LASIGE invites Philip Wadler to present next Thursday’s cialis 10mg “Informática @ Ciências” seminar on “Propositions as Sessions”. Besides taking on his lambda-calculus super-hero alter-ego during his very entertaining talks, Philip Wadler is one of most influential researchers on the topic of programming language theory. Recently, he became involved with IOHK, a startup that develops smart-contract technology for blockchains.
Continuing a line of work by Abramsky (1994), by Bellin and Scott (1994), and by Caires and Pfenning (2010), among others, this paper presents CP, a calculus in which propositions of classical linear logic correspond to session types. Continuing a line of work by Honda (1993), by Honda, Kubo, and Vasconcelos (1998), and by Gay and Vasconcelos (2010), among others, this paper presents GV, a linear functional language with session types, and presents a translation from GV into CP. The translation formalises for the first time a connection between a standard presentation of session types and linear logic, and shows how a modification to the standard presentation yield a language free from deadlock, where deadlock freedom follows from the correspondence to linear logic.
