Behavioral equivalences have been mainly developed in the context of process algebras, mathematically rigorous languages that have been used for describing and verifying properties of concurrent communicating systems. By relying on the so called structural operational semantics (SOS), labelled transition systems, are associated to each term of a process algebra. Behavioral equivalences are used to abstract from unwanted details and identify those labelled transition systems that react “similarly” to external experiments. Due to the large number of properties which may be relevant in the analysis of concurrent systems, many different theories of equivalences have been proposed in the literature. The main contenders consider those systems equivalent that (i) perform the same sequences of actions, or (ii) perform the same sequences of actions and after each sequence are ready to accept the same sets of actions, or (iii) perform the same sequences of actions and after each sequence exhibit, recursively, the same behavior. This approach leads to many different equivalences that preserve significantly different properties of systems. date: 2011 date_type: published publisher: Springer pagerange: 120-127 pages: 2366 id_number: 10.1007/978-0-387-09766-4_517 refereed: TRUE isbn: 978-0-387-09765-7 book_title: Encyclopedia of Parallel Computing editors_name: Padua, David official_url: http://dx.doi.org/10.1007/978-0-387-09766-4_517 citation: De Nicola, Rocco Behavioral Equivalences.
