The concept of energy of a graph was first defined in 1978 by Gutman as the sum of the absolute values of the eigenvalues of its adjacency matrix. Let lambda(1), lambda(2), ..., lambda(n) be eigenvalues of graph Gamma, then the Estrada index of Gamma is defined as EE(Gamma) = Sigma(n)(i=1) e(lambda i). The aim of this paper is to estimate the energy and Estrada index of Cayley graphs Cay(G, S) where G congruent to D-2n, U-6n and S is a normal symmetric generating subset of G. |
