Abstract. This paper investigates an approach to substitution alternative to the implicit treatment of the λ-calculus and the explicit treatment of explicit substitution calculi. ...
Bigraphical Reactive Systems have been proposed as a meta model for global ubiquitous computing generalising process calculi for mobility such as the pi-calculus and the Mobile Amb...
Abstract Neil Ghani Valeria de Paiva Eike Ritter The -calculus 1 adds explicit substitutions to the -calculus so as to provide a theoretical framework within which the implement...
We introduce the notion of higher dimensional transition systems as a model of concurrency providing an elementary, set-theoretic formalisation of the idea of higher dimensional t...
Abstract. The λ-calculus with de Bruijn indices, called λdB, assembles each α-class of λ-terms into a unique term, using indices instead of variable names. Intersection types p...
