An improved zero-free half-plane for Hecke L-functions over number fields and Quasi-Riemann Hypothesis

The Quasi-Riemann Hypothesis

“We establish the quasi-Riemann hypothesis by proving that every Dirichlet L-function, including Riemann's zeta function, has no zeros in the half-plane Re s > 11/12. More generally, we prove the same zero-free half-plane for every finite-order Hecke L-function over K = Q(√−3). In particular, this rules out the existence of Landau–Siegel zeros.”

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

“In particular, Theorem 1.1 resolves the quasi-Riemann hypothesis affirmatively: the supremum of the real parts of the nontrivial zeros of ζ, namely its zeros in 0 < ℜs < 1, is at most 7/8. The boundary ℜs = 7/8 is not included, while any exceptional real zero in (7/8, 1) is excluded. The theorem does not establish the Riemann hypothesis or its generalized versions, which place nontrivial zeros on ℜs = 1/2.”

Generic Future Inextendibility with Square-Integrable Connection Near a Fixed Kerr Spacetime

“Strong cosmic censorship asks whether initial data determine a spacetime that cannot be continued beyond its maximal globally hyperbolic development. The regularity allowed for a continuation is part of the question. Kerr’s smooth inner horizon makes this distinction especially important [2]: a continuation can preserve the metric while losing the regularity needed to interpret its connection. Here we prove a local, Baire-category form of this assertion near each fixed rotating subextremal Kerr bridge, at the threshold of locally square-integrable connection coefficients.”

The Euclidean plane is not five-colorable

“We prove that every coloring of the Euclidean plane with five colors has a monochromatic unit-distance pair, with no regularity assumption on the color classes. Consequently, the chromatic number of the plane is either six or seven.”

Unique games conjecture

The Unique Games Theorem

“We prove the Unique Games Conjecture. For every fixed ε, δ ∈ (0, 1/2), we give a deterministic polynomial-time reduction from 3SAT to Unique Games over a fixed finite alphabet, with completeness at least 1 − ε and soundness at most δ.”

Barendregt–Geuvers–Klop conjecture

Computer science · Open

Proof claimed · 06 Oct 2026

Weak and strong normalization in pure type systems

“We prove that every weakly β-normalizing pure type system is strongly β-normalizing. Both properties quantify over all legal expressions in all valid contexts, and reduction acts inside type annotations. No functionality hypothesis is required. This resolves the β-Barendregt–Geuvers–Klop conjecture.”

Navier–Stokes existence and smoothness

Mathematics · Under review

Proof claimed · Revised · 08 Sep 2026

On the Navier–Stokes Millennium Prize Problem

“Our system produced an analytical proof and a Lean formalization that an initially smooth fluid at rest can develop a singularity in a finite time. The fluid has a smooth force applied to it, and its energy remains finite through the entire dynamics, from rest to the formation of the singularity. This resolves the Navier–Stokes Millennium Prize problem by establishing statement “C” (and also “D”) in the official Millennium Prize formulation.”

Twin prime conjecture

Mathematics · Open

Partial result claimed · Revised · 04 Sep 2026

A fixed-profile proof for prime gaps of at most 182

“Her August 2026 mixed-support preprint lowered the more-than-twelve-year-old bound H1 ≤ 246 to H1 ≤ 240; independent concurrent work by OpenAI, using her 2023 estimates, reached H1 ≤ 186, and the Axiom Math team further developed her framework to reach H1 ≤ 212. Building on these developments with additional Type II and Type III inputs and a new fixed profile, this paper proves H1 ≤ 182.”

A new bound for small gaps between primes

“Stadlmann recently proved that infinitely many pairs of distinct primes are apart by at most 240, improving upon the longstanding bound 246 established by Polymath8b. Building on her work, we prove that lim inf_{n→∞} (p_{n+1} − p_n) ≤ 212.”
