Logics of Time and Computation

Now revised and significantly expanded, this textbook introduces modal logic and examines the relevance of modal systems for theoretical computer science. Goldblatt sets out a basic theory of normal modal and temporal propositional logics, including issues such as completeness proofs, decidability, first-order definability, and canonicity. The basic theory is then applied to logics of discrete, dense, and continuous time; to the temporal logic of concurrent programs involving the connectives henceforth, next, and until; and to the dynamic logic of regular programs. New material for the second edition extends the temporal logic of concurrency to branching time, studying a system of Computational Tree Logic that formalizes reasoning about behavior. Dynamic logic is also extended to the case of concurrency, introducing a connective for the parallel execution of commands. A separate section is devoted to quantificational dynamic logic. Numerous exercises are included for use in the classroom.Robert Goldblatt is a professor of pure mathematics at the Victoria University of Wellington, New Zealand.
