Abstract

In this paper we define a semantic foundation for an abstract interpretation approach to universal termination and we develop a new abstract domain useful for termination analysis. Based on this approximation we define a method which is able to detect classes of goals which universally terminate (with a fair selection rule). We also define a method which is able to characterize classes of programs and goals for which depth-first search is fair.
