Center node: "standardization and conservativity of a refined call by value lambda calculus"
  Abstract: We study an extension of Plotkin's call-by-value lambda-calculus via two#N#commutation rules (sigma-reductions). These commutation rules are sufficient to#N#remove harmful call-by-value normal forms from the calculus, so that it enjoys#N#elegant characterizations of many semantic properties. We prove that this#N#extended calculus is a conservative refinement of Plotkin's one. In particular,#N#the notions of solvability and potential valuability for this calculus coincide#N#with those for Plotkin's call-by-value lambda-calculus. The proof rests on a#N#standardization theorem proved by generalizing Takahashi's approach of parallel#N#reductions to our set of reduction rules. The standardization is weak (i.e.#N#redexes are not fully sequentialized) because of overlapping interferences#N#between reductions.
