valued fuzzy set. By using this new idea, we introduce the notions of interval valued (∈, ∈\!
∨\, q)-fuzzy filters of pseudo BL-algebras and investigate some of their related properties.
Some characterization theorems of these generalized interval valued fuzzy filters are
derived. The relationship among these generalized interval valued fuzzy filters of pseudo BL-
algebras is considered. Finally, we consider the concept of implication-based interval valued …
