| 摘 要： | Nonlinear Schroedinger equation arises in many physical problems. There are many works in which properties of the solution are studied. In this paper we use fully discrete Fourier spectral method to get an approximation solution of nonlinear weakly dissipative Schroedinger equation with quintic term. We give a large-time error estimate and obtain the existence of the approximate attractor A N^k.

In this paper we use fully discrete Fourier spectral method to get an approximation solution of nonlinear weakly dissipative Schrodinger equation with quintic term. We give a large-time error estimate and obtain the existence of the approximate at-tractor ANk. |
