Abstract
The concepts of ()-fuzzy bi-hyperideals and ()-fuzzy quasi-hyperideals of a semihyperring are introduced, and some related properties of such ()-fuzzy hyperideals are investigated. In particular, the notions of hyperregular semihyperrings
and left duo semihyperrings are given, and their characterizations in terms of hyperideals and ()-fuzzy hyperideals are studied.
