Abstract
In the present paper, we introduce the notions of (1, 2)*-fuzzy soft b-separated sets, (1, 2)*-fuzzy soft b-connectedness and (1, 2)*-fuzzy soft b-compactness in fuzzy soft bitopological spaces. Then, some basic topological properties of these notions are investigated. Also, some illustrative examples are given to show the importance of the obtained theorems.
