Astra produces Lean disproofs of Smale's and Köthe conjectures
basedjensen · x · 2026-09-05
According to tmkadamcz, Astra produced Lean disproofs of Smale's mean value conjecture (1981) and the Köthe conjecture (1930), at least as stated in the Formal Conjectures repo. Other AIs he consulted judge the results legitimate rather than misformalizations, though the author says he is not competent to verify them himself. Links are in the replies. If confirmed, this would be a notable milestone for AI-driven formal mathematics.
