A proof of the mod 4 Kawauchi Conjecture

Jim Conant

Conant proves that for every amphicheiral knot K, its Conway polynomial is congruent modulo 4 to f(z)f(−z) for some integer polynomial f. A stronger integral identity underlies this mod-4 conclusion.

What was already known

Integer factorization was known for certain positive and negative amphicheiral knots, while a counterexample defeated the unrestricted integer conjecture. Conant’s 2006 mod-4 weakening remained open in general.

AI involvement AI-centered

Conant credits Claude Fable 5 with the quotient-tower strategy and level-wise torsion identities. He originated the conjecture, heavily revised the draft, independently verified the central Claude-produced results and wrote the final exposition.

Claude supplied the retained quotient-tower strategy and torsion identities; Conant directed, revised and verified the mathematical work.

Importance Notable

The result closes the mod-4 conjecture for all amphicheiral knots.

Limitations

Conant’s reported independent check excludes Appendix B example calculations; those examples are outside the assessed theorem.

Technical verification Formal (human)

Conant explicitly reports independent verification of Claude-produced results apart from Appendix B examples. This is a completed author check of the mod-4 theorem and its AI-origin proof ingredients, with the example exception kept outside the assessed claim.

Human understanding Full

Conant's extensive revision and detailed explanation of the tower, palindromic normal form and integral identity document a human account of the central mechanism.
