摘要:

讨论等谱与非等谱Burgers方程族的精确解.两个方程族都可以通过Cole-Hopf变换化为线性形式,利用Wronskian方法中Wronskian元素的构造技巧给出若干不同形式的精确解,研究这些解之间的关系及动力学特征.

关键词:  Burgers方程族;精确解;动力学特征

Abstract:

We consider exact solutions for the isospectral and nonisospectral Burgers hierarchies. The two hierarchies can be linearized through the ColeHopf transformation. Solutions are given using the technique for selecting Wronskian entries. Relationship between some solutions and their dynamic characteristics are investigated.

Key words: Burgers equation hierarchies; exact solutions; dynamic characteristics
