multisymplectic structure and multisymplectic Scheme for the Nonlinear Ware Equation
收藏 引用
Acta Mathematicae Applicatae Sinica 2002年 第1期18卷 169-176页
作者: Yu-shun WANG, Meng-zhao QINLASG, Institute of Atmospheric Physics, Chinese Academy of Sciences, Beijing 100029, ChinaInstitute of Computational Mathematics, Academy of Mathematics and System Sciences, Chinese Academy of Sciences, Beijing 100080, China LASG Institute of Atmospheric Physics Chinese Academy of Sciences Beijing China Institute of Computational Mathematics Academy of Mathematics and System Sciences Chinese Academy of Sciences Beijing China
The multisymplectic structure of the nonlinear wave equation is derived directly from the variational principle. In the numerical aspect, we present a multisymplectic nine points scheme which is equivalent to the mult... 详细信息
