Hyper logical algebras were first studied in 2000 by Borzooei et al. They applied the concept
of hyperstructures to one of the logical algebraic structures known as the BCK-algebra, and …

In this paper we introduced the notions of neutrosophic (strong, weak, s-weak) hyper BCK-
ideal and reflexive neutrosophic hyper BCK-ideal. Some relevant properties and their …

In this paper by considering the notion of hyper BCK-algebra, we state and prove some
theorems which determine the relationship among (weak) hyper BCK-ideals, positive …

In this note we define first the notions of positive implicative hyper K-ideals of types 1, 2,…, 8.
Then by giving many examples we show that these notions are different. After that we state …

The theory of hyper compositional structure has been introduced by F. Marty in 1934 during
the 8th congress of Scandinavian Mathematicians, where he presented his work [9]. Today …

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 …

In this note first we define the notions of positive implicative hyper BCK-ideals of types 1,
2,..., 8. Then, giving some examples, we show that these notions are different. After that we …

In this note first we define the notions of positive implicative hyper K-ideals of types 1, 2,...,
26, 27. Also we define the notions of commutative hyper K-ideals of types 1, 2,..., 8, 9. Then …

Algebraic hyperstructures represent a natural extension of classical algebraic structures and
they were introduced in 1934 by the French mathematician F. Marty [13] when Marty defined …
