Center node: "an explicit framework for interaction nets"
  Abstract: Interaction nets are a graphical formalism inspired by Linear Logic#N#proof-nets often used for studying higher order rewriting e.g. \Beta-reduction.#N#Traditional presentations of interaction nets are based on graph theory and#N#rely on elementary properties of graph theory. We give here a more explicit#N#presentation based on notions borrowed from Girard's Geometry of Interaction:#N#interaction nets are presented as partial permutations and a composition of#N#nets, the gluing, is derived from the execution formula. We then define#N#contexts and reduction as the context closure of rules. We prove strong#N#confluence of the reduction within our framework and show how interaction nets#N#can be viewed as the quotient of some generalized proof-nets.
