We present a categorical theory of ‘well-behaved’ operational semantics which aims at complementing the established theory of domains and denotational semantics to form a cohe...
Kowalski and Sergot’s Event Calculus (EC) is a simple temporal formalism that, given a set of event occurrences, allows the derivation of the maximal validity intervals (MVIs) o...
Abstract. We show that non-determinism simplifies coding certain problems into programs. We define a non-confluent, but well-behaved class of rewrite systems for supporting non-...
We dene a perpetual one-step reduction strategy which enables one to construct minimal (w.r.t. Levy's ordering 2 on reductions) innite reductions in Conditional Orthogonal ...
Abstract. Milner introduced action calculi as a framework for investigating models of interactive behaviour. We present a type-theoretic account of action calculi using the proposi...
