arXiv:2606.31002v1 Announce Type: cross Abstract: Theorem-proving benchmarks evaluate proof search against fixed formal statements, but natural-language-to-Lean formalization must generate the formal statement itself. In this setting, compilation is only a validity check: a Lean declaration may type-check while omitting hypotheses, changing domains, or expressing a vacuous claim. We study faithful statement formalization as both an evaluation problem and a bottleneck-attribution problem. On a 400-entry graduate-level benchmark spanning real analysis, complex analysis, topology, and algebra, ou
The proliferation of advanced AI models has accelerated research into their capabilities for complex reasoning and formal verification, making evaluation of their logical faithfulness a critical next step.
This research addresses a core limitation of current AI in formal reasoning, moving beyond simple code generation to ensuring logical validity and correctness, which is fundamental for trustworthy automated theorem proving.
The focus is shifting from merely generating syntactically correct formal statements to evaluating their semantic faithfulness to natural language intent, introducing new benchmarks for higher-order reasoning in AI.
