Rough Set Theory Applied To Hyper BCK-Algebra

open access: yesRatio Mathematica, 2014
The aim of this paper is to introduce the notions of lower and upper approximation of a subset of a hyper BCK-algebra with respect to a hyper BCK-ideal. We give the notion of rough hyper subalgebra and rough hyper BCK-ideal, too, and we investigate their

Bipolar Fuzzy Commutative Hyper BCK-ideals in Hyper BCK-algebras

open access: yesEuropean Journal of Pure and Applied Mathematics
This study introduces the concept of bipolar fuzzy commutative hyper BCK-ideals (BF-CHBCKIs) within the algebraic framework of hyper BCK-algebras, offering a novel approach to modeling dual uncertainty through bipolar fuzzy sets. By defining and classifying BF-CHBCKIs across multiple types and examining their structural relationships with reflexive ...

(Weak) implicative hyper BCK-ideals

open access: yes, 2004
Summary: We first define the notion of weak implicative hyper BCK-ideal of a hyper BCK-algebra. Then we state and prove some theorems which determine the relationship among this notion and (weak, commutative, (strong) implicative) hyper BCK-ideals, positive implicative hyper BCK-ideals of type \(1,3,\dots,8\) and (strong) positive implicative hyper BCK-

Positive Implicative Hyper BCK-Ideals of Hyper BCK-Algebras Under an Interval-Valued Intuitionistic Fuzzy Environment

open access: yesInternational Journal of Analysis and Applications
This paper contains some new theorems related to hyper BCK-ideals positive implicative hyper BCK-ideals of types-1, 2, 3, 4 of hyper BCK-algebras (HBCKA) under an interval-valued intuitionistic fuzzy environment. Henceforth, the connection between these ideas and their relevant characteristics is discussed.
