Model Checking with Finite Complete Prefixes Is PSPACE-Complete
Unfoldings are a technique for verification of concurrent and distributed systems introduced by McMillan. The method constructs a finite complete prefix, which can be seen as a sym...

Complexity Results for 1-safe Nets
We study the complexity of several standard problems for 1-safe Petri nets and some of its subclasses. We prove that reachability, liveness, and deadlock are all PSPACE-complete f...

Answer Set Programming and Bounded Model Checking
In this paper bounded model checking of asynchronous concurrent systems is introduced as a promising application area for answer set programming. This is an extension of earlier w...

Modelchecking counting properties of 1-safe nets with buffers in paraPSPACE
ABSTRACT. We consider concurrent systems that can be modelled as 1-safe Petri nets communicating through a fixed set of buffers (modelled as unbounded places). We identify a param...
