Semantics of name and value passing

Abstract

Provides a semantic framework for (first-order) message-passing process calculi by combining categorical theories of abstract syntax with binding and operational semantics. In particular, we obtain abstract rule formats for name and value passing with both late and early interpretations. These formats induce an initial-algebra/final-coalgebra semantics that is compositional, respects substitution and is fully abstract for late and early congruence. We exemplify the theory with the /spl pi/-calculus and value-passing CCS (calculus of communicating systems).
