摘要
We develop a theory of bisimulation equivalence for the broadcast calculus CBS. Both the strong and weak versions of bisimulation congruence we study are justified in terms of a characterisation as the largest CBS congruences contained in an appropriate version of barbed bisimulation. We then present sound and complete proof systems for both the strong and weak congruences over finite terms. The first system we give contains an infinitary proof rule to accommodate input prefixes. We improve on this by presenting a finitary proof system where judgements are relative to properties of the data domain. (C) 1998-Elsevier Science B.V. All rights reserved.
