A new formulation of the -calculus, where name instantiation is handled explicitly, is presented. The explicit handling of name instantiation allows us to reduce the -calculus transitional semantics to a standard SOS framework. Hence, -calculus bisimulation models can take fully advantage of the SOS metatheory developed for'static' process calculi. For instance, complete axiomatic characterizations of -calculus bisimulation equivalences can be automatically derived by turning SOS rules into
more &raquo; ... tions. Moreover, this formulation of the -calculus is promising for the development of semantic-based automatic veri cation tools. Here we treat in full detail the Late bisimulation semantics. A nite branching labelled transition system and a complete axiomatic characterization of the Late bisimulation equivalence are obtained.
