寻求2n+1阶KdV孤立子方程的符号计算方法

Symbolic Computation Method of Finding (2n+1)-order KdV Equations

将符号计算方法和守恒密度计算软件相结合 ,得到了具有足够多守恒律的 9阶、11阶KdV方程 ,从而得出确定 2n + 1阶KdV方程具有一致阶时的系数之间关系式的一种方法 .

Applying symbolic computation methods integrated with conserved densities computation software, this paper gets the 9_order KdV equations and 11_order KdV equations which have enough conservation law. It can deduce the method of finding the coefficients relation of (2 n +1)_order KdV equations which have the same rank.
