Zusammenfassung:Abstract: "A logical analysis of operational semantics based on the notion of a bisimulation is considered, and the explosion in logical complexity triggered by bisimulations on computable transition predicates is investigated in relation to certain algebraic styles of reasoning. A 'universal mechanical' transition predicate is isolated, accomodating transition predicates departing in essential ways from those underlying various models from denotational semantics. Objections commonly raised against bisimulations (e.g., that bisimilarity is too fine, or that it may fail to be a congruence, or that it is based on transition graphs reducing parallelism to interleaving) are disputed, resting (as these do) on unfortunate choices of transition predicates
For while a bisimulation presupposes a fixed transition predicate, there are a multitude of such predicates, representing (for instance) different levels of abstraction, including input/output equivalence, which, in the context of partial equivalence relations, is presented (below) as a bisimulation.
