TWO NOTES ON ROUGH NELSON ALGEBRAS AND ROUGH FUZZY SETS

摘要：

Two issues on rough sets are discussed in this paper. Firstly, a mistake on rough Nelson algebra is pointed out, and generalized rough Nelson algebra is introduced. Secondly, the following result is proved: the rough fuzzy set model is a special case of the generalized rough set based on covering over De Morgan algebra.
