Bipolar-valued fuzzification of the notion of implicative hyper BCK-ideals
is considered. Using the concepts of positive and negative lever sets, a characterization
of a bipolar fuzzy implicative hyper BCK-ideal is provided. A relation between a
bipolar fuzzy hyper BCK-ideal and a bipolar fuzzy implicative hyper BCK-ideal is
established. A condition for a bipolar fuzzy hyper BCK-ideal to be a bipolar fuzzy
implicative hyper BCK-ideal is given. By using a collection of implicative hyper
BCK-ideals, a bipolar fuzzy implicative hyper BCK-ideal is established.
