Certain Properties of Bipolar Fuzzy Soft Topology Via Q-Neighborhood

Abstract

In the present work, we bring out some properties of bipolar fuzzy soft topology (BFS-topology) by using the concept of Q-neighborhood. Firstly, we define the concept of quasi-coincident and Q-neighborhood for BFS-point and BFS-set, then we discuss certain properties of BFStopology including, BFS-accumulation point, BFS-dense subset, BFScountability axioms and BFS-separable space by utilizing BFS Q-neighborhood. We also study the concept of BFS-Lindelo¨f space. Furthermore, we apply the concept of BFS quasi-coincident in decision-making of a real world problem by using BFS-AND, BFS-OR operations
