On nd-K* (n, r)-Full Hypersubstitutions

Abstract

Abstract Based on the notion of K* (n, r)-full terms defined by the authors, nd- K* (n, r)-full hypersubstitutions are defined. It turns out that the extension of an nd- K* (n, r)-full hypersubstitution is an endomorphism of the algebra of tree languages of nd- K* (n, r)-full terms.
