Concurrency Theory changed a lot in the course of the years, almost no paper presented the same axiomatic system as the previous one. In addtion to a set of core axioms there are many other axioms that might be useful, some of which are evalutated in this work.
Some strange models of Concurrency Theory are presented, because they illuminate the need for additional axioms that can ensure long held beliefs about concurrency structures.
It is not the aim of this thesis to develop the theory from its roots, as it is done in the works of Petri. We will focus our main interest on the interrelations of the axioms and on some useful axiomatic systems
