| Abstract: | Based on the variable precision rough set model and the notions of the rough left ideal,rough right ideal,rough two.sided ideal and rough bi-ideal in a semigroups,this article disscuss some properties of rough ideal and the product of two ideals in a semigroup.Thus it enrich the rough theory in semigroups. |
