Formalizing Flag Algebras in Lean for Graph Theory Proofs

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a machine-checked formalization of Razborov's flag algebra method within the Lean proof assistant. This formalization enables a compiler that transforms semidefinite programming output into verifiable algebraic proofs. The system has successfully generated formal proofs for seven Turán-type upper bounds, including Mantel's theorem and the Erdős pentagon theorem, as well as density bounds for various graph structures.

    Formalizing Flag Algebras in Lean

    arXiv:2607.23500v1 Announce Type: cross Abstract: Razborov's flag algebra method is a powerful tool for proving asymptotic inequalities in extremal graph theory, often reducing the task to finding a finite certificate by semidefinite programming. We present a machine-checked form…
