Processes as formal power series: A coinductive approach to denotational semantics
@ARTICLE{BG:TCS2006:PFPSCADS,
title = {{Processes as formal power series: A coinductive approach to denotational semantics}},
author = {{Michele} {Boreale} and {Fabio} {Gadducci}},
journal = {Theoretical Computer Science},
pages = {440-458},
abstract = {We characterize must testing equivalence on CSP in terms of the unique homomorphism from the Moore automaton of CSP processes to the final Moore automaton of partial formal power series over a certain semiring. The final automaton is then turned into a CSP- algebra: operators and fixpoints are defined, respectively, via behavioural differential equations and simulation relations. This structure is then shown to be preserved by the final homomorphism. As a result, we obtain a fully abstract compositional model of CSP phrased in purely set-theoretical terms.},
