UNITY and Büchi automata

Abstract UNITY is a model for concurrent specifications with complete logic proving progress properties of the form “ P leads to Q ”. generalized U-specifications by giving more freedom specify steps that are be taken infinitely often. In particular, these can correspond non-total relations. The generalization keeps sound and complete. paper exploits in two ways. Firstly, remains when specification extended hypotheses F G As shows, this make incomplete. used show complete, if added ” satisfy unless main result extends applicability completeness proofs given program satisfies any formula LTL, linear temporal logic, without next-operator which omitted because it sensitive stuttering. For purpose, program, written as number boolean variables. proof method relies on implementing LTL formula, i.e., restricting such way only those runs remain formula. This variation classical construction Büchi automatonfor accepts precisely
