In a previous paper, we developed an algebraic theory of threads, interleaving of threads, and interaction between threads and services. In the current paper, we extend that theory...
Abstract. An invariant of a system is a predicate that holds for every reachable state. In this paper, we present techniques to generate invariants for hybrid systems. This is achi...
Abstract. This is a short survey illustrating some of the essential aspects of the theory of canonical extensions. In addition some topological results about canonical extensions o...
This paper is a guided tour through the theory of fibring as a general mechanism for combining logics. We present the main ideas, constructions and difficulties of fibring, from ...
We present complexity results for the verification of security protocols. Since the perfect cryptography assumption is unrealistic for cryptographic primitives with visible algebr...
