TL;DR
An algebra of labelled event structures whose operations are sequential composition, sum, and parallel composition is introduced and it is claimed that the bisimulation relative to such transition systems brings out a clean distinction between concurrency and sequential non-determinism.
Abstract
We introduce an algebra of labelled event structures whose operations are sequential composition, sum, and parallel composition. A transition relation is defined on these objects, where at each step a process performs a labelled poset. It is claimed that the bisimulation relative to such transition systems brings out a clean distinction between concurrency and sequential non-determinism.
