Also, fuzzy S-ideals, fuzzy k-ideals and fuzzy P-ideals of a KU-semigroup are studied and few important properties are obtained. Furthermore, few results of fuzzy S-ideals of a KU-semigroup under homomorphism are discussed. Keywords: KU-algebra;KU-semigroup;fuzzy S-ideal;fuzzy k-ideals;fuzzy P-ideas;Iraq
