Comments on the paper of Michel Tatu (2)rent constraint languages and CSP with asynchronous channels. The main characteristic of these languages is that processes interact by reading and modifying the state of some common data structure. We abstract from the specific features of the various communication mechanisms by means of a uniform l

This dependency on the set of actions the environment is ready to perform goes beyond that encountered in traditional CCS. Its expression is realised by an operational semantics in which transitions carry ready-sets (of the environmen

We show that in fact two incompatible process models are used, and we devise a new model that has all essential characteristics of the two former models. A complete axiomatization of this model is given. It is shown that a distinction betwe

For concurrent and distributed systems, instead, there is no well accepted metalanguage to describe the possible observations of the behaviour of programs. The proper treatment of observations is thus an important and complex issue of concurrency theory. In this paper we show that ob

Comments on the paper of Michel Tatu (1)of Free Choice nets, and characterise the compositions (within this class) that preserve liveness (absence of partial or global deadlocks) and boundedness (absence of overflows in finite stores). The characterisation shows which structures must be avoided in order to preserve the properties.

Formal techniques for parallel object-oriented languages,nd several related languages. We sketch a number of semantic descriptions, using several formalism: operational semantics, denotational semantics, and a new approach to semantics, which we call .. Then we summarize the progress that has been made in formal proof systems to verify the correctness of
