We compare the expressive power of two automata-based finite-state models of concurrency. We show that Droste’s and Kuske’s coherent stably concurrent automata and Bednarczyk...
Abstract. We define and study an automata model of concurrent recursive programs. An automaton consists of a finite number of pushdown systems running in parallel and communicati...

We relate several models of concurrency introduced in the literature in order to extend classical Mazurkiewicz traces. These are mainly Droste's concurrent automata and Arnold...
We define reactive simulatability for general asynchronous systems. Roughly, simulatability means that a real system implements an ideal system (specification) in a way that pre...
We consider temporal aspects of self-replication and evolvability – in particular, the massively asynchronous parallel and distributed nature of living systems. Formal views of s...
