Napaw 92

This volume contains papers from the North American Process Algebra Workshop, held in Stony Brook, New York, 28 August 1992. This was the first in a proposed series of workshops, intended to increase awareness of process algebras in the United States and Canada, and to promote their use and development. The workshop was held simultaneously with CONCUR 92, the annual conference on concurrency theories. It provided an important forum for the discussion and exchange of ideas, and allowed recent developments in the application of algebraic techniques to concurrency theory to be presented. The resulting volume provides a good cross-section of current research work in Canada, USA and Europe. Among the specific topics covered are: real-time calculi and expansion theorems; modal logics in timed process algebra; process communication environment; a process calculus with incomparable priorities; exception handling in process algebra; bisimulations on observation structures; computing ready simulations efficiently; analysis of value-passing CCS agents with infinite sorts; an extension of the testing method for processes passing infinite values; constructive semantics; a causality-based semantics for CCS. NAPAW 92 provides an comprehensive overview of this important, up-and-coming area of computer science. It will provide essential reading for both postgraduate students and researchers in industry and academia.
