Fuzzy BCI-subalgebras with interval-valued membership functions
International Journal of Mathematics and Mathematical Sciences, 2001 The purpose of this paper is to define the notion of an interval-valued fuzzy BCI-subalgebra (briefly, an i-v fuzzy BCI-subalgebra) of a BCI-algebra. Necessary and sufficient conditions for an i-v fuzzy set to be an i-v fuzzy BCI-subalgebra are stated. A

Hybrid Structures Applied to Ideals in BCI-Algebras
Journal of Mathematics, 2020 In this paper, the notion of hybrid structure is applied to the ideal theory in BCI-algebras. In fact, we introduce the notions of hybrid p-ideal, hybrid h-ideal, and hybrid a-ideal in BCI-algebras and investigate their related properties.

MBJ-neutrosophic hyper BCK-ideals in hyper BCK-algebras
AIMS Mathematics, 2021 In 2018, Takallo et al. introduced the concept of an MBJ-neutrosophic structure, which is a generalization of a neutrosophic structure, and applied it to a BCK/BCI-algebra.

T‐fuzzy ideals in BCI‐algebras [PDF]
International Journal of Mathematics and Mathematical Sciences, 2005 Using a t‐norm T, we introduce the notions of T‐fuzzy subalgebras and T‐fuzzy H‐ideals in BCI‐algebras and investigate some of their properties.

On f-derivations of BCI-algebras
International Journal of Mathematics and Mathematical Sciences, 2005 The notion of left-right (resp., right-left) f-derivation of a BCI-algebra is introduced, and some related properties are investigated. Using the idea of regular f-derivation, we give characterizations of a p-semisimple BCI-algerba.

An ordered structure of pseudo-BCI-algebras [PDF]
Mathematica Bohemica, 2016 To any pseudo-BCI-algebra [the reviewer and \textit{Y. B. Jun}, East Asian Math. J. 24, No. 2, 187--190 (2008; Zbl 1149.06010)], two binary operations (each of them being similar to that of a directoid) and a set of couples of antitone mappings is assigned which are in a certain sense mutually inverse.

On the generalization of pseudo p-closure in pseudo BCI-algebras [PDF]
Journal of HyperstructuresIn this paper, the notion of generalization of pseudo p-closure, denoted by gcl, is introduced and its related properties are investigated. The gcl of subalgebras and pseudo-ideals is discussed.

Multipolar Intuitionistic Fuzzy Set with Finite Degree and Its Application in BCK/BCI-Algebras
Mathematics, 2020 When events occur in everyday life, it is sometimes advantageous to approach them in two directions to find a solution for them. As a mathematical tool to handle these things, we can consider the intuitionistic fuzzy set. However, when events are complex

Łukasiewicz anti fuzzy subalgebras of BCK/BCI-algebras [PDF]
The subalgebra of BCK/BCI-algebra using Łukasiewicz anti fuzzy set introduced by Jun is studied in this article. The concept of Łukasiewicz anti fuzzy subalgebra of a BCK/BCI-algebra is introduced, and several properties are investigated.
