Hodge and Yang-Mills still lack full Lean formalizations, making near-term solutions less likely

Jsevillamol points out a non-obvious fact: two Millennium Prize Problems — the Hodge conjecture and Yang-Mills existence and mass gap — still lack fully formalized Lean statements.

Without machine-checkable formal statements, he argues, near-term solutions become considerably less likely, though he remains optimistic long-term. He previously proposed "published result with accompanying Lean certificate" as the gold standard for declaring a problem solved, noting about 3 of 5 Clay problems already have accepted Lean formalizations, with the gap expected to close.
