Seventh Annual IEEE Symposium on

Logic in Computer Science (LICS 1992)

Paper: Retracts in simply type λβη-calculus (at LICS 1992)

Authors: Ugo de'Liguoro Adolfo Piperno Richard Statman

Abstract

Retractions existing in all models of simply typed λ-calculus are studied and related to other relations among types, such as isomorphisms, surjections, and injections. A formal system to deduce the existence of such retractions is shown to be sound and complete with respect to retractions definable by linear λ-terms. Results aiming at a system complete with respect to the provable retractions tout court are established
