Abstract (2. Language): 
The aim is to show that the theory of hypersemigroups and the theory of fuzzy hyper- semigroups are parallel to each other, in the following sense: An hypersemigroup H is intra-regular, for example, if and only if A\B  BA for every right ideal A and every left ideal B of H. And an hypersemigroup H is intra-regular if and only if f ^g  g f for every fuzzy right ideal f and every fuzzy left ideal g of H. An hypersemigroup H is left quasi-regular if and only if A\B  AB for every ideal A and every nonempty subset B of H. And an hypersemigroup H is left quasi-regular if and only if f ^ g  f  g for every fuzzy ideal f and every fuzzy subset g of H.
