Binary Bipolar Soft Sets

In this paper, we give on interesting connection between two mathematical approaches to vagueness: bipolar soft sets and binary soft sets. The nation of binary bipolar soft set over two universal sets and a parameter set is proposed. The complement, union, intersection, restricted union, restricted intersection, null binary bipolar soft set, absolute binary bipolar soft set, difference of two binary bipolar soft sets, "AND ", "OR " operations are defined on the binary bipolar soft sets. The basic properties of binary bipolar soft sets are also investigated and discussed. Finally we give a characteristic function of binary bipolar soft set.
