| Abstract: | Rough ideals in a semigroup has been studied and first been introduced the concepts of Rough subsemigroups and Rough ideals in \.In the paper,Rough subgroups and Rough normal subgroups in a Group are further considered. At the same time,the concepts of Rough subrings and Rough ideals in a ring are given;Finally,the homomorphism issues on Rough sets are discussed. |
