摘要
提出了一种新的辅助方程方法来探究非线性演化方程的精确解,这种方法由含有十阶非线项常微分方程构造而成。运用这种方法,得到非线性Sharma-Tasso-Olver方程的一些新的孤立波解和三角周期波解。
A new extended auxiliary equation method, constructed by a first order nonlinear ordinary differential equation with a tenth-degree nonlinear term, is proposed for exploring new exact solutions for nonlinear evolution equations. The method is applied to the Sharma-Tasso-Olver model, and some new exact solutions are obtained which include solitary wave solutions and triangular periodic wave solutions.
