چکیده مقاله:
The dominating sets play an important role in applications of graph theory. In this field, some recent studies discussed the properties of the minimum dominating set (\gamma -set). The other type of study produces a topological space from the set of vertices or the set of edges of a graph. The previous paper introduces a new method to construct a graph G_{\tau } from the topological space. In this paper, the dominating set and the domination number of G_{\tau } are proved with their inverse. The domination number and inverse domination number of corona operation and join operation between two graphs are discussed.
