Abstract
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 C θ
12 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.
