Abstract

The paper presents a sound and (relatively) complete deductive proof system for the verification of CTL* properties over possibly infinite-state reactive systems.T he proof system is based on a set of proof rules for the verification of basic CTL* formulas, namely CTL* formulas with no embedded path quantifiers.W e first show how to decompose the proof of a general (non-basic) CTL* formula into proofs of basic CTL* formulas.W e then present proof rules for some of the most useful basic CTL* formulas, then present a methodology for transforming an arbitrary basic formula into one of these special cases.
