| Abstract: | This paper proposes the new notions,namely,upper approximate equality,lower approximate equality,of mdiscernibility relation are defined by studying mdiscernibility,in Rough sets.Also which study upper opproximate distance and lower approximate distance between different indiscernibility relations in the paper the properties of them have been also studied preliminarily. |
