A new study argues that autoformalising natural language mathematical proofs, such as OpenAI's claimed Navier-Stokes blow-up proof, into formal languages like Lean risks semantic disconnection due to unresolvable ambiguities. The translation process is shown to sit at the highest level of the Solvability Complexity Index (SCI), theoretically harder than the Halting problem, implying current AI verification lacks reliability for complex mathematics.

    • Translating natural language math to formal languages by AI risks semantic infidelity, potentially leading to false-positive verifications.
    • Resolving ambiguity in mathematical natural language belongs to the SCI = ∞ hierarchy, computationally harder than the Halting problem with no general solution.
    • Formal verification of OpenAI's Navier-Stokes proof does not automatically validate the correctness of the original natural language argument.
