Abstract

A sound and complete axiomatic system and a tableau-based decision procedure are presented for propositional temporal logic over linear and discrete time models. The axiomatic system and decision procedure are presented for the full logic, including the past operators, but contain a clear identification of the parts whose omission yields axiomatization and a decision procedure for the future fragment. The paper summarizes work of over 20 years and is intended to provide a definitive reference to the version of propositional temporal logic used for the specification and verification of reactive systems
