In this paper, we introduce the notion of (r, s)-(i, j)-θ-generalized double fuzzy closed sets in double fuzzy bitopological spaces. A new θ-double fuzzy closure C12θ on double fuzzy bitopological spaces by using double supra fuzzy topological spaces are defined. Furthermore, generalized double fuzzy θ-continuous (resp. irresolute) and double fuzzy strongly θ-continuous mappings are introduced and some of their properties studied.
