Introduction
This research project aims to investigate the central issues of research on accessibility, model verification and equivalence verification of models of infinite state systems that model competition. This field of research is young and active on the one hand, but also complex and very poorly understood on the other. Our objective is to better understand the algorithmic behaviour of simultaneous infinite state systems with respect to the formal verification tasks mentioned above.
In a very general way, we would like to answer the following questions. First, when is the respective verification task decidable, i.e. when can it be solved efficiently on a computer? Second, if the respective verification task is decidable, how many resources in terms of time and space are sufficient and necessary to solve it on a computer?
