Lean Golf is a code golf competition where participants prove mathematical theorems using the Lean proof assistant. The course contains problems of varying difficulty, from medium challenges involving combinatorics and number theory to hard problems about the Fibonacci sequence and the Jacobian conjecture.
An AI will eventually produce mathematical papers of such complexity that only other AIs can fully verify them, with human mathematicians able to follow only the first few pages. The work will be formalized in advanced proof assistants, and AIs will continue generating increasingly inaccessible mathematics building on previous results, potentially solving long-standing conjectures like the Riemann hypothesis with elementary proofs incomprehensible to humans.
