Özet: Let G be a graph with n vertices and di is the degree of its i-th vertex( di is the degree of vi), then the Harmonic matrix of G is the square matrix of order n whose (i; j)-entry is equal to 2 di+dj if the i-th and j-th vertex of G are adjacent, and zero otherwise. The main purposes of this paper are to introduce the Harmonic Estrada index of a graph. In addition we establish upper and lower bounds for these energy and index separately also we investigate the relations between the Harmonic Estrada index and the Harmonic energy.
