Abstract: Event structures are models of processes as events constrained by relations of consistency and enabling. These notes are intended to introduce the mathematical theory of event structures, show how they are related to Petri nets and Scott domains, and how they can be used to provide semantics to programming languages for parallel processes as well as languages with higher types.
