• WIENER INDEX AND WIENER POLYNOMIAL FOR SOME SPECIAL GRAPHS
Abstract
The Wiener Index is a graphical invariant that has found extensive application in all branches of science. It is a distance based topological index defined as the sum of the distance between all pairs of vertices in a graph. A generating function, which we call Wiener polynomial is also defined. In this paper, Wiener index and Wiener polynomial of Wheel graph, Friendship graph and Barbell graph are obtained.
