Formal Verification of Fermat's Last Theorem in Lean 4 Using Mathlib

#formal_verification #lean_theorem_prover #mathlib #fermats_last_theorem #mathematical_proofs

A machine-checked proof of Fermat's Last Theorem in Lean 4, built on Mathlib, verifies the theorem using standard axioms and two independent kernel checks. The project includes a web-based interactive proof presentation and rigorous formal verification against Mathlib's definitions.
