Center node: "bar recursion in classical realisability dependent choice and continuum hypothesis"
  Abstract: This paper is about the bar recursion operator in the context of classical realizability. The pioneering work of Berardi, Bezem, Coquand was enhanced by Berger and Oliva. Then Streicher has shown, by means of their bar recursion operator, that the realizability models of ZF, obtained from usual models of lambda-calculus (Scott domains, coherent spaces, ...), satisfy the axiom of dependent choice. We give a proof of this result, using the tools of classical realizability. Moreover, we show that these realizability models satisfy the well ordering of R and the continuum hypothesis. These formulas are therefore realized by closed lambda_c-terms. This new result allows to obtain programs from proofs of arithmetical formulas using all these axioms.
