The Quasi-Riemann Hypothesis: A Zero-Free Half-Plane Re(s) > 7/8

OpenAI

There are absolute constants A,C>0 such that, for every odd prime p, the least positive quadratic nonresidue n(p) is at most C(log p)^A; hence n(p)≪δ p^δ for each δ>0.

Sources for this record

What was already known

Vinogradov conjectured the p^δ bound. The 2017 theorem of Bhargava, Ivanyos, Mittal and Saxena gives a polylogarithmic bound under a uniform weak-GRH zero strip, while GRH gives a stronger logarithmic-squared bound. No unconditional uniform strip of the required fixed width had been established.

AI involvement AI-led

OpenAI is credited as author of the manuscript and states that an internal frontier model produced the release’s mathematics. The specific corollary is an AI-authored deduction combining the manuscript’s claimed new zero-free theorem with an earlier human theorem; task-only autonomy is undocumented.

OpenAI is the author and credits its internal frontier model with the mathematics. This corollary is an AI-authored deduction from the manuscript’s asserted 7/8 zero-free theorem and the earlier Bhargava–Ivanyos–Mittal–Saxena result; individual human inputs are not fully disclosed.

Importance Major

If the new zero-free theorem is correct, this corollary establishes Vinogradov’s classical conjecture and a polylogarithmic bound on least quadratic nonresidues.

Limitations

Corollary 1 derives the bound from the same manuscript’s claimed uniform Dirichlet zero-free half-plane Re(s)>7/8 and the earlier Bhargava–Ivanyos–Mittal–Saxena theorem. Its validity therefore depends on that separately curated zero-free theorem. The published Lean scope explicitly excludes the paper’s later applications, including this corollary; no completed check of the corollary itself was found.

Technical verification Reported

The manuscript derives the nonresidue bound from its asserted 7/8 zero-free theorem and Bhargava–Ivanyos–Mittal–Saxena Theorem 6.7. The official Lean scope explicitly excludes later applications, including this corollary; a completed direct check was not identified.

Human understanding Few

No named human explanation of the new zero-free argument underlying this corollary was identified. The deduction through the published conditional theorem is stated plainly, but that alone does not document human understanding of the central new reasoning.
