The Proportion of Zeta Zeros on the Critical Line

Prior state unknown→proved

An unconditional record, not a resolution: the Riemann hypothesis is untouched, and Anthropic states it does not expect these techniques to lead to a proof of it. The paper is explicit that these are lower bounds only - the remaining third of the zeros are not shown to be off the line, merely not reached by the certificate. What it does settle is a question that was posed. Goldston and Suriajaya had reduced Montgom…

Prime Gaps at Most 186

Prior state unknown→proved

Assuming three explicit input statements, the project proves DHL[40,2]\mathrm{DHL}[40,2]: every admissible 4040-tuple contains at least two primes infinitely often after translation. An explicit admissible 4040-tuple of diameter 186186 then gives lim inf⁡n→∞(pn+1−pn)≤186.\liminf_{n\to\infty}(p_{n+1}-p_n)\le186. The Lean proof of the implication from the three inputs to the final theorem is kernel-checked. Two inputs are Kloosterman-type estimat…

A new bound for small gaps between primes: H1≤212H_1 \le 212

Prior state unknown→proved

H1≤212H_1 \le 212, improving Stadlmann's 240240 of three days earlier and the 246246 of Polymath8b that had stood since 2014. The twin prime conjecture, H1=2H_1 = 2, is untouched. Held the record for hours at most: OpenAI's paper claiming 186186 is dated 30 August, four days before this one, though its Lean development appeared on 2 September.

The C∞C^\infty Carathéodory Conjecture on Umbilic Points

Prior state unknown→disproved

Only the smooth case falls. Hamburger's real-analytic theorem is untouched, and the counterexample is explicitly a C∞C^\infty object, so the conjecture's classical analytic form remains true. The gap between the two is the whole content of the result.

The Ibragimov–Iosifescu conjecture for φ-mixing sequences

Prior state unknown→disproved

Astra constructs a strictly stationary real process Xt=ξt+K(ξt−1,ξt−2,…), X_t=\xi_t+K(\xi_{t-1},\xi_{t-2},\ldots), where the innovations ξt\xi_t are i.i.d. Gaussian variables convolved with a symmetric rare-spike law, and KK is bounded, continuous, and odd. The process is φ\varphi-mixing, centered, square-integrable, and satisfies Var⁡(Sn)→∞. \operatorname{Var}(S_n)\to\infty. Nevertheless there are times nj→∞n_j\to\infty such that…

(ξαn)n≥1(\xi\alpha^n)_{n\ge1} is not uniformly distributed modulo one for Pisot α\alpha and ξ\xi in the Cantor set C(α)C(\alpha)

proved→proved

The problem is open, and the repository says so: what is proved are criteria for it and two instances, not the general case. Every compared statement that concludes Problem 10.61 does so for a quadratic setup - a real root α>1\alpha > 1 of X2−aX−bX^2 - aX - b whose conjugate has modulus below one - and both instances are quadratic. The arbitrary-degree material is conditional ingredients: for the family…

Problem 3 of Dubickas (2006): Is 3∈Z\sqrt{3} \in \mathcal{Z}?

Prior state unknown→proved

Answers Problem 3 and generalizes it: the classification m∈S  ⟺  m=2\sqrt{m} \in \mathcal{S} \iff m = 2 covers every square root, and a further theorem replaces parity by divisibility by any p≥2p \ge 2. Note the scope of the machine-checking, which is narrower than the paper: the author states that the case m=3m = 3 is what is verified in Lean, and the repository flags the thickness computation of section 4.1 and all of sectio…

The Lyons–White conjecture: rate-monotonicity of ℓ2m\ell^{2m} distances for random walks on dihedral groups

Prior state unknown→proved

No such pair exists: for every positive integer mm and every nn, (Dn,2m)(D_n,2m) is rate-monotonic (Theorem A), and more generally so is every inversion extension of a finite abelian group by an involution, a family containing the generalized dihedral, dicyclic and generalized quaternion groups (Theorem B). The picture is completed in the other direction: for every real p≥1p\ge 1 that is not an even integer there is an…

The γ–θ conjecture in eternal domination

Let HH be the Berlekamp–van Lint–Seidel graph on 243243 vertices, the Cayley graph of Z35\mathbb Z_3^5 with strongly regular parameters (243,22,1,2), (243,22,1,2), and let G=H‾G=\overline H. The proof establishes γ(G)=3 \gamma(G)=3 because every pair has a common neighbor in HH, while an HH-triangle gives a dominating triple in GG. It then proves γ∞(G)=3 \gamma^\infty(G)=3 by showing that the family of all dominating triples…

Local limits along squares and prime values of digital functions

Prior state unknown→proved

New theorems, not a formalisation of known results. In base ten the bare existence of a square with any admissible digit sum was recorded in the recreational literature (Murthy–Ashbacher 2005); the theorem here is the quantitative all-base version — roots coprime to b (excluding their trailing-zero trick), exp(c_b√q) representations of controlled size — and that statement is what is machine-checked, with effective b…

Matrix-Tree Obstruction for Half-Collinear Graviton Vertices

Prior state unknown→proved

Answers the obstruction rather than the whole question: it says exactly when the Matrix-Tree Theorem can be applied and classifies the chambers, and gives a compact five-graviton formula outside the decay region. Simplifying the general solution, which is what the source paper left to future work, remains open.
