Abstract

We investigate the conceptual link between action refinement for a process algebra which contains the TCSP-parallel composition operator and recursion on the one hand and action refinement for the Hennessy-Milner-Logic on the other. We show that the assertion P = ϕ P[a→ Q] = ϕ[a → Q] where ċ[a → Q] denotes the refinement operator both on process terms and formulas holds in the considered framework under weak and reasonable restrictions.
