Center node: "bar recursion in classical realisability dependent choice and well ordering of r"
  Abstract: This paper is about the  bar recursion operator in the context of classical realizability. After the pioneering work of Berardi, Bezem & Coquand [1],#R##N#T. Streicher has shown [10], by means of their bar recursion operator, that the realizability models of ZF, obtained from usual models of λ-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 λc-terms. This allows to obtain programs from proofs of arithmetical formulas using all these axioms.
