Abstract

This paper offers a complete inference system for branching bisimulation congruence on a basic sublanguage of CCS for representing regular processes with silent moves. Moreover, complete axiomatizations are provided for the guarded expressions in this language, representing the divergence-free processes, and for the recursion-free expressions, representing the finite processes. Furthermore it is argued that in abstract interleaving semantics (at least for finite processes) branching bisimulation congruence is the finest reasonable congruence possible. The argument is that for closed recursion-free process expressions, in the presence of some standard process algebra operations like partially synchronous parallel composition and relabelling, branching bisimulation congruence is completely axiomatized by the usual axioms for strong congruence together with Milner's first τ-law aτ X=aX.
