本文研究一类双非线性色散方程——Sharma-Tasso-Olver方程。采用扩展双曲函数方法研究了该方程中的孤立行波和周期行波。借助于数学软件和五元消元法,导出了非线性Sharma-Tasso-Olver方程的大量精确显式解。本文得到的解包括(a)孤波解,(b)奇异行波解,(c)三角函数型的周期行波解。除了用系统的方法推导出所有已知的解外,还显式地得到了该方程的几个全新的精确解。这项工作可以看作是Wazwaz最近工作的延伸。
This paper is concerned with a double nonlinear dispersive equation—the Sharma–Tasso–Olver equation. The extended hyperbolic function method is employed to investigate the solitary and periodic travelling waves in this equation. With the aid of Mathematica and Wu-elimination Method, the abundant exact explicit solutions of the nonlinear Sharma–Tasso–Olver equation are derived. The solutions obtained in this paper include (a) solitary wave solutions, (b) the singular travelling wave solutions, and (c) periodic travelling wave solutions of triangle function types. Several entirely new exact solutions to the equation are explicitly obtained, in addition to deriving all known solutions in a systematic way. This work can be regard as an extension to the recent work by Wazwaz.
