Verification of PCP-Related Computational Reductions in Coq

Logic in Computer Science 2022-12-09 v2 Formal Languages and Automata Theory

Abstract

We formally verify several computational reductions concerning the Post correspondence problem (PCP) using the proof assistant Coq. Our verifications include a reduction of a string rewriting problem generalising the halting problem for Turing machines to PCP, and reductions of PCP to the intersection problem and the palindrome problem for context-free grammars. Interestingly, rigorous correctness proofs for some of the reductions are missing in the literature.
