Abstract

In this paper we modify the result in [2], discuss the lattice property of fuzzy rough sets and introduce lattice isomorphism from the equivalence class of fuzzy rough sets to intuitionistic fuzzy sets. The result of this paper extends the corresponding conclusion in [2] and will be applied in the area of computer science.
