On the λ Definable Higher Order Boolean Operations

Abstract

The purpose of this work is to show the methods of representing higher order boolean functionals in the simple typed λ calculus. In the paper is presented an algorithm for construction the λ representation of a functional given by generalized truth table. This technique is useful especially in functional programming languages such as ML in which functionals are expressed in the form of typed λ terms. Also λ representability of higher order functionals in many valued logics is discussed.
