in this paper, we define the concepts of fuzzifying subalgebras, fuzzifying ideals, and fuzzifying implicative ideals in bck-algebras and discuss their properties and relations among them.
在bck-代数中定义了不分明化子代数和不分明化理想的概念,讨论了它们的性质及彼此间的关系。
the notion of bci implicative ideals is introduced. it is a natural generalization of the notion of implicative ideals in bck algebras.
