标题： Equivalence groupoid and enhanced group classification of a class of generalized Kawahara equations

摘要： 广义Kawahara方程类在时间依赖系数下的变换性质被研究。 我们构造了该类的等价胚体，并证明该类不是规范化的，但可以表示为两个不相交的规范化子类的并集。 利用获得的结果并适当规约该类的任意元素，我们进行了其完整的群分类，这弥补了该主题先前研究中的不足。 显示英文摘要

摘要： Transformation properties of a class of generalized Kawahara equations with time-dependent coefficients are studied. We construct the equivalence groupoid of the class and prove that this class is not normalized but can be presented as a union of two disjoint normalized subclasses. Using the obtained results and properly gauging the arbitrary elements of the class, we carry out its complete group classification, which covers gaps in the previous works on the subject.
