Abstract

Modal mu-calculus is a logic obtained by adding fixpoint operators to ordinary modal logic, or Hennessy-Milner logic. The result is a very expressive logic, sufficient to subsume many other temporal logics such as CTL and CTL✱. The modal mu-calculus is easy to model-check, and so makes a good ‘back-end’ logic for tools; it has an interesting theory, with some major problems still open; but it also has a certain reputation for being hard to read and write.
This tutorial provides an introduction to the modal mu-calculus and related logics, suitable for those with some exposure to modal or temporal logic, but without prior knowledge of fixpoint logics.
I start by reviewing the basic semantic setting of processes modelled as transition systems,and briefly review basic modal logic and temporal logics such as CTL.
I then introduce the modal mu-calculus itself. I cover the formal syntax and semantics, and then give more informally the game-based intuition that is most useful in understanding formula of the logic.
I next describe global and local model-checking techniques.
Finally, I discuss the relationship between modal mu-calculus, automata and games, and some of the theoretical questions that have been and are now of interest.
The tutorial is based around the handbook chapter [1],written with Colin Stirling,which forms the text for the tutorial
