The Faithfulness Gap: Certifying Semantic Equivalence Between Natural-Language and Formal Mathematical Statements
arXiv:2606.16541v1 Announce Type: new Abstract: Autoformalization, translating natural-language mathematics into formal proof assistants, is bottlenecked not by translation fluency but by \emph{faithfulness}: a formal statement can typecheck and be provable, yet still encode a different theorem than the source intended. We introduce \emph{Bidirectional Provability Fingerprinting} (\bpf{}), a framework that certifies faithfulness by characterizing each candidate through its forward and backward consequence neighborhoods in the ambient theory and matching these against probes derived from the na
This research addresses a critical bottleneck in autoformalization which is becoming increasingly relevant as AI advances in mathematical reasoning and proof generation.
Ensuring semantic equivalence between natural language and formal mathematical statements is crucial for reliable AI-driven theorem proving and scientific discovery, impacting fields from software verification to drug design.
The ability to certify faithfulness could accelerate the adoption and trustworthiness of AI tools in formal mathematics, moving beyond mere syntactic correctness to semantic fidelity.
