Abstract
An interval-valued fuzzy set denotes a fuzzy set whose membership function is many -valued and form an interval in the member ship scale. The notion of cubic sets as an extension of fuzzy set in which not only a membership degree is given but also a non-membership degree is involved. In this present study, we introduce the concept of cubic fuzzy positive implicative ideals, cubic fuzzy positive implicative extension ideals in BCK-algebras and investigate some of its properties.
Keywords: BCK-algebras, fuzzy positive implicative ideal, fuzzy positive implicative extension ideals.
