Seminar on normalization by evaluation

"Normalization by Evaluation" (nbe) is an approach to normalization in, as a rule, a certain version of lambda calculus, based on the evaluation in the metalanguage. Namely, a composition of a functional, inversing the evaluator, with that evaluator is an effective procedure for the normalization in the calculus in question. We consider the definition of nbe for basic typed calculi, its extension for the untyped case, and discuss the areas of its application.
