Abstract
Davvaz (2008) introduced the concept of set-valued homomorphism and -rough sets in a group. In this paper, we consider the set-valued homomorphism on -semihypergroup to interpret the lower and upper approximations. We study the roughness of bi--hyperideals and quasi--hyperideals in terms of set-valued homomorphisms, which are extended notions of bi--hyperideals and quasi--hyperideals of -semihypergroups.
