New Human-AI Harness FYAN Enhances Mathematical Formalization

By PulseAugur Editorial · [1 sources] ·

Researchers have developed FYAN, a novel human-AI system designed for the document-level formalization of mathematical theorems. FYAN integrates a comprehensive workflow from specification and proof planning to logical review and Lean proof construction, incorporating semantic auditing to ensure formal statements accurately reflect their informal specifications. Using the DeepSeek-V4.1-Flash model, FYAN demonstrated superior performance on FormalTCS theorems compared to a general agent harness and improved natural-language proof scores. The system also proved effective in identifying inconsistent statements on ConsistencyCheck and contributed to the creation of a substantial Lean library for ordinary differential equation analysis. AI

IMPACT This system could advance the accuracy and efficiency of formalizing complex mathematical documents, potentially impacting fields requiring rigorous mathematical proof.

    Fyan: A Human--AI Harness with Semantic Auditing for Document-Level Formalization

    arXiv:2609.39228v1 Announce Type: new Abstract: We present FYAN, a human--AI harness for document-level mathematical formalization. Rather than treating theorems in isolation, FYAN coordinates an end-to-end workflow spanning specification, proof planning, logical review, Lean pro…
