Stokes' theorem formalized in Lean 4 with true pullbacks and d²=0 proof

basedjensen · x · 2026-09-11

Stokes' theorem has been formalized in Lean 4, using true pullbacks via Fréchet derivatives and including a proof of d²=0. Formalizing this core of differential geometry means a central result of the field is now machine-verifiable, raising the reliability bar for mathematics.
