摘要
针对无界区域上Korteweg.-de Vries(KdV)方程构造了时空全离散的ChebyshevHermite谱配置格式,即在空间方向上采用Hermite谱配置方法离散,时间方向上采用Chebyshev谱配置方法离散.提出了一个简单迭代算法,该算法非常适合并行计算.数值结果显示了此算法的有效性.
A Chebyshev-Hermite spectral collocation method is constructed for Korteweg-de Vries (KdV) equations on the whole line. The Hermite collocation method (based on the Lagrange interpolation) in space, and the Chebyshev-Gauss collocation method in time are used. A simple iterative algorithm is suggested, which can be implemented in a parallel fashion. Numerical results demonstrate the efficiency of the method.
