Persistent sets are a cornerstone of Partial Order Reduction; however, they need to be combined with additional methods (such as sleep sets) to avoid the state-space-explosion problem, e.g., in deadlock detection. However, one crucial fact is that persistent *singletons* are "inessential" in a suitable, technical sense; thus, the goal is to eliminate them "directly". Roughly, we can render asynchronous transition systems more compact by "quotienting out" all persistent singletons, using techniques of directed algebraic topology. The talk illustrates the crucial ideas for the case of occurrence nets and focuses on the relation to Haar's facet abstraction.
