摘要
考虑非线性MkdV方程的多辛形式,对于多辛形式,提出了一个等价于中心Preissman积分的15点多辛格式.数值试验给出了MkdV方程单孤子和双孤子解时间演化的数值模拟.结果表明:多辛格式具有良好的长时间数值行为.
The multi-symplectic formulation of the MKdV equation is considered. For the multi-symplectic formulation , a fifteen-point difference scheme which is equivalent to the multi-symplectic Preissman integrator is derived. The numerical experiments show that the multi-symplectic scheme has excellent long- time numerical behavior .
