A Uniform presentation of chocs and p-calculus
Résumé
We present a generic calculus of "mobile" processes intended as language, labelled transition system, and bisimulation. The distinctive feature of this presentation is an explicit treatment of contexts. Calculi having processes (CHOCS) or channels (p-calculus) as transmissible values are obtained as instances of the generic calculus. Our main tecnical contributions are : - a needed weakening of the notion of bisimulation for CHOCS and a new characterization of p-calculus bisimulation. - a sufficint condition for checking the bisimilarity of CHOCS processes via a standard translation into the p-calculus. - a uniform notion of bisimulation for the p-calculus.
