In order to check whether an open system satisfies a desired property, we need to check the behavior of the system with respect to an arbitrary environment. In the most general se...
We show that characteristic formulae for nite-state systems up to bisimulationlike equivalences (e.g., strong and weak bisimilarity) can be given in the simple branching-time temp...
Nested Pushdown Trees are unfoldings of pushdown graphs with an additional jump-relation. These graphs are closely related to collapsible pushdown graphs. They enjoy decidable µ-c...
The Brane Calculus is a calculus intended to model the structure and the dynamics of biological membranes. In order to express properties of systems in this calculus, in previous ...
Abstract. Default logic is one of the most widely used formalisms to formalize commonsense reasoning. In this paper we analyze the complexity of deciding whether a propositional in...
