However, they also have some disadvantages: they are based on a sequential operational semantics defined by means of an ordinary transition system, and in order to be bisimilar two systems have to be “too similar”. In this work we will present several natural proposals to define weaker bisimulation semantics that we think properly capture the desired behaviour of distributed systems. The main virtue of all these semantics is that they are real bisimulation semantics, thus inheriting most of the good properties of bisimulation semantics. This is so because they can be defined as particular instances of Jacobs and Hughes’ categorical definition of simulation, which they have already proved to satisfy all those properties.engbook parthttps//doi.org/10.1007/978-3-540-73196-2_10http://link.springer.com/content/pdf/10.1007%2F978-3-540-73196-2_10open access004Informática (Informática)1203.17 Informática
