Let G be a finite simple undirected graph with n vertices and m edges. The Harmonic energy of a graph G, denoted by HE(G), is defined as the sum of the absolute values of all Harmonic eigenvalues of G. The Harmonic Estrada index of a graph G, denoted by HEE(G), is defined as HEE = HEE(G) =∑Pn i=1 ei , where 1 > 2 > · · · > n are the H-eigenvalues of G. In this paper we present some new bounds for HE(G) and HEE(G) in terms of number of vertices, number of edges and the sum-connectivity index. |
