In this present work, a novel category of fuzzy sets termed double fuzzy SWT-open sets is developed and studied, and its connections to earlier ideas are probed at. Some theorems and assertions are used illustrate the properties of this new class of double fuzzy sets. In addition, a stronger types of double fuzzy SWT-open sets are presented. Finally, we contest and characterize a double fuzzy generalized SWT-closed as applications to fuzzy SWT-closed.
