%X Let be a simple graph with vertices. Let , where and and denote the adjacency matrix and degree matrix of , respectively. is called the -Estrada index of , where denote the eigenvalues of . In this paper, the upper and lower bounds for are given. Moreover, some relations between the -Estrada index and -energy are established
