Abstract: In this paper we introduce the notion of Bi-polar-valued Fuzzy hyper subalgebra (briefly BFHS)
of a Hyper BCI-algebra based on Bi-polar-valued fyzzy set and several related properties are also
established. Examples are also given to make the concept clear. Some characterization theorems of these
Bi-polar-valued Fuzzy hyper subalgebras are also derived. Further we considered the relationship among
these Bi-polar-valued Fuzzy hyper subalgebras by introducing strong positive t-cut and strong negative scut
of Bipolar valued fuzzy set of hyper BCI-algebra. Furthermore, we state Bi-polar-valued fuzzy
characteristic hyper subalgebra.
