梁经纬 · 上海交通大学Paper2Formalization: Auto-Formalization of Research Papers
In this talk, I will present a paper to formal agentic framework for automated formalization of math research papers in Lean. The framework contains three agents: an ocr agent with LLM supervision, a plan agent based on knowledge-graph, and an automated formalization agent. The proposed agentic framework is tested over 30 papers on optimization theory, producing a Lean library of more than 110,000 lines of codes.

曹一川 · 中国科学院MechMath Agent Team: LLM Driven Agents for Mathematical Research
AI reasoning has become a central focus in contemporary artificial intelligence, largely driven by the success of large language models. However, mathematical research, which is characterized by non-linear derivation paths, rigorous logical requirements, and protracted exploration cycles, poses severe challenges for existing reasoning systems. To overcome these limitations, we present the MechMath Agent Team (MMAT), which is a large language model driven agent designed to serve as a co-pilot throughout the full cycle of mathematical research. We design a tripartite Harness Architecture that decouples system responsibilities into Control, Execution, and Augmentation planes, thereby reconciling rigorous logical control with the agility demanded by open-ended research. Building upon this framework, we instantiate three specialized agents: a Knowledge Base Manager, a Natural Language Prover, and a Formal Language Prover, all operating in a closed loop to produce formally certified mathematical proofs. We evaluate MMAT on open problems in Number Theory, Algebraic Complexity Theory, Differential Algebra, Operator Algebra, and Inequalities. Across a two-month deployment, 11 problems have been solved, demonstrating its capacity to act as a co-pilot throughout the entire research cycle. The contributions are threefold: a general decoupled Harness Architecture for multi-agent mathematical reasoning, its concrete instantiation in the MMAT system, and empirical validation on a diverse suite of open problems.
14:00 – 14:30
关乃粼 · 北京大学Formalization of Hierarchy of Local Rings in Lean4
This talk reports on a formalization project in the Lean4 theorem prover for the hierarchy of local rings in commutative algebra. We develop the theories of depth and Cohen--Macaulay rings, proving the Auslander--Buchsbaum and Ischebeck theorems, and obtain a homological characterization of regular local rings via maximal Cohen--Macaulay modules and a weakened version of the Ferrand--Vasconcelos theorem. We then investigate Gorenstein rings, showing that they are Cohen--Macaulay of type one, and complete intersection rings using the epsilon-one invariant and Koszul complex. A key technical contribution is the construction of Ext maps induced by exact functors, which enables dimension--shifting arguments. The formalization also includes the Koszul complex that benefits from AI-assisted proving for exterior algebra and base-change lemmas. The overall result establishes full formalization of hierarchy of local rings and some related theories.
14:30 – 15:00
徐霄乾 · 昆山杜克大学AI Proofs in PDEs
In this talk, I will discuss recent results on fluid equations done by AI. I will first outline the relationship between the mixing properties of incompressible flows and the diffusion process, including dissipation enhancement. I will then focus on the so-called unmixing phenomenon and on the existence of Batchelor scales for certain flows, both of which are results recently proved using AI.

Ajay Kumar Nair · 印度科学院LeanAide: Extensible Autoformalization by Combinator Code Generation
Autoformalization is the process of automatically translating natural language mathematics into machine-verifiable code. The most successful machine-verifiable formats in this space are theorem provers, among which Lean has found much success as an interactive theorem prover in recent times.

LeanAide is an approach to autoformalization into the Lean theorem prover that offers modularity and extensibility in many aspects such as using AI models of one's choice and adding combinators to suit specific domains. While strong autoformalization agents are emerging, our project stands out as an open-source, extensible system written primarily in Lean, leveraging its wonderful metaprogramming framework. This is achieved by writing various handlers for different kinds of mathematical constructs and composing those handlers to generate the final output. We call this novel approach Combinator Code Generation. LeanAide is architected such that any improvements in rule-based automation (e.g., grind) or large language models will directly improve its autoformalization capabilities.

邱瑞晨 · 中国科学院MechMath: Sorrifier-Driven Formal Decomposition Workflow for Automated Theorem Proving
Recent advances in large language models (LLMs) and LLM-based agents have substantially improved the capabilities of automated theorem proving. However, for problems that require complex mathematical reasoning, current systems rarely succeed on the first try and must repeatedly modify their proof strategies. Existing approaches for handling failed attempts typically either iteratively fix errors within the proof or discard the entire proof and regenerate it from scratch. The former leads to progressively longer contexts, which progressively degrade the model’s ability to attend to the remaining unresolved subproblems, while the latter is inefficient, as it may abandon mostly correct reasoning due to localized errors. To address this dilemma, we propose MechMath, a novel agent system that employs a sorrifier-driven formal decomposition strategy. By leveraging the sorry placeholder in Lean to precisely isolate unresolved subgoals while preserving the surrounding verified proof structure, MechMath extracts each failed subproblem into a clean, self-contained context and resolves it independently. This avoids both the waste of full regeneration and the excessive context length induced by repeated repairs. Experimental results on challenging mathematical competition benchmarks, including IMO 2025, Putnam 2025, miniF2F, and a subset of ProverBench, demonstrate that our agent achieves significant advantages in proving efficiency.

赵雨扬 · 香港中文大学(深圳)Mathlib 类型类层次结构的设计
类型类是 mathlib 中广泛使用的重要机制,它极大地方便了形式化过程中对数学对象的操作。但随着层次结构不断加深、加宽,这套机制在设计与使用中也带来了不少困难。本报告将介绍 mathlib 类型类层次结构的设计、遇到的问题以及相应的应对方法。报告首先介绍类型类的组织方式,继而讨论随着层次结构的增长与复杂化而在实践中显现的种种问题,例如实例的菱形(diamond)与推断性能等,并说明针对这些问题的应对方法。报告最终指出,形式化系统中一个结构应携带哪些数据,往往不取决于数学上的最简或最习惯的表述,而取决于 API 的可维护性与效率。要在系统中方便而高效地做数学,背后需要这样细致的设计权衡。

李鹏 · 清华大学自然语言驱动的数学研究智能体——AIM系统的探索与实践
数学作为科学进步的重要基石,长期支撑着各学科的发展与突破。近年来,人工智能的迅猛发展正在推动科学研究范式发生深刻变革,也为数学研究带来了新的机遇与挑战。当AI遇见数学,尤其是当自然语言成为数学研究智能体理解问题、组织推理与协同探索的重要界面时,将会产生怎样的化学反应?本报告将围绕“自然语言驱动的数学研究智能体”这一主题,简要回顾AI在数学研究中的发展脉络与代表性进展,分析AI面向研究级数学问题时所面临的核心挑战。在此基础上,报告将重点介绍本团队研发的AI数学家系统AIM,展示其如何通过自然语言交互与智能体协作机制,辅助数学问题探索、定理形成与可信验证。

李嘉 · Project Numina大模型如何学会数学:从思维链到形式化证明
大语言模型最初通过预测下一个词学习语言,却在过去几年中迅速获得了求解数学问题、生成复杂推理乃至构造形式化证明的能力。这一进展并非单纯来自模型规模的增长,而是由高质量数学数据、思维链监督、过程奖励、强化学习、工具调用和测试时计算等方法共同推动。本报告将回顾大模型数学能力的发展历程:从MATH、Minerva等早期工作,到代码辅助推理、过程奖励模型和大规模合成数据,再到o1、DeepSeek-R1所代表的长程推理与强化学习范式。结合Project Numina的实践,我们将介绍如何通过NuminaMath数据集与开放模型训练数学推理能力,以及如何在Kimina Prover中将证明搜索轨迹转化为结合自然语言推理与Lean代码的统一推理过程,并利用强化学习提升形式化证明能力。最后,报告将讨论数学AI正在经历的关键转变:从解答有标准答案的竞赛题,走向生成可机器验证的证明、形式化已有数学成果,并进一步参与开放问题和前沿数学研究。

沈颖祺 · 香港中文大学(深圳)Formalizing Extended Complex Numbers, Mobius Transformations, and Cross Ratio in Lean 4
The extended complex plane is a fundamental object in complex analysis, hyperbolic geometry, and mathematical physics. Its geometry is governed by Möbius transformations, with the cross ratio serving as a central invariant. We present a formalization of these concepts in the Lean4 theorem prover. The extended complex plane is represented using Mathlib's Option type over C, where the additional element represents the point at infinity. On this foundation, we define Möbius transformations, their action on the extended complex plane, and the cross ratio. We formalize several basic properties of Möbius transformations, including their group structure, and identify them with a projective general linear group. We also prove the uniqueness of a Möbius transformation mapping any three distinct points to any other three distinct points, and the invariance of the cross ratio. All proofs are machine-checked in Lean 4. The complete development comprises approximately 6,000 lines of Lean code, including about 40 definitions and 150 lemmas and theorems. This work provides a verified foundation for future formalizations of conformal geometry, hyperbolic models, modular forms, and applications in mathematical physics.This is a joint work with Fubin Yan.

王浩丞 · 苏黎世联邦理工学院 / 香港科技大学(广州)FormalRx: Rectify and eXamine Semantic Failures in Autoformalization
The veracious semantic alignment in autoformalization is significant for formal mathematical reasoning. However, existing evaluations provide only opaque binary verdicts or scalar scores, offering no interpretable insight into where or why translations fail. This opacity severely limits both human understanding and automated system improvement. To bridge this gap, we introduce FormalRx, a comprehensive diagnostic evaluation framework that transforms autoformalization assessment from black-box judgments into actionable feedback. At its core is SCI Error Taxonomy, a hierarchical classification scheme decomposing autoformalization errors into 28 distinct categories with strict priority ordering. Building on this taxonomy, FormalRx provides four critical diagnostic capabilities: alignment verdicts, error categorization, error localization, and correction. We instantiate the framework with a diagnostic model FormalRx-8B, trained on 56,287 synthetically generated samples with fine-grained diagnostic annotations, and release FormalRx-Test as the first fine-grained diagnostic benchmark. FormalRx-8B achieves F1-scores of 0.88 (verdict) and 0.71 (categorization), along with accuracies of 0.75 (localization) and 0.73 (correction), substantially outperforming both general-purpose LLMs and specialized baselines. By connecting evaluation with actionable insights, FormalRx enables systematic diagnosis and improvement of autoformalization systems.
14:30 – 15:00
刘方辉 · 上海交通大学LeanMarathon: Toward Reliable AI Co-Mathematicians through Long-Horizon Lean Autoformalization(长程数学推理的自动形式化系统)
In this talk, I will discuss LeanMarathon, a multi-agent harness for reliable research-level Lean autoformalization. Its core abstraction is an evolving blueprint: a Lean file that serves simultaneously as formal proof skeleton, natural-language proof graph, and shared system of record. Four contract-scoped agents construct, audit, prove, and repair this blueprint. These agents are coordinated by a two-stage orchestrator that first stabilizes target fidelity through adversarial review and then discharges the proof directed acyclic graph (DAG) from its dynamic leaves upward in parallel CI-gated rounds. We evaluate LeanMarathon on two recent research papers spanning four Erdős problems (#1051, #1196, #164, #1217). Across three autonomous runs, it formalizes all seven target theorems with no sorry, proving 258 lemmas and theorems. These results show that reliable AI co-mathematics requires not only stronger provers, but durable harnesses that preserve target fidelity across long mathematical developments.

杨柳 · 新加坡国立大学Evolutionary Ensemble of Agents (EvE): A self-evolving agent for math proof, algorithm discovery, and beyond
We introduce Evolutionary Ensemble (EvE), a decentralized framework that organizes existing, highly capable coding agents into a live, co-evolving system for math proof, algorithm discovery, and beyond. By maintaining two co-evolving populations, namely downstream task solvers and agent guidance states, the system keeps evolving the agents based on the marginal gains they contribute to the solvers. Without human intervention, EvE was able to solve a mathematical problem in just one day that previously took one PhD student an entire year to complete. We will also show some results of applying EvE to algorithm discovery, control design, and beyond.

EvE is open-source and actively maintained: https://github.com/scaling-group/eve
