A complete axiomatization of interval temporal logic with infinite time

Abstract

Interval temporal logic (ITL) is a formalism for reasoning about time periods. To date no one has proved completeness of a relatively simple ITL deductive system supporting infinite time and permitting infinite sequential iteration comparable to /spl omega/-regular expressions. We give a complete axiomatization for such a version of quantified ITL over finite domains and can show completeness by representing finite-state automata in ITL and then translating ITL formulas into them. The axiom system (and completeness) is extended to infinite time.
