Abstract :
In this paper, we introduce the concepts of ðr; sÞ-fuzzy F-open and ðr; sÞ-fuzzy F-closed sets
in double fuzzy topological spaces. We used them to explain the notions of ðr; sÞ-fuzzy Fclosed
spaces. Also, we give some characterization of ðr; sÞ-fuzzy F-closeness in terms of
fuzzy filterbasis.
