Interval valued (is an element of, is an element of boolean OR q)-fuzzy ideals of pseudo-MV algebras
In this paper, we first introduce the concept of quasi-coincidence of a fuzzy interval value with an interval valued fuzzy set. By using this new idea, we consider the interval valued (is an element of,is an element of boolean OR q)-fuzzy (implicative) ideals of pseudo-MV algebras and investigate some of their related properties. Some characterization theorems of these generalized fuzzy (implicative) ideals are derived.
