Abstract	Let G be a graph on n vertices and λ1, λ2, . . . , λn its eigenvalues. The Estrada index of G is defined as EE(G) = ∑n i=1 e λi . In this work, using a different demonstration technique, new lower bounds are obtained for the Estrada index, that depends on the number of vertices, the number of edges and the energy of the graph is given. Moreover, another lower bound for the Estrada index is obtained of an arbitrary Hermitian matrix are established.
