My talk will be a survey of recent results about the quest for a logic capturing polynomial time. In a fundamental study of database query languages, Chandra and Harel [4] first ra...
In distributed environments, statements from a number of principals, besides the central trusted party, may influence the derivations of authorization decisions. However, existin...
Abstract. The logic FO(ID) uses ideas from the field of logic programming to extend first order logic with non-monotone inductive definitions. The goal of this paper is to exten...
Functional logic languages combine the operational principles of the most important declarative programming paradigms, namely functional and logic programming. Inductively sequent...
Abstract. In this paper we consider the relationship between refinement-oriented specification and specifications using a temporal logic. We investigate the extent to which one can...
