NanoProof: Open and Efficient Automated Theorem Proving in Lean 4

Matěj Kripner, Milan Straka

We introduce NanoProof, to our knowledge the first factorized execution-guided theorem prover in Lean 4 whose training data, extraction tooling, training pipeline, and weights are all released, making it end-to-end reproducible using open-source resources....

Humanize Olympiad Agents: A Multi-Session Workflow for Olympiad Problem Solving with Solve, Review, Wiki, Verify

Zhengyang Zhang, Jing Xiong, Hongzhou Lin et al.

Large language model (LLM) agents are rapidly improving on long-horizon scientific and olympiad tasks. Recent systems have produced a Lean-formalized resolution of the Navier--Stokes problem and autonomous solutions to four open questions in the Erdős Conje...

Verification with Transfer: Exact Information Frontiers and Their Price in Calls

Hazar Yueksel

A verifier that accepts or rejects whole answers reveals little: under a flat prior over $k$-bit answers, zero error needs $2^k-1$ verifications. The usual remedy is to solve related source tasks, either all first, as a curriculum does, or interleaved with...

LEVER: Adaptive Cost-Aware Proof Search Over AND/OR Graphs

Nihal Jain, Shuangjie Yao, Begum Cicekdag et al.

Mathematicians value proofs for more than correctness: among correct proofs, simplicity, purity and the computational cost of finding them vary widely. Yet LLM-powered theorem provers largely search for any correct proof, and improve its quality only after...

Hierarchical Melnikov Realization: Logarithmic Factor Improvement to Hilbert Number Lower Bounds

Chaoyang Qin, Xiaoming Sun

The second part of Hilbert's 16th problem is one of the most fundamental open problems in the qualitative theory of ordinary differential equations and dynamical systems. A central unresolved question is whether the Hilbert number $H(d)$ is finite for arbit...

A Lean Formalization of the Hamilton--Perelman Proof of Thurston's Geometrization Conjecture

Yuan Liao, Ziyang Qin, Jui-Hui Chung et al.

We formalize the Hamilton--Perelman Ricci-flow proof of Thurston's geometrization conjecture. The public Lean declaration is reproduced in this paper. Its geometric interpretation follows, and verification is recorded in 4.

SqueezeBench: Saturation-Resilient Evaluation of Mathematical Capability

Pablo Manrique, Hai Xia, Stefan Szeider

AI systems are making rapid progress in mathematics, but this progress is hard to measure. Benchmarks of solved problems saturate, and in benchmarks of open problems each problem can be resolved for the first time only once. We present SqueezeBench, a bench...

Exact rational certificates and a Lean formalization of the eleven-variable Vasc inequality

Dakai Guo, Ruichen Qiu, Yichuan Cao et al.

We prove that the cyclic sum $\sum_{i=0}^{10}(x_i-x_{i+1})/(x_{i+1}+x_{i+2})$ is nonnegative for every strictly positive real eleven-tuple, with indices taken modulo eleven. Clearing denominators reduces the problem to a homogeneous polynomial. Subtracting...

Universal Radial Laws for Random Polynomials: Erdős Problem #522 and Non-Universal Fluctuations

Sebastien Kawada

We resolve Erdős Problem #522, posed in 1961, by proving that for random Littlewood polynomials the proportion of zeros in the closed unit disk converges almost surely to $1/2$. More generally, for partial sums of random power series with i.i.d. coefficient...

The rank of $3\times 3$ matrix multiplication over $\mathbb{F}_2$ is 23

Tejasvi Singh Tomar

The rank of the tensor of $3\times 3$ matrix multiplication over the field with two elements is at most $23$ by Laderman's algorithm, and Rudich and Rousseau recently proved that it is at least $22$. We prove that it equals $23$. Hence Laderman's algorithm...

Natural Language to First-Order Logic LLM-based Autoformalization

Large Language Models (LLMs) have renewed interest in autoformalization. Yet, when First-Order Logic (FOL) is considered as the target formalism, the field still lacks a unified task formulation and a systematic survey. This paper addresses this gap: we fir...
