%P 79-128 %J ACM Transactions on Computational Logic %T A modal logic for mobile agents %R 10.1145/963927.963930 %D 2004 %A Michele Loreti %A Rocco De Nicola %X 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. This paper presents a temporal logic for specifying properties of Klaim programs. The logic is inspired by Hennessy-Milner Logic (HML) and the ?-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 complete proof system that enables one to prove properties of mobile systems. %L eprints315 %K Coordination Models, Logics, Mobile Code Languages, Mobility, Proof Systems, Temporal Logics of Programs %I ACM %N 1 %V 5
