A category of event structures with symmetry is introduced and its categorical properties investigated. Applications to the event-structure semantics of higher order processes, no...
We consider nested nets, i.e. Petri nets in which tokens can be Petri nets themselves. We study value semantics of nested nets rather than reference semantics, and apply nested ne...

We study the complexity of the reachability problem for a new subclass of Petri nets called simple-circuit Petri nets, which properly contains several well known subclasses such as...
Object Petri nets (OPNs) provide a natural and modular method for modelling many real-world systems. We give a structure-preserving translation of OPNs to Prolog by encoding the O...
