Abstract
We address abstraction in the setting of probabilistic reactive systems, and study its formal underpinnings for the strictly alternating model. In particular, we define the notion of branching bisimilarity and study its properties by studying two other equivalence relations, viz. coloured trace equivalence and branching bisimilarity using maximal probabilities. We show that both alternatives coincide with branching bisimilarity. The alternative characterisations have their own merits and focus on different aspects of branching bisimilarity. Together they give a better understanding of branching bisimilarity. A crucial observation, and, in fact a major motivation for this work is that the notions of branching bisimilarity in the alternating and in the non-alternating model differ, and that the latter one discriminates between systems that are intuitively branching bisimilar.
