Eleventh Annual IEEE Symposium on

Logic in Computer Science (LICS 1996)

Paper: Reduction-free normalisation for a polymorphic system (at LICS 1996)

Authors: Thorsten Altenkirch Martin Hofmann Thomas Streicher

Abstract

We give a semantical proof that every term of a combinator version of system F has a normal form. As the argument is entirely formalisable in an impredicative constructive type theory a reduction-free normalisation algorithm can be extracted from this. The proof is presented as the construction of a model of the calculus inside a category of presheaves. Its definition is given entirely in terms of the internal language.
