This paper aims to introduce new notions of (fuzzy) n-fold P-ideals and (fuzzy) n-fold weak P-ideals in BCI-algebras, and investigate several properties of the foldness theory of P-ideals in BCI-algebras. Finally, we ...

The notions of norm and distance in BCI-algebras are introduced, and some basic properties in normed BCI-algebras are given. It is obtained that the isomorphic(homomorphic) image and inverse image of a normed BCI-alge...
The BCK/BCI/BCH-algebras finds general algebra system than Boolean algebras system. This paper presents a novel class of algebras of type (2, 0) called BCL-algebras. We found the BCL-algebras to be more extensive clas...
Some properties about stable subset S(θ n) and image Im(θ n) of self homomorphism \{θ n:x→0*x n\} are discussed. The characterization that Im(θ n) becomes an ideal of BCI algebra X is given.
Some properties of nil ideals in BCI-algebras are discussed. The notion of k-associative BCI-algebras which is a generalization of associative and quasi-associative BCI-algebras is introduced. Moreover,several charact...
In 1966, Imai, Y. and the latter author of this paper introduced the BCK-algebra in the following Definition 1. Let X be a set with a binary operation * and a constant 0. Then X is called a BCK-algebra, if it satisfie...
