Abstract :
The purpose of this paper is to introduce the concept of pairwise F-closedness in
bitopological spaces. This space contains both of pairwise strong compactness and pairwise S- closedness and contained in pairwise quasi H-closedness. The characteristics and relationships concerning this new class of spaces with other corresponding types are established. Moreover, several of its basic and important properties are discussed.
