Abstract: We introduced the concept of Ω-BCK algebras in the framework of fuzzy equalities. Firstly, we replaced the crisp equalities in BCK algebras with fuzzy equalities and gave the definition of Ω-BCK algebras. Secondly, we characterized the substructures of Ω-BCK algebras and proved the necessary and sufficient conditions for the determination of Ω-BCK subalgebras. Thirdly, by using fuzzy congruence relations, we obtained the relationship between Ω-BCK algebras and BCK algebras. Finally, we generalized the partial order relation of BCK algebras and defined the E-partial order relation of Ω-BCK algebras.

Key words: Ω-BCK algebra, complete lattice, fuzzy equality, fuzzy identity, fuzzy subalgebra, E-partial order , relation
