摘要:

本文考虑了一族变系数五阶KdV方程。通过基于等价群确定的无穷小方法,获得了微分不变量和不变方程。不变量提供了一种替代途径,用于从该族中找出可能等价于同一族特定子类的方程,以及映射两个等价方程的可逆变换。在此,微分不变量被应用于获得精确解。

英文摘要:

In this paper, a family of variable-coefficient fifth-order KdV equations has been considered. By using an infinitesimal method based on the determination of the equivalence group, differential invariants and invariant equations are obtained. Invariants provide an alternative way to find equations from the family which may be equivalent to a specific subclass of the same family and the invertible transformation which maps both equivalent equations. Here, differential invariants are applied to obtain exact solutions.
