Abstract. We study the expressiveness of the join calculus by comparison with (generalised, coloured) Petri nets and using tools from type theory. More precisely, we consider four ...
We introduce a new system of trust analysis for concurrent and distributed systems using the π-calculus[13, 14, 15] as a modelling tool. A Type system using boolean annotations g...
We propose the πD -calculus, a process calculus that can flexibly model fine-grained control of resource access in distributed computation, with a type system that statically pr...
Abstract. We consider the problem of specifying and computing consistent answers to queries against databases that do not satisfy given integrity constraints. This is done by simul...

Pi is a system for the interactive construction and editing of formal derivations in the calculus of finitary partial inductive definitions. This calculus can be used as a logical ...
