Relations between energy of graphs and wener, harary indices

Harary and Wiener indices are distance-based topological index. In this paper, we study the relations of graph energy \varepsilon(G) and its Harary index \textup{H}(G) and Wiener index \textup{W}(G). Moreover, for a given graph G we study the lower bound of \frac{\textup{H}(G)}{\varepsilon(G)} and \frac{\textup{W}(G)}{\varepsilon(G)} in terms of number of vertices of G.
