Note on the Tableau Technique for Commutative Transition Systems

We define a class of transition systems called effective commutative transition systems (ECTS) and show, by generalising a tableaubased proof for BPP, that strong bisimilarity between any two states of such a transition system is decidable. It gives a general technique for extending decidability borders of strong bisimilarity for a wide class of in.nite-state transition systems. This is demonstrated for several process formalisms, namely BPP process algebra, lossy BPP processes, BPP systems with interrupt and timed-arc BPP nets.
