摘要

我们研究了描述许多非线性现象的扩展六阶 Korteweg-de Vries（KdV6）方程。研究采用了改进的修正（IM）扩展 tanh 函数方法。得到了许多精确解，如暗解、组合奇异-暗解和奇异孤子解。此外，还推导出了双曲解、奇异周期解、有理解、指数解和雅可比椭圆函数（JEF）解。图解直观地描述了选定解的动态。

Diverse exact and solitary wave solutions to new extended KdV6 equation using IM extended tanh-function technique

We investigated the extended sixth-order Korteweg–de Vries (KdV6) equation which describes many nonlinear phenomena. The improved modified (IM) extended tanh-function method is used to conduct the study. Many exact solutions, like dark, combo singular-dark and singular soliton are achieved. Moreover, hyperbolic solutions, singular periodic solutions, rational solutions, exponential solutions and Jacobi elliptic function (JEF) solutions are derived. Graphical illustrations are presented to visually depict the dynamics of selected solutions.
