The pith
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
The reading
What carries the argument
The load-bearing machinery is the 1991 asymptotic formula (3.2) for Titchmarsh's sum over the Gram sequence $(t_\nu)$, the points where $\vartheta(t_\nu)=\pi\nu$: $$\sum_{T\le t_\nu\le 2T} |\zeta(\tfrac12+it_\nu)|^2|\zeta(\tfrac12+it_{\nu+1})|^2 = \frac{3}{4\$pi^{5}$}T\$ln^{5}$ T\,(1+O(1/\ln T)).$$ This is combined with quotient formulas, such as (3.1), that express $\ln T$ through integrals of $|\zeta(\tfrac12+it)|^2$ and $|\zeta(\sigma+it)|^2$ over reverse-iteration intervals of what the paper calls Jacob's ladders, a family of reverse iterations $\varphi_1^{-r}(T)=r/T$ that partition the Hardy-Littlewood integral into asymptotically equal parts. The substitution $T=\frac{4\pi^5}{3\zeta^5(2\sigma)}x\tau$ makes the cross-bred product of five integrals and the Gram sum equal $x$, converting the asymptotic formula into an exact limit identity.
What would settle it
An independent proof or numerical computation of $\sum_{T\le t_\nu\le 2T} |\zeta(\tfrac12+it_\nu)|^2|\zeta(\tfrac12+it_{\nu+1})|^2$ for large $T$ that disagrees with $(3/(4\pi^5))T\ln^5 T$ would invalidate the chain; likewise, a direct evaluation of the limit in (3.6) for any fixed $x>0$ that returns a value different from $x$ would refute the claimed identity.
Extended reading notes
Core claim
The central discovery is Theorem 1: for every fixed $\sigma\ge 1/2+\epsilon$, the zeta-condition (3.8) -- that the displayed limit built from $|\zeta(\sigma+it)|^2$, $|\zeta(\tfrac12+it)|^2$, and the Titchmarsh sum over Gram points is not equal to $1$ -- is proposed as a new equivalent of the Fermat-Wiles theorem. The reason is Lemma 2, identity (3.7): the same limit is forced, by the asymptotic formula (3.2) and the substitution $T=\frac{4\pi^5}{3\zeta^5(2\sigma)}\frac{x^n+y^n}{z^n}\tau$, to equal exactly $(x^n+y^n)/z^n$. Hence the inequality in (3.8) says that $x^n+y^n\neq z^n$ for positive integers $x,y,z$ and $n\ge 3$. Theorems 3 and 4 repeat the construction with Selberg's $S_1(t)$ integrals and with the fourth-power Gram sum, yielding two further equivalents.
Load-bearing premise
The whole chain rests on the 1991 asymptotic formula for the Titchmarsh sum over Gram points, which the paper cites but does not prove; if its leading term were not $(3/(4\pi^5))T\ln^5 T$, the constructed limits would not equal $x$ and the equivalences would collapse.
Editorial extensions
If this is right
- If Theorem 1 is correct, Fermat's Last Theorem becomes the assertion that the explicit limit in (3.8) is never equal to 1 for any Fermat rational.
- Theorem 3 yields a second equivalent in which the integral of $|S_1(t)|^{2l}$ replaces the $\sigma$-integral, for every fixed $l\in\mathbb N$.
- Theorem 4 yields a third equivalent based on the fourth-power Gram sum $\sum |\zeta(\tfrac12+it_\nu)|^4$ rather than on products of neighbouring Gram values.
- The chain (6.1) joins the three new functionals to the author's earlier equivalents, giving a continuum of chains as $x$ ranges over an interval.
Reading between the lines
- Editorial extension: since the limit is forced by construction to equal the Fermat rational itself, these equivalences are exact rewrites of Fermat's Last Theorem rather than new analytic estimates; they do not by themselves offer a route to deciding the inequality.
- Editorial extension: the same device can be applied to any Diophantine condition by substituting the relevant rational expression into $x$; the Fermat case is one instance of a general template.
- Editorial extension: the weak point of the whole chain is the unproved asymptotic formula (3.2), so independently testing or proving that formula is the natural first check of the claimed equivalences.
Editorial analysis
A structured set of objections, weighed in public.
Referee Report
Summary. This paper (arXiv:2506.01706) claims to produce three new 'zeta-equivalents' of the Fermat-Wiles theorem. The author starts from an asymptotic formula for the Titchmarsh sum over Gram points, combined with a quotient formula for integrals of |zeta(1/2+it)|^2 and |zeta(sigma+it)|^2, to obtain a functional identity F(x)=x (Lemma 1). Substituting x=(x^n+y^n)/z^n yields Lemma 2, from which Theorem 1 asserts that a certain limit expression being different from 1 is a zeta-equivalent of FLT. Sections 4 and 5 produce analogous statements using Selberg's formula and a fourth-moment Gram sum. Section 6 continues a chain of formal equivalences from earlier preprints.
Significance. At most the paper shows that, assuming the quoted asymptotics, a particular zeta-integral/Gram-sum limit is algebraically equal to a prescribed positive number x. Since the result is constructed by substitution, the claimed equivalence to FLT is tautological: the condition 'limit != 1' is exactly '(x^n+y^n)/z^n != 1'. Thus the paper does not present a substantive new reformulation of FLT. The computations are explicit and the logic from the quoted formulas to the final identities is transparent, but the central intellectual claim that these are new zeta-equivalents is not supported. The paper also relies on its own cited asymptotic formulas without proof or independent verification.
major comments (3)
- [Section 3.2, Theorem 1; Eq. (3.7)] Lemma 2 (Eq. (3.7)) proves that the limiting expression in Theorem 1 equals (x^n+y^n)/z^n identically. Consequently, the condition (3.8) that this limit is not equal to 1 is, by the same equality, exactly the inequality x^n+y^n != z^n. No property of the zeta function beyond the algebraic manipulation of the quoted asymptotic formula is used. The equivalence is therefore a tautological restatement of the Fermat inequality in the language of zeta-integrals and Gram sums. The same criticism applies verbatim to Theorem 3 (Eq. (4.10)) and Theorem 4 (Eq. (5.6)).
- [Section 3.1, Eq. (3.2) / Eq. (1.8)] The functional identity F(x)=x, and hence all three theorems, depends on the exact leading term 3/(4 pi^5) T ln^5 T in the Titchmarsh sum (3.2). This formula is cited from the author's own 1991 paper [4] and its proof is not reproduced or independently verified in the manuscript; the 1980 proof of Titchmarsh's hypothesis [3] is also cited without proof. Since the substitution (3.5) is calibrated to this precise constant and power of logarithm, the claimed equivalence would fail if the true asymptotic had a different constant or exponent. A load-bearing input of this kind cannot be left as a reference to the author's previous work.
- [Section 2.1, Eqs. (2.1)-(2.2)] The definition of reverse iterations of Jacob's ladders is internally inconsistent in the displayed form: if phi_1^{-r}(T)=r/T as written, then the assertion T ~ ^1T in (2.5) is impossible for T tending to infinity, and phi_1(r/T)=(r-1)/T cannot hold for r>1. This makes the notation [A]_1 used in all subsequent integrals ambiguous, and the reader cannot verify the exact domain of integration in Lemmas 1-4 and Theorems 1, 3, and 4.
minor comments (6)
- [Section 3.2] 'wee obtain' is a typo for 'we obtain'.
- [Eqs. (3.6), (3.8), (4.9), (4.10), (5.5)] The notation [A]_1 appearing in the integral limits is not defined in the paper; the author should clarify whether it denotes the reverse iteration ^1T and define it consistently with Section 2.
- [Eqs. (1.10), (1.12), (3.6), (3.8)] The integral limits are typeset in a way that is very hard to parse; the common substitution factor should be defined once and displayed separately to improve readability.
- [References] The bibliography entry [16] spells the author's name 'Titschmarsh' in the reference list; it should be 'Titchmarsh'.
- [Remarks 1, 5, and Section 6.2] The philosophical digressions about 'Pythagorean philosophy' and the 'Friedmann-Hubble expanding Universe', as well as the Hardy quotation, do not contribute to the mathematical content and are out of place in a research paper.
- [References [5]-[13]] Several of the cited preprints are the author's own works that are not readily available in standard databases; the manuscript should state which specific statements from these preprints are being used.
Circularity Check
Theorem 1's ζ-condition is the Fermat inequality by construction: Lemma 2 fixes the limit to equal (x^n+y^n)/z^n, so '≠1' is just x^n+y^n≠z^n.
-
self definitional
[Section 3.2, Lemma 2 (eq. 3.7) and Theorem 1 (eq. 3.8)]
"Lemma 2. ... = xn + yn / zn ... Consequently, we have the following result Theorem 1. The ζ-condition ... != 1 ... represents the next ζ-equivalent of the Fermat-Wiles theorem."
Lemma 2 is obtained by substituting T = (4π^5/(3ζ^5(2σ)))·((x^n+y^n)/z^n)τ into eq. (3.4), so the leading T ln^5 T term cancels and the displayed limit equals (x^n+y^n)/z^n identically. Therefore the 'ζ-condition' in Theorem 1, namely that the same limit is not equal to 1, is exactly (x^n+y^n)/z^n ≠ 1, i.e., x^n+y^n ≠ z^n. The claimed equivalence with Fermat's Last Theorem is built in by the choice of x, not derived from the zeta-function structure; the analytic expression is forced to equal the Fermat rational by construction.
-
self citation load bearing
[Section 1.2(C) and Section 3.1(B), eqs. (1.8) and (3.2)]
"Next, in 1991, we have derived the following asymptotic formula (1.8) ... = 3/4π^5 T ln^5 T + O(T ln^4 T) (see [4], (2.4), (2.6) and (2.10))."
Every lemma and theorem in Sections 3–5 is obtained by algebraic rearrangement of this asymptotic formula after substituting T = C·xτ, with the Fermat rational then inserted for x. The formula is quoted from the author's own 1991 paper [4] and is not proved or independently verified in the present paper. Thus the genuinely analytic content of all three 'new zeta-equivalents' resides entirely in a load-bearing self-citation, while the connection to Fermat's Last Theorem is produced by the substitution rather than by any new zeta-function argument.

renaming known result
[Sections 4.2–5.1, Theorems 3 and 4 (eqs. (4.10) and (5.6))]
"Finally, we obtain from (4.9), exactly as we did it in (3.6) – (3.8), the following result. Theorem 3. The ζ-condition ... != 1 ... represents new ζ-equivalent of the Fermat-Wiles theorem."
Theorems 3 and 4 are produced by literally repeating the same substitution with different constants and integrands: the limit is again made to equal (x^n+y^n)/z^n, so the '≠ 1' conditions are just the Fermat inequality x^n+y^n ≠ z^n rewritten with S1-integrals or fourth powers of |ζ(1/2+itν)|. These are not independent equivalents; they are the same tautological restatement relabeled through the self-cited asymptotic formulae and Selberg's formula.
full rationale
The paper's central derivation is not a substantive new reformulation of Fermat's Last Theorem, because the claimed ζ-condition is manufactured to equal the Fermat rational. Lemma 1 shows that the chosen cross-bred expression is identically x after the substitution (3.5); Lemma 2 then specializes x to (x^n+y^n)/z^n, making Theorem 1's condition 'limit ≠ 1' literally equivalent to x^n+y^n ≠ z^n. The same construction is repeated in Theorems 3 and 4. If the asymptotic formula (3.2)/(1.8), quoted from the author's 1991 paper [4], is accepted, the identities are correct as algebraic consequences, but the 'new zeta-equivalents' carry no additional number-theoretic content beyond substituting the Fermat rational into that self-cited formula. Hence the central claim reduces by definition to its own input: the statement to be proved is embedded in the value chosen for x. Score 9 rather than 10 only because the underlying asymptotic formula, if independently established, would be a genuine analytic result; but the Fermat equivalence itself is tautological.

abstract
In connection of our proof (1980) of the Titchmarsh's hypothesis (1934), we have obtained two asymptotic formulae (1991). In this paper we obtain three new $\zeta$-equivalents of the Fermat-Wiles theorem based on the mentioned asymptotic formulae.
