摘要/Abstract

摘要：

该文研究了广义超弹性杆波方程.利用行波变换将广义超弹性杆波方程转化为一个复微分方程，并通过弱$\left\langle {h, k} \right\rangle $条件和Fuchs指数证明了该复微分方程的亚纯解属于W类.进一步求出了该复微分方程的所有亚纯解，从而得到了广义超弹性杆波方程的行波解.可将该文的方法应用到一些相关的数学物理方程.

关键词: 广义超弹性杆波方程, 微分方程, 椭圆函数, 亚纯函数

Abstract:

In this paper, we study the generalized hyperelastic-rod wave equation. We changed the generalized hyperelastic-rod wave equation into a complex differential equation by using traveling wave transform and show that meromorphic solutions of the complex differential equation belong to the class W by the weak $ \left\langle {h, k} \right\rangle $ condition and the Fuchs index. Furthermore, we find out all meromorphic solutions of the complex differential equation, then we obtain the traveling wave solutions of the generalized hyperelastic-rod wave equation. We can apply the idea of this study to some related mathematical physics equations.

Key words: Generalized hyperelastic-rod wave equation, Differential equation, Elliptic function, Meromorphic function
