Scalar and Vectorial mu-calculus with Atoms

Logic in Computer Science 2023-06-22 v3

Abstract

We study an extension of modal μ\mu-calculus to sets with atoms and we study its basic properties. Model checking is decidable on orbit-finite structures, and a correspondence to parity games holds. On the other hand, satisfiability becomes undecidable. We also show expressive limitations of atom-enriched μ\mu-calculi, and explain how their expressive power depends on the structure of atoms used, and on the choice between basic or vectorial syntax.
