New multi-order envelope periodic solutions to cubic nonlinear Schr dinger equation
Based on the Lamé equation and Lamé functions, the perturbation method and Jacobi elliptic function expansion method are applied to construct the multi-order exact solutions to the cubic nonlinear Schr?dinger equation. Some new multi-order envelope periodic solutions are found among the nonlinear evolution equations. These multi-order envelope periodic solutions correspond to different periodic solutions, which can degenerate into the different envelope solitary solutions. It is shown that some multi-order asymptotic periodic solutions to some nonlinear evolution equations in term of Jacobi elliptic functions and Lamé equation are explicitly obtained with the aid of symbolic computation.
