BIPOLAR FUZZY HYPER BCK-IDEALS IN HYPER BCK-ALGEBRAS

2011
Using the notion of bipolar-valued fuzzy sets, the concepts of bipo- lar fuzzy (weak, -weak, strong) hyper BCK-ideals are introduced, and their relations are discussed. Moreover, several related properties are investigated.

Hyper BCK-ideals based on soft set theory

Asian-European Journal of Mathematics, 2016
The notions of int-soft hyper [Formula: see text]-ideals, int-soft strong hyper [Formula: see text]-ideals, int-soft [Formula: see text]-weak hyper [Formula: see text]-ideals, int-soft weak hyper [Formula: see text]-ideals and int-soft reflexive hyper [Formula: see text]-ideals are introduced, and related properties and relations are investigated ...

INTUITIONISTIC FUZZY HYPER BCK-IDEALS OF HYPER BCK-ALGEBRAS

2004
The intuitionistic fuzzification of (strong, weak, s-weak) hyper BCK-ideals is introduced, and related properties are investigated. Character- izations of an intuitionistic fuzzy hyper BCK-ideal are established. Using a collection of hyper BCK-ideals with some conditions, an intuitionistic fuzzy hyper BCK-ideal is built.

FUZZY (POSITIVE, WEAK) IMPLICATIVE HYPER BCK-IDEALS

2004
In this note first we define the notions of fuzzy positive implicative hyper BCK-ideals of types 1,2,3 and 4. Then we prove some theorems which characterize the above notions according to the level subsets. Also we obtain the relationships among these notions, fuzzy (strong, weak, reflexive) hyper BCK-ideals and fuzzy positive implicative hyper BCK ...
