Abstract
In this paper, we consider a class of special subsets of a $BCK$-algebra and investigate some related properties. We describe the intersection and union of two of these subsets in a commutative $BCK$-lattice. We consider the intersection of all special subsets in a $BCK$-algebra and investigate some related properties. Finally, we introduce the connection between the class of special subsets and the set of all congruence classes induced by an ideal in a $BCK$-algebra.
