本文考虑Sharma-Tasso-Olver(STO)方程的级数解.利用推广的齐次平衡法,将STO方程化为线性偏微分方程,得到了线性偏微分方程的Bäcklund变换,进而得到了STO方程解的自变换.通过Bäcklund变换和偏微分方程的各种级数解,得到了STO方程的丰富的精确解,包括多孤波解、三角函数级数解、有理级数解以及由这三类解组成的解.
This paper considers series solutions of the Sharma–Tasso–Olver (STO) equation. By using the extended homogenous balance method, we reduce the STO equation to a linear PDE and obtain Bäcklund transformation of it. Furthermore, the self-transformation of solutions for the STO equation is obtained. By the Bäcklund transformation and various series solutions of the PDE, abundant exact solutions of the STO equation are obtained including the multi-solitary wave solution, trigonometric function series solution, rational series solution and solution consisting of the three types of solutions.
