TY - JOUR A1 - Desharnais, Jules A1 - Möller, Bernhard T1 - Non-associative Kleene algebra and temporal logics T2 - Lecture Notes in Computer Science N2 - We introduce new variants of Kleene star and omega iteration for the case where the iterated operator is neither associative nor has a neutral element. The associated repetition algebras are used to give closed semantic expressions for the Until and While operators of the temporal logic CTL* and its sublogics CTL and LTL. Moreover, the relation between the semantics of these logics can be expressed by homomorphisms between repetition algebras, which is a more systematic and compact approach than the ones taken in earlier papers.
