A Temporal Logic of Strategic Knowledge

The paper presents an extension of temporal epistemic logic that adds "strategic" agents in a way that allows standard epistemic operators to capture what agents could deduce from knowledge of the strategies of some subset of the set of agents. A number of examples are presented to demonstrate the broad applicability of the framework, including reasoning about implementations of knowledge-based programs, game theoretic solution concepts and notions from computer security. It is shown that notions from several variants of alternating temporal epistemic logic can be expressed. The framework is shown to have a decidable model checking problem.
