Paper: Modal µ-Types for Processes (at LICS 1995)

Authors: Marino Miculan Fabio Gadducci


We introduce a new paradigm for concurrency, called behaviors-as- types. In this paradigm, types are used to convey information about the behavior of processes: while terms corresponds to processes, types correspond to behaviors. We apply this paradigm to Winskel's Process Algebra. Its types are similar to Kozen's modal \mu-calculus; hence, they are called modal \mu-types}. We prove that two terms having the same type denote two processes which behave in the same way, that is, they are bisimilar. We give a sound and complete compositional typing system for this language. Such a system naturally recovers the notion of bisimulation also on open terms, allowing us to deal with processes with undefined parts in a compositional manner.
