广义对称正则长波方程的傅里叶拟谱方法

The Fourier pseudospectral methods for the generalized symmetric regularized long wave equations

用拟谱方法讨论了一类广义对称正则长波方程的周期初值问题。构造了半离散和全离散的Fourier拟谱格式 。

Fourier pseudospectral methods for the generalized symmetric regularized long wave equations are presented. The semi discrete and fully discrete pseudospectral schemes are constructed, Convergence with semi discrete and fully discrete pseudospectral accuracy is proved and the optimum error estimation obtained.
