Decidability Problems for Actor Systems
We introduce a nominal actor-based language and study its expressive power. We have identified the presence/absence of fields as a relevant feature: the dynamic creation of names...

Avoiding Shared Clocks in Networks of Timed Automata
Networks of timed automata (NTA) are widely used to model distributed real-time systems. Quite often in the literature, the automata are allowed to share clocks. This is a problem ...

MSO Decidability of Multi-Pushdown Systems via Split-Width
Abstract. Multi-threaded programs with recursion are naturally modeled as multi-pushdown systems. The behaviors are represented as multiply nested words (MNWs), which are words enr...
