摘要
主要研究了Schrdinger-KdV方程的保多辛结构的数值格式.首先讨论了它的正则方程组,然后对此方程组用多辛格式,例如中点格式离散.数值实验验证了格式的有效性.
The multisymplectic structure-preserving scheme for the Schrdinger-KdV equation was investigated.First the canonical formulation of the equation was discussed.Then,it was discretized by the multisymplectic integrator,such as a midpoint integrator.Numerical results were presented to illustrate the validity of the new scheme.
