Abstract: The intention of the paper is to study prime event structures as models of nondeterministic processes. We characterize and examine some properties know n as discreteness, density and crossing which allow inconsistency to be avoided between syntactic and semantic representations of processes. A number of close relationships between density and crossing properties of the chosen class of event structures are shown.
