Despite their widespread adoption as a theoretical tool, though, they still face some unresolved semantic issues, since the standard operational, denotational and logical methods often proved inadequate to reason about these formalisms. A domain which has been successfully employed for languages with asymmetric communication, like the π-calculus, are presheaf categories based on (injective) relabellings, such as SetI. Calculi with symmetric binding, in the spirit of the fusion calculus, give rise to novel research challenges. In this work we examine the explicit fusion calculus, and propose to model its syntax and semantics using the presheaf category SetE, where E is the category of equivalence relations and equivalence preserving morphisms. date: 2012 date_type: published publication: Journal of Automated Reasoning - Special issue on Binding, Substitution and Naming volume: 49 number: 2 publisher: Springer pagerange: 161-183 id_number: 10.1007/s10817-011-9224-3 refereed: TRUE issn: 0168-7433 official_url: http://dx.doi.org/10.1007/s10817-011-9224-3 citation: Bonchi, Filippo and Buscemi, Maria Grazia and Ciancia, Vincenzo and Gadducci, Fabio A Presheaf Environment for the Explicit Fusion Calculus.
