Title
On Principal Types of BCK- lambda -Terms
Abstract
Condensed BCK-logic, i.e. the set of BCK-theorems provable by the condensed detachment rule of Carew Meredith, has been shown to be exactly the set of principal types of BCK-lambda-terms. In 1993 Sachio Hirokawa gave a characterization of the set of principal types of BCK-A-terms in beta-normal form based on a relevance relation that he defined between the type variables in a type. We define a symmetric notion of this and call it dependence relation. Then, using the notion of,beta(s)-reduction introduced by de Groote, we obtain a characterization of the complete set of principal types of BCK-lambda-terms.
