 [PDF]

潘阳, , 李德生
Advances in Applied Mathematics (AAM) , 2013, DOI: 10.12677/AAM.2013.23017
Abstract:

本文把离散的Lie点对称群分析方法应用于一个非线性微分–差分Toda晶格方程(即Toda-like晶格方程)。即首先应用Lie点对称方法约化Toda晶格方程,用以得到此方程对应的超定方程,再引入一个约化条件解超定方程,从而对该Toda晶格方程进行了相似约化,进而得到了其新的精确解。
In this paper, the discrete Lie point symmetry group analysis method is applied on a nonlinear dif- ferential-difference Toda lattice equation (i.e. a Toda-like equation), i.e. firstly, the Toda lattice equation is reduced by using Lie point symmetry to get the overdetermined equations corresponding to this Toda lattice equation, then a conditional symmetry is introduced to solve the overdetermined equations, so the similarity reduction for the Toda lattice equation is obtained, and then the new exact solutions of this Toda lattice equa- tion are obtained.

Advances in Applied Mathematics (AAM) , 2013, DOI: 10.12677/AAM.2013.24021
Abstract:
本文主要研究了藕合的二阶AKNS方程的可积离散化。首先对藕合的二阶AKNS方程的半离散双线性导数方程运用Hirota方法和Maple求出了其新的N-孤子解;然后通过对半离散的双线性导数方程中的时间变量进行离散化,得到全离散的双线性导数方程并对其进行了求解;最后通过适当的变换得出差分差分AKNS方程。
>This paper mainly studied the integrable discretization of the second order coupled AKNS equation. First of all, some new N soliton solutions of the semi-discrete double linear derivative equation of the second order coupled AKNS equation are got by using the Hirota method and Maple. Then, the full discrete bilinear derivative equation is obtained through the method of discrete time of the semi-discrete double linear deriva- tive equation and its N soliton solutions are found out. Finally, the difference-difference AKNS equation is obtained by an appropriate transformation.
