Abstract

The clausal resolution method for propositional linear-time temporal logics is well known and provides the basis for a number of temporal provers. The method is based on an intuitive clausal form, called SNF, comprising three main clause types and a small number of resolution rules. In this paper, we show how the normal form can be radically simplified and, consequently, how a simplified clausal resolution method can be defined for this important variety of logic.
