| In this note, at first, we point out on important error in Meference [2] . Next, we give a class of new dual ideals which is exactly dual to the ideals introduced by Is'eki [ 7 ].we also construct the guotient algebra with respect to these dual ideals and study some of their important properties. Moreover, we show that in setting of boun-ded implicative BCK-algebras, our results will imply those of [2] §4 , and so the error of [ 2] is corrected. |
