A Note on Characterization of Regular Γ-Semigroups in terms of (∈,∈ ∨q)-Fuzzy Bi-ideal Year: 2011 Volume: 5 Issue: 4 617 - 620 Pages Authors: S.K.Sardar B.Davvaz S.Kayal S.K.Majumdar Abstract: The purpose of this note is to obtain some properties of (∈,∈ ∨q)- fuzzy bi-ideals in a Γ-semigroup in order to characterize regular and intra-regular Γ-semigroups. Keywords: Regular Γ-semigroup belong to or quasi-coincident (∈ ∈ ∨q)-fuzzy subsemigroup (∈ ∈ ∨q)-fuzzy bi-ideals.
