname{Li}_{2}(1/a)=r/s were rational, in lowest terms. By (12.14), s⁢Ln⁢(a)sL_{n}(a) is an integer for every nn. The strict rate bounds imply Ln⁢(a)→0L_{n}(a)\to 0, so s⁢Ln⁢(a)=0sL_{n}(a)=0 for all sufficiently large nn. This contradicts the fact that no two consecutive En⁢(1/a)E_{n}(1/a), and hence no two consecutive Ln⁢(a)L_{n}(a), vanish. This proves Theorem 12.1.

13. Assembly of the proof

The positive construction supplies the criterion for 2≤n≤112\leq n\leq 11, the signed construction supplies it for −7≤n≤−2-7\leq n\leq-2, and the Hermite–Padé construction supplies it for n≥12n\geq 12 and n≤−8n\leq-8. Together with the two classical evaluations at n=±1n=\pm 1, these ranges prove Theorem 2.1.

Use of AI tools

The author devised the method. Codex (OpenAI, GPT-5.6 Sol) assisted with mathematical exploration and implementation. Claude Code (Anthropic, Claude Opus 5.5) assisted with review of the implementation, parameters, and printed data; that review is not a proof of the mathematical claims. The directed numerical bounds are computer-assisted: they were obtained with outward-rounded interval arithmetic as specified in Appendix C. The author is responsible for the mathematical statements and their interpretation.

Appendix B Exact signed reference data

Every entry below is an ordinary signed base-ten integer. For real chains, divide each length integer by 10810^{8} and each mass increment by 10810^{8}. A single listed correction (j,r)(j,r) adds r/(5⋅1013)r/(5\cdot 10^{13}) to length jj; j=0j=0 means no correction. Start each chain at its printed endpoint (units 1/(5⋅1013)1/(5\cdot 10^{13})), then accumulate lengths from left to right. Start each mass at zero and accumulate Δ⁢mi\Delta m_{i}. For Poisson rows divide all increments by 10810^{8}, accumulate coordinates and masses from zero, then append the reversed conjugates of all but the final (real) prefix row. Entries are read left to right and then top to bottom. These conventions, together with the displayed masses and supports, determine every reference measure uniquely.

Appendix C Exact certificate algorithm

All numerical bounds in this appendix are computer-assisted. The code and logs supplied as ancillary files use outward-rounded directed interval arithmetic; the rules below specify the calculation independently of those files. All inputs are the printed tables. Terminating decimals and fractions are parsed as exact rationals; a missing or duplicate field, invalid mass, failed strict inequality, or unresolved cell is fatal. No unprinted numerical data are part of the argument.

Shared quadratic duality.

Let Q⁢(𝝁)=B⁢(𝝁,𝝁)Q(\boldsymbol{\mu})=B(\boldsymbol{\mu},\boldsymbol{\mu}) be a quadratic form with symmetric polarization BB, and let ℰ⁢(𝝁)=C+Q⁢(𝝁)+L⁢(𝝁)\mathcal{E}(\boldsymbol{\mu})=C+Q(\boldsymbol{\mu})+L(\boldsymbol{\mu}), where LL is linear. For a fixed reference 𝝂\boldsymbol{\nu}, let FiνF_{i}^{\nu} be the component potentials representing L⁢(𝝁)+2⁢B⁢(𝝂,𝝁)L(\boldsymbol{\mu})+2B(\boldsymbol{\nu},\boldsymbol{\mu}), and assume μi\mu_{i} and νi\nu_{i} have the same prescribed mass in each component. With 𝝈=𝝁−𝝂\boldsymbol{\sigma}=\boldsymbol{\mu}-\boldsymbol{\nu}, polarization gives the exact identity

ℰ⁢(𝝁)=C−Q⁢(𝝂)+∑i∫Fiν⁢𝑑μi+Q⁢(𝝈).\mathcal{E}(\boldsymbol{\mu})=C-Q(\boldsymbol{\nu})+\sum_{i}\int F_{i}^{\nu}\,% d\mu_{i}+Q(\boldsymbol{\sigma}).

Thus a nonnegative (respectively nonpositive) zero-mass remainder gives the lower (respectively upper) dual bound. The P0 and V proofs below differ only in the sign proof for this remainder and in their explicit transfer constants.

P0 endpoint measures.

Divide each printed integer mass by its table denominator. On every pinned or frequency interval [bi−1,bi][b_{i-1},b_{i}], use the uniform measure of that mass. The contour has N=64N=64 nodes

θj=π⁢(2⁢j+1)/64,c63−j=cj,F48⁢(θ)=149⁢|∑k=048ei⁢k⁢θ|2.\theta_{j}=\pi(2j+1)/64,\quad c_{63-j}=c_{j},\qquad F_{48}(\theta)=\frac{1}{49% }\left|\sum_{k=0}^{48}e^{ik\theta}\right|^{2}.

The nine (respectively eight) printed pair masses at q=2q=2 (respectively q=11q=11) occupy the first nodes; zero-fill the rest of the first half, then reflect. The contour density is (2⁢π)−1⁢∑jcj⁢F48⁢(θ−θj)(2\pi)^{-1}\sum_{j}c_{j}F_{48}(\theta-\theta_{j}). The algorithm verifies exact total masses, nonnegative weights, interval density bounds, and the printed ellipse (ξ,A,B)(\xi,A,B). For an interval row use the primitive H⁢(u)=u⁢(log⁡u−1)H(u)=u(\log u-1) with H⁢(0)=0H(0)=0; for the contour use the finite Fourier/Joukowski formulas below. Put

c=A+B2,d=A−B2,ρ=dc,z⁢(u)=ξ+c⁢ei⁢u+d⁢e−i⁢u,c=\frac{A+B}{2},\qquad d=\frac{A-B}{2},\qquad\rho=\frac{d}{c},\qquad z(u)=\xi+% ce^{iu}+de^{-iu},

and

mn=49−n49⁢∑j=063cj⁢cos⁡(n⁢θj),γn=(1+ρn)⁢mnn(1≤n≤48).m_{n}=\frac{49-n}{49}\sum_{j=0}^{63}c_{j}\cos(n\theta_{j}),\qquad\gamma_{n}=% \frac{(1+\rho^{n})m_{n}}{n}\quad(1\leq n\leq 48).

These are exact algebraic numbers in the real subfield generated by eπ⁢i/64e^{\pi i/64} and are enclosed by directed algebraic (or Arb) intervals; they are not assumed to be rational. On the contour,

Uν⁢(z⁢(u))=M⁢log⁡c−∑n=148γn⁢cos⁡(n⁢u).U_{\nu}(z(u))=M\log c-\sum_{n=1}^{48}\gamma_{n}\cos(nu).

For a real point inside the ellipse set w=(t−ξ)/cw=(t-\xi)/c and P0⁢(w)=2,P1⁢(w)=w,Pn⁢(w)=w⁢Pn−1⁢(w)−ρ⁢Pn−2⁢(w)P_{0}(w)=2,\ P_{1}(w)=w,\ P_{n}(w)=wP_{n-1}(w)-\rho P_{n-2}(w). Then

Uν⁢(t)=M⁢log⁡c−∑n=148mnn⁢Pn⁢(w).U_{\nu}(t)=M\log c-\sum_{n=1}^{48}\frac{m_{n}}{n}P_{n}(w).

For a real point −t-t on the negative axis to the left of the ellipse, let

u=t+ξ,Δt=u2−4⁢c⁢d,st=−2⁢cu+Δt,u=t+\xi,\qquad\Delta_{t}=\sqrt{u^{2}-4cd},\qquad s_{t}=-\frac{2c}{u+\Delta_{t}},

where the positive real square root is chosen and |st|<1|s_{t}|<1. The exterior formula is

Uν⁢(−t)=M⁢log⁡u+Δt2−∑n=148γn⁢stn.U_{\nu}(-t)=M\log\frac{u+\Delta_{t}}{2}-\sum_{n=1}^{48}\gamma_{n}s_{t}^{n}.

The same formulas are used for interval boxes, with square roots and logarithms evaluated by outward rounding. For a complex contour point and a real interval, use

ℐ⁢(z;a,b)=ℜ⁡{ℒ⁢(z−a)−ℒ⁢(z−b)},ℒ⁢(y)=y⁢(log⁡y−1),\mathcal{I}(z;a,b)=\Re\{\mathcal{L}(z-a)-\mathcal{L}(z-b)\},\qquad\mathcal{L}(% y)=y(\log y-1),

with the logarithm continued from the upper half-plane; the lower half is obtained by conjugation. On a real crossing, split at the crossing and use H⁢(u)=u⁢(log⁡|u|−1)H(u)=u(\log|u|-1), H⁢(0)=0H(0)=0. Thus all mixed contour–interval potentials, their primitives, and the contour self-energy

I⁢(ν,ν)=M2⁢log⁡c−∑n=148(1+ρn)⁢mn2nI(\nu,\nu)=M^{2}\log c-\sum_{n=1}^{48}\frac{(1+\rho^{n})m_{n}^{2}}{n}

are finite expressions in the printed masses and geometry. No unprinted recurrence or rationality assertion is used.

V reference tables.

The V data in Section B are printed as signed decimal integers in ordinary tables. In each real chain, the header gives the initial endpoint in units of 1/(5⋅1013)1/(5\cdot 10^{13}); each displayed length is in units of 10−810^{-8}, except for the single residual recorded by (j,r)(j,r) in the header, which adds r/(5⋅1013)r/(5\cdot 10^{13}) to length jj (the pair (0,0)(0,0) means no correction). Mass increments are in units of 10−810^{-8}. Starting from zero mass, accumulate each pair left to right and top to bottom. In each Poisson prefix, all three columns are successive increments of the real coordinate, imaginary coordinate, and mass, in units of 10−810^{-8}. The table header gives the prefix and full row counts; these must agree with Table 10.1. Complete the Poisson list by adjoining the reversed conjugates of all prefix rows except its final real row. The verification checks every count, increment, support, total mass, and conjugate pair. Real rows are uniform. A Poisson row is harmonic measure on |z|=r=3/5|z|=r=3/5, with density w⁢(r2−|c|2)/(2⁢π⁢|r⁢ei⁢θ−c|2)w(r^{2}-|c|^{2})/(2\pi|re^{i\theta}-c|^{2}) and potential w⁢log⁡|r2−z⁢c¯|−w⁢log⁡rw\log|r^{2}-z\bar{c}|-w\log r inside, w⁢log⁡|z−c|w\log|z-c| outside, and their common boundary value. It requires the exact strict test |c|2<r2|c|^{2}<r^{2}.

Directed interval evaluation.

For a real interval row the potential is evaluated by HH; pair integrals use G⁢(u)=12⁢u2⁢log⁡|u|−34⁢u2G(u)=\frac{1}{2}u^{2}\log|u|-\frac{3}{4}u^{2}, G⁢(0)=0G(0)=0. The V denominator field uses

∫ablog⁡(q+x⁢t)⁢𝑑t=(q+x⁢b)⁢(log⁡(q+x⁢b)−1)−(q+x⁢a)⁢(log⁡(q+x⁢a)−1)x,\int_{a}^{b}\log(q+xt)\,dt=\frac{(q+xb)(\log(q+xb)-1)-(q+xa)(\log(q+xa)-1)}{x},

with value (b−a)⁢log⁡q(b-a)\log q at x=0x=0. Its energy series for log⁡(q+x⁢v)\log(q+xv) ends at degree 420420; the absolute tail is at most 2⁢Mx⁢Mv/(421⁢q421)2M_{x}M_{v}/(421q^{421}), since 0≤x⁢v/q≤1/20\leq xv/q\leq 1/2.

The V supports cover the entire admissible set. The lower circle follows by conjugation. The two real endpoint boxes are discharged by the displayed endpoint inequalities rather than by evaluating log⁡0\log 0. Nonfinite balls, unvisited endpoints, or unresolved cells are rejected. Finally recompute QqQ_{q} and require the directed lower endpoint of

Qq,−−32⁢log⁡q−Kx,q−54⁢Kv,q−Kz,qQ_{q,-}-\frac{3}{2}\log q-K_{x,q}-\frac{5}{4}K_{v,q}-K_{z,q}

to exceed the printed rational αq\alpha_{q} for every q=2,…,7q=2,\ldots,7.

All quantities needed for these evaluations are printed in the preceding tables or defined by the displayed formulas. The leaf intervals generated by the bisection rule are auxiliary computation, not additional data.
