Axioms for knowledge and time in distributed systems with perfect recall
Ron van der Meyden · 2002
A distributed system, possibly asynchronous, is said to have perfect recall if at all times each processor's state includes a record of all its previous states. The completeness of a propositional modal logic of knowledge and time with respect to such systems is established. The logic includes modal operators for knowledge, and the linear time operators "next" and "until".>
