Abstract
In covering setting, there are five types of rough set models in literature, but only one type of them has been studied from the point of topological view. In this paper, we address the topological properties in the other four types of covering-based rough sets; especially we present the conditions under which lower approximation operations become interior operators and the conditions under which the upper approximation operations become closure operators.
