Gages Accept Concurrent Behavior

Vineet Gupta, Vaughan R. Pratt

Abstract: We represent concurrent processes as Boolean propositions or gates, cast in the role of accepters of concurrent behavior. This properly extends other mainstream representations of concurrent behavior such as event structures, yet is defined more simply. It admits an intrinsic notion of duality that permits processes to be viewed as either schedules or automata. Its algebraic structure is essentially that of linear logic, with its morphisms being consequence-preserving renamings of propositions, and with its operations forming the core of a natural concurrent programming language.<
