Abel微分方程可积性的几何方法

A geometric approach to integrability of Abel differential equations

José F. Cariñena, Javier de Lucas, Manuel F. Rañada

摘要:

用几何方法研究了一类Abel型一阶微分方程。该方法是基于最近发展的准李系统的理论,使我们能够解释一些特殊的例子可积阿贝尔方程。二阶阿贝尔方程将被讨论和拉格朗日动力学的逆问题进行了分析:存在两个替代拉格朗日公式证明,两个拉格朗日是一个非自然类。研究是通过达布多项式和雅可比乘子。

英文摘要:

A geometric approach is used to study the Abel first order differential equation of the first kind. The approach is based on the recently developed theory of quasi-Lie systems which allows us to characterise some particular examples of integrable Abel equations. Second order Abel equations will be discussed and the inverse problem of the Lagrangian dynamics is analysed: the existence of two alternative Lagrangian formulations is proved, both Lagrangians being of a non-natural class. The study is carried out by means of the Darboux polynomials and Jacobi multipliers.
