In this paper, a unified approach to the notion of D-sets in topological
spaces is given. In fact new types of D-sets can be defined by replacing
“open set” by a topological set. According to Tong, each pair (U,V) of
open sets with U?X, contributes a D-set . Our aim is to introduce new
types of D-sets by replacing either U or V by another type of topological
sets namely ?-open, pre-open, semi-open, ?-open, ?-open, b-open pre-?-
open, semi-?-open, ?-?-open, ?-?-open and b-?-open sets
