We present a process calculus where synchronous composition is the central algebraic notion; equivalences between processes via bisimilarity or trace can be studied quite simply i...
This is a self-contained paper which introduces a fundamental problem
in the calculus of variations, the problem of nding extreme values
of functionals. The reader should have a...
This paper proposes a new calculus for expressing the behaviour of object-oriented systems. The semantics of the calculus is given in terms of operators from computational categor...
We develop the static and dynamic semantics of PiDuce, a process calculus with XML values, schemas, and pattern matching. PiDuce values include channel names, therefore the structu...

Kowalski and Sergot's Event Calculus (EC) is a formalism for reasoning about time and change in a logic programming framework. From a description of events which occur in the...
