Résumé: Configuration Structures
Description: Clément Aubert A standard contextual equivalence for process algebras is strong barbed congruence. Configuration structures are a denotational semantics for processes in which one can define equivalences that are more discriminating, i.e. that distinguish the denotation of terms equated by barbed congruence. Hereditary history preserving bisimulation (hhpb) is such a relation. We define a strong back and forth barbed congruence using a reversible process algebra and show that the relation induced by the back and forth congruence is equivalent to hhpb. Hence we give a characterization of hhpb as a contextual equivalence in a reversible process algebra.
