On Two Higher-Order Extensions of Model Checking

Inspired by the success of finite state model checking in system verification, two kinds of its higher-order extensions have been studied since around 2000. One is model checking of higher-order recursion schemes (HORS), where the language for describing systems to be verified is extended to higher-order, and the other is higher-order fixpoint modal logic (HFL) model checking of finite-state systems, where the logic for specifying properties to be verified is extended to higher-order. The former has been successfully applied to automated verification of higher-order programs. In this talk, I will provide a gentle introduction to the HORS and HFL model checking problems, their applications to software verification, and the state-of-the-art of higher-order model checkers and tools built on top of them. I will also touch upon our recent result on the relationship between HORS and HFL model checking.
