A New Approach of Complex Fuzzy Ideals in BCK/BCI-Algebras

open access: yesMathematics
The concept of complex fuzzy sets, where the unit disk of the complex plane acts as the codomain of the membership function, as an extension of fuzzy sets. The objective of this article is to use complex fuzzy sets in BCK/BCI-algebras.

Relationship between ideals of BCI-algebras and order ideals of its adjoint semigroup

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2001
We consider the relationship between ideals of a BCI-algebra and order ideals of its adjoint semigroup. We show that (1) if I is an ideal, then I=M−1(M(I)), (2) M(M−1(J)) is the order ideal generated by J∩R(X), (3) if X is a BCK-algebra, then J=M(M−1(J))

On pseudo-BCI-algebras

open access: yesAnnales Universitatis Mariae Curie-Sklodowska, sectio A – Mathematica, 2015
The notion of normal pseudo-BCI-algebras is studied and some characterizations of it are given. Extensions of pseudo-BCI-algebras are also considered.

Bivariate BCI Algebras

open access: yesInternational Journal of Mathematical Sciences and Optimization: Theory and Applications
 In this paper, the concept of bivariate BCI algebras is introduced. Properties of ρ- variate, λ variate and bivariate BCI algebras are investigated.
