Erratum to “Study on quasi-Γ-hyperideals in Γ-semihypergroups”
We wrote this note to show that the definition of Γ-hypersemigroups in [2] should be corrected, and thatit is not enough to replace the hyperoperation ◦ of the hypersemigroup by Γ to pass from a hypersemigroup to aΓ-hypersemigroup. Care should be taken about the definitions of (m, n)-quasi-Γ-hyperideal, the m-left Γ-hyperidealand the n-right Γ-hyperideal as well.
