Ω-INTERVAL-VALUED FUZZY SUBSEMIGROUPS IN A SEMIGROUP Lee, Jeong Gon; Hur, Kul; Lim, Pyung Ki;
By using a set , we introduce the concept of -fuzzy subsemigroups and study some of it's properties. Also, we show that the homomorphic images and preimages of -fuzzy subsemigroups become -fuzzy subsemigroups.
