In this paper, exact solutions for a class of nonlinear Schr?dinger equation with wave operator are studied. The Jacobi elliptic function and the hyperbolic function combination method are involved in order to obtain the exact solutions.Many new solutions of the nonlinear Schr?dinger equation with wave operator are obtained by the simple algebraic operation and the corresponding hyperbolic function solution of equation in the limit case. Meanwhile, the conclusion is drawn that combination solutions of the h...
