Abstract:
Sequent calculus for the provability logic $\mathsf{GL}$ is considered, in which provability is based on the notion of a circular proof. Unlike ordinary derivations, circular proofs are represented by graphs allowed to contain cycles, rather than by finite trees. Using this notion, we obtain a syntactic proof of the Lyndon interpolation property for $\mathsf{GL}$.
Keywords:
provability logic, sequent calculus, circular proof, the Gödel–Löb logic, the Lyndon interpolation property, split sequent.
