Abstract. We consider the relational characterisation of branching bisimilarity with explicit divergence. We prove that it is an equivalence and that it coincides with the original...
Impossible futures equivalence is the semantic equivalence on labelled transition systems that identifies systems iff they have the same "AGEF" properties: temporal logic...
We give a general framework connecing a branching time relation on nodes of a transition system to a final coalgebra for a suitable endofunctor. Examples of relations treated by o...
