Fuzzy ?-ideals in ?-AG-groupoids

Fuzzy ?-ideals in ?-AG-groupoids

In this paper we study fuzzy ?-ideals and prime, semiprime fuzzy ?ideals of a ?-AG-groupoid S. We prove that, if S is a ?-AG-groupoidwith left identity, then every fuzzy ?-ideal of S is idempotent if andonly if every fuzzy ?-ideal of S is semiprime. We also show that, if Sis a ?-AG-groupoid with left identity e, then every fuzzy ?-ideal of Sis prime if and only if every fuzzy ?-ideal of S is idempotent and theset of fuzzy ?-ideals of S is totally ordered by inclusion.
