%0 Journal Article %T Intuitionistic fuzzy ideals of BCK-algebras %A Young Bae Jun %A Kyung Ho Kim %J International Journal of Mathematics and Mathematical Sciences %D 2000 %I Hindawi Publishing Corporation %R 10.1155/s0161171200004610 %X We consider the intuitionistic fuzzification of the concept ofsubalgebras and ideals in BCK-algebras, and investigate some oftheir properties. We introduce the notion of equivalencerelations on the family of all intuitionistic fuzzy ideals of aBCK-algebra and investigate some related properties. %U http://www.hindawi.com/journals/ijmms/2000/307470/abs/
