Approximae solution for a class of the disturbed evolution equation

摘要: 采用了一个简单而有效的技巧,研究了一类扰动发展方程.首先引入求解一个相应典型方程的行波孤波解.然后利用渐近方法得到了原扰动发展方程的近似解.利用泛函分析的不动点定理,指出了近似解级数的收敛性,并讨论了近似解的精度.

Abstract: A class of disturbed evolution equation is considered by a simple and valid technique.We first introduce the traveling solitary wave solution of a corresponding typical differential equation,and then use the asymptotic method to obtain the approximate solution for an original disturbed evolution equation.And we point out that the series of approximate solution is convergent and the precision of the approximate solution is discussed by using the fixed point theorem for the functional analysis.
