Model Checking Fixed Point Logic with Chop

Conference paper
Part of the Lecture Notes in Computer Science book series (LNCS, volume 2303)


This paper examines FLC, which is the modal μ-calculus enriched with a sequential composition operator. Bisimulation invariance and the tree model property are proved. Its succinctness is compared to the modal μ-calculus. The main focus lies on FLC’s model checking problem over finite transition systems. It is proved to be Pspace-hard. A tableau model checker is given and an upper Exptime bound is derived from it. For a fixed alternation depth FLC’s model checking problem turns out to be Pspace-complete.
