More on Continuity in Rough Set Theory

Annual Meeting in Mathematics 2023

Abstract

It is generally known that in rough set theory, we can define the topology imposed by the lower approximation operator in the approximation space (U, R). As a result, any approximation can be viewed as a topological space. In this article, we present the sufficient condition for a map between two approximation spaces to be a continuous map. Some elementary properties of the maps are stated.
