MKdV方程的多辛格式

Multi-Symplectic Scheme for MKdV Equation

提出了MKdV方程的一个多辛Hamilton形式,并利用中点辛离散得到一个等价于多辛Preissman积分的新格式,最后用数值例子说明:多辛格式具有良好的长时间数值行为.

We present a multi-symplectic Hamiltonian formulation for MKdV equation,and get a new scheme which is equivalent to the multi-symplectic Preissman integrator by discreting the equations with middle point formulations.And the numerical experiments show that the multi-symplectic scheme has excellent long-time numerical behavior .
