Forward-Reverse Observational Equivalences in CCSK

摘要

In the context of GCSK, a reversible extension of CCS, we study observational equivalences that distinguish forward moves from backward ones. We present a refinement of the notion of forward-reverse bisimilarity and show that it coincides with a notion of forward-reverse barbed congruence. We also show a set of sound axioms allowing one to reason equationally on process equivalences.
