摘要
研究了一类新的可积型浅水波方程即Dullin-Gottwald-Holm(DGH)方程的反散射逼近问题.通过一种逼近法为DGH方程的反散射问题提供了一种新的计算上更为简单的算法,即将初始位势的计算转化为求解一个线性积分方程和一个反函数;最后以具体例题演示了此算法,完善了DGH方程的反散射问题.
Inverse scattering approach was studied for a new integrable shallow water wave equation named Dullin-Gottwald-Holm equation(i.e.DGH equation).An alternative approach,which provided a more convenient algorithm for inverse scattering problem,was proposed.In this algorithm,the initial potential was amounted by solving a linear integrable equation and an inverse function.Some computing examples show the applicability of the new approaches.
