Group Analysis and New Explicit Solutions of Simplified Modified Kawahara Equation with Variable Coefficients

The simplified modified Kawahara equation with variable coefficients is studied by using Lie symmetry method. Then we obtain the corresponding Lie algebra, optimal system, and the similarity reductions. At last, we also give some new explicit solutions fo

利用李对称方法研究了变系数的简化修正的Kawahara方程。然后我们得到了相应的李代数、最优系统以及相似约化。最后，我们还给出了一些新的显式解。
