Center node: "typed realizability for first order classical analysis"
  Abstract: We describe a realizability framework for classical first-order logic in#N#which realizers live in (a model of) typed {\lambda}{\mu}-calculus. This allows#N#a direct interpretation of classical proofs, avoiding the usual negative#N#translation to intuitionistic logic. We prove that the usual terms of G\"odel's#N#system T realize the axioms of Peano arithmetic, and that under some#N#assumptions on the computational model, the bar recursion operator realizes the#N#axiom of dependent choice. We also perform a proper analysis of relativization,#N#which allows for less technical proofs of adequacy. Extraction of algorithms#N#from proofs of {\Pi}02 formulas relies on a novel implementation of Friedman's#N#trick exploiting the control possibilities of the language. This allows to have#N#extracted programs with simpler types than in the case of negative translation#N#followed by intuitionistic realizability.
