Axioms for Real-Time Logics


Jean-Francois Raskin, Pierre-Yves Schobbens, and Thomas A. Henzinger

This paper presents a complete axiomatization of two decidable propositional real-time linear temporal logics: Event Clock Logic (ECL) and Metric Interval Temporal Logic with past (MITL). The completeness proof consists of an effective proof building procedure for ECL. From this result we obtain a complete axiomatization of MITL by providing axioms translating MITL formulae into ECL formulae, the two logics being equally expressive. Our proof is structured to yield axiomatizations also for interesting fragments of these logics, such as the linear temporal logic of the real numbers (LTR).
