MoMo: A Modal Logic for Reasoning About Mobility

A temporal logic is proposed as a tool for specifying properties of Klaim programs. Klaim is an experimental programming language that supports a programming paradigm where both processes and data can be moved across different computing environments. The language relies on the use of explicit localities. The logic is inspired by Hennessy-Milner Logic (HML) and the μ–calculus, but has novel features that permit dealing with state properties and impact of actions and movements over the different sites. The logic is equipped with a sound and complete tableaux based proof system.
