一类非线性动力系统的孤立子波解

摘要/Abstract

摘要：

该文用泛函广义变分迭代方法，研究了一类非线性扰动动力系统.首先引入一个相应典型系统的孤立子波解.然后构造一组泛函广义变分式，求出Lagrange乘子，最后构造一组变分迭代关系式，由此便得到了原非线性扰动动力系统的渐近行波解.

Abstract:

Using the functional generalized variational iteration method, a class of nonlinear disturbed dynamic system was considered. First introduce solitary solution to a corresponding typical system. And then a set of functional generalized variation constructed, and Lagrange multiplier functions were solved. Finally, the generalized variational iteration was received. Thus, the asymptotic travelling wave solution to the original nonlinear disturbed generalized dynamic system was obtained
