Topological properties of generalized rough sets
LI Zhao-wen · 2010 Seventh International Conference on Fuzzy Systems and Knowledge Discovery · 2010
In this paper, we introduce the concept of θs, which is the transmissing expression of a reflexive relation θ on domain X, study the topological properties of generalized rough set (X, θ) and get some interesting results. These results will be not only conducive to better understanding of some basic concepts and properties in rough set theory, but also have theory and actual significance to topology.
