Symmetries are inherent in systems that consist of several interchangeable objects or components. When reasoning about such systems, big computational savings can be obtained if t...

In this paper we propose a behavioural model, namely the Generalized Extended Modal Transition Systems, as a basis for the formalization of different notions of variability usuall...

Petri net schemata are an intuitive and expressive approach to describe high-level Petri nets. A Petri net schema is a Petri net with edges and transitions inscribed by terms and B...

This paper deals with verification methods based on equivalence relations between labeled transition systems. More precisely, we are concerned by two practical needs: how to effi...

We here consider transition systems of Elementary Net Systems with Inhibitor Arcs. There are basically two di erent types of non-interleaving semantics of such Petri nets, the a-po...

We take the point of view that, if transition systems are coalgebras for a functor T, then an adequate logic for these transition systems should arise from the `Stone dual' L ...

Abstract. Models for concurrency can be classified with respect to three relevant parameters: behaviour/system, interleaving/noninterleaving, linear/branching time. When modelling...
