Semantics for Concurrency

The semantics of concurrent systems is one of the most vigorous areas of research in theoretical computer science, but suffers from disagree­ ment due to different, and often incompatible, attitudes towards abstracting non-sequential behaviour. When confronted with process algebras, which give rise to very elegant, highly abstract and com­ positional models, traditionally based on the interleaving abstraction, some argue that the wealth of contribution they have made is partially offset by the d
