Of special interest in formal verification are safety properties, which assert that the system always stays within some allowed region. Each safety property can be associated with...
Abstract. Logics of knowledge have important applications for reasoning about security protocols and multi-agent systems. We extend the semantics for the logic of necessity with lo...
Abstract. Since the advent of model checking it is becoming more common for languages to be given a semantics in terms of transition systems. Such semantics allow to model check pr...
