More general forms of generalized fuzzy bi-ideals in semigroups

More general forms of the paper by O. Kazanci and S. Yamak (General- ized fuzzy bi-ideals of semigroups, Soft Comput. 12, 1119–1124, 2008) are discussed. The notion of (∈,∈∨ qk)-fuzzy bi-ideals in a semigroup S is introduced, and several properties are investigated. Characteriza- tions of an (∈,∈∨ qk)-fuzzy bi-ideal in a semigroup S are discussed.
