    ABSTRACT

    The paper presents a relatively complete deductive system for proving branching time temporal properties of reactive programs. No deductive system for verifying branching time temporal porperties has been presented before. Our deductive system enjoys the following advantages. First, given a well-formed specification there is no need to translate it into a normal-form specification since the system can handle any well-formed specification. Second, given a specification to be verified, the proof rule to be applied is easily determined according to the top level operator of the specification. Third, the system reduces temporal verification to assertional reasoning rather than to temporal reasoning.

    Keywords: program verification, temporal logic, branching-time, CTL, deductive system.
