Fusion is commonly regarded as a generalisation of pi-calculus. Actually, we prove that there is no uniform fully abstract embedding of pi-calculus into Fusion. This fact motivates the introduction of a new calculus, D-Fusion, with two binders, λ and ν. We show that D-Fusion is strictly more expressive than both pi-calculus and Fusion. The expressiveness gap is further clarified by the existence of a fully abstract encoding of mixed guarded choice into the choice-free fragment of D-Fusion. date: 2004 date_type: published series: Lecture Notes in Computer Science volume: 3302 publisher: Springer pagerange: 296-310 id_number: 10.1007/978-3-540-30477-7_20 refereed: TRUE isbn: 3-540-23724-0 book_title: Proceedings of the Second Asian Symposium on Programming Languages and Systems (APLAS’04) editors_name: Chin, Ngan official_url: http://dx.doi.org/10.1007/978-3-540-30477-7_20 funders: Research partially supported by FET-Global Computing projects PROFUNDIS and MIKADO. citation: Boreale, Michele and Buscemi, Maria Grazia and Montanari, Ugo D-Fusion: A Distinctive Fusion Calculus.
