MechGeo: Autoformalizing and Proving Euclidean Geometry in Lean 4

Hao Shen, Junyu Guo, Tian Cui et al.

We present MechGeo, a Mathlib native agentic framework that jointly addresses faithful autoformalization and certified proof construction for Euclidean geometry. In this framework, GeoFormalizer represents informal problems in GeoIR, deterministically trans...

Why it matters Useful for the informal-to-formal bottleneck: it is about preserving mathematical intent across the translation boundary.

Open-Source LLM-Driven Formal Verification: A Multi-Agent Pipeline for RTL Repair

Ha Trung Tran

Verification consumes the majority of modern chip design effort, yet the formal verification tools that provide mathematical guarantees of correctness remain expensive and restrictively licensed. While large language models (LLMs) have shown promise for har...

LEAP: Lean Environment-Feedback via Adaptive Pruning for Code RL in GPU Kernel Generation

Tankun Li, Zhi Chen, Yaohua Tang

Post-training large language models (LLMs) via reinforcement learning (RL) has significantly advanced code generation capabilities. To bypass the heavy memory footprint of critic networks, current state-of-the-art frameworks leverage critic-free paradigms l...

Three Graffiti.pc Conjectures on Largest Induced Trees: Proofs of Conjectures 141, 142, and 143

Alper Ferudun

For a finite simple graph $G$, let $t(G)$ be the largest order of an induced tree and let $g(G)$ be the girth. We prove three consecutive conjectures of DeLaViña's Graffiti.pc program. First, writing $\ell(v)$ for the independence number of the subgraph ind...

The $δ$-calculus: from distinction to arithmetic

Jonathan Washburn, Milan Zlatanović

Let $δ$ denote the primitive act of distinction, formally realized as the one-step extension $r \mapsto Sr$ of a finite record. We study the inductively generated $δ$-orbit and its first-order arithmetic presentation $\mathbb{N}_δ$. The corresponding $δ$-ca...

BlueprintRepair: Typed Local Edits for Failed Lean Proof Blueprints

Ruslan Khrulev

LLM-based Lean proving systems increasingly organize a proof as a blueprint: a dependency graph of formal statements. We introduce BlueprintRepair, a repair interface that lets a model change this graph through ten schema-checked local operations. An operat...

The Set of Correlated Equilibrium Payoffs for a Fixed Information Structure Need Not Be Closed

Michael Greinecker, Patrick Lahr, Christoph Schwerdtfeger

Aumann (1974) showed that an atomless public randomization device makes the feasible- and equilibrium-payoff sets of a game with a fixed information structure convex, and asked whether they are closed. We show that, in every case the question leaves open, t...

Optimal Trading of Microstructure Mean Reversion

Lucas Rabechini Amaral

At the scale of seconds the observed mid carries a stationary, mean-reverting error around a latent efficient price. We build an order book whose own flow produces that error and solve for the trading rule that maximises the long-run average profit rate net...

On a conjecture of Han and Xiong for fractional Gaussian binomial coefficients

Ken Ono

Han and Xiong recently extended the Gaussian binomial coefficient $\genfrac{[}{]}{0pt}{}{r+k}{k}_{q}$ to positive rational $r$ and conjectured that its integer trace, the integer-exponent part of the resulting power series, is coefficientwise largest at $r=...

A Proof of the Dittert Conjecture in Dimension 4 via an Agent-Guided Exact Sum-of-Squares Certificate

Jinhui Li, Beibei Xiong, Zhengfeng Yang

The Dittert conjecture states that the Dittert functional on nonnegative $n\times n$ matrices whose entries sum to $n$ is uniquely maximized by the uniform matrix. We prove the conjecture in dimension $4$. More precisely, let $K_4$ be the simplex of nonnega...
