KP方程的多辛几何与多辛Preissman格式

Multisymplectic Geometry and Multisymplectic Preissman Scheme for the KP Equation

Tingting Liu, Menzhao Qin

摘要:

从变分原理出发,直接得到KP方程的多辛结构。利用协变的De Donder-Weyl Hamilton函数理论,将KP方程转化为Bridges提出的多辛形式。从多辛方程出发,导出KP方程的一个多辛数值格式,该格式可简化为多辛45点格式。

英文摘要:

The multisymplectic structure of the KP equation is obtained directly from the variational principal. Using the covariant De Donder-Weyl Hamilton function theories, we reformulate the KP equation to the multisymplectic form which proposed by Bridges. From the multisymplectic equation, we can derive a multisymplectic numerical scheme of the KP equation which can be simplified to multisymplectic forty-five points scheme.
