Using the notions of left and right derivations in d/BCK-algebras, we show that the set of all cycles forms a right ideal of a d-algebra, and show that the right translation maps become an (r,l)-derivation on BCK-algebras. Moreover, we discuss some properties on cycles and polynomial elements in d/BCK-algebras.
Keywords : d/BCK-algebra, (r,l)((l,r))-derivation, Excision, Cycle, Polynomial element
