Neutrosophic Hyper BCK-Ideals

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 relations are indicated.
Characterization of neutrosophic (weak) hyper BCK-ideal is considered. Conditions for a neutrosophic set
to be a (reflexive) neutrosophic hyper BCK-ideal and a neutrosophic strong hyper BCK-ideal are discussed.
Also, conditions for a neutrosophic weak hyper BCK-ideal to be a neutrosophic s-weak hyper BCK-ideal,
and conditions for a neutrosophic strong hyper BCK-ideal to be a reflexive neutrosophic hyper BCK-ideal
are provided.
