Dual normal BCK-algebras

In this paper, by considering the notions of dual right and dual left stabilizers inbounded BCK-algebras, we obtain some related results. After that we investigatethe relationship between the dual left(right) stabilizers and dual ideals in boundedBCK-algebras. Then we define a class of special bounded BCK-algebras calleddual normal BCK-algebras. Finally we prove that the dual semisimple boundedBCK-algebras and dual J-semisimple bounded BCK-algebras are all dual normals.
