📝 摘要(中文)

大型语言模型(LLMs)在严格验证复杂数学证明方面存在困难。标准的全局评估方法受到“上下文污染”的影响,导致表面上合理的陈述掩盖了微妙的逻辑缺陷,从而引发幻觉或过度怀疑。为了解决这一问题,本文提出了一种严格的逐步验证框架,该框架为每个推导步骤维护详细的上下文,并严格限制所应用定理的来源。通过对来自FirstProof挑战的研究级证明进行评估,系统的消融研究表明,这些推理约束是不可或缺的。我们的研究结果表明,促使代理以谨慎的方式组织验证笔记,可以显著提高其区分严格证明与错误证明的能力,并为未来的自动化证明审查系统奠定理论基础。

📄 摘要(原文)

Large Language Models (LLMs) struggle to rigorously verify complex mathematical proofs. Standard global evaluation approaches suffer from "context poisoning," in which superficially plausible statements mask subtle logical flaws, leading to hallucination or over-skepticism. To address this, we shift from global evaluation to strict step-level verification: our framework maintains detailed context for each deduction step and strictly constrains the sources of applied theorems. We evaluate on a carefully curated adversarial diagnostic suite of research-level proofs drawn from the FirstProof challenge. A systematic ablation study demonstrates that these deductive constraints are indispensable, as unconstrained global prompting consistently fails to localize subtle logical errors. Beyond outperforming global evaluation, our approach fundamentally alters the failure taxonomy. Error analysis reveals that, rather than exhibiting severe logical hallucinations, remaining rejections are primarily instances of "pedantic hyper-rigor" stemming from unstated domain conventions, effectively exposing implicit ambiguities within the expert benchmark itself. Our findings suggest that prompting agents to organize their verification notes in a cautious, human-mathematician-like manner can substantially improve their ability to distinguish rigorous proofs from flawed ones, with the potential to strengthen agentic reasoning on frontier mathematical concepts that the base model does not already know well, and to lay a theoretical foundation for future automated proof-review systems. Code and prompts are available at GitHub.
