Abstract:We study the connections between the stability properties, the Morse index, and the Conley-Zehnder index of a periodic orbit in Lagrangian systems. We obtain an extremely simple criterion for linear instability for certain periodic orbits.

Conley–Zehnder指数理论在周期轨道上的不稳定性

摘要:我们研究了拉格朗日系统中周期轨道的稳定性,莫尔斯指数和康利-曾德尔指数之间的联系。对于某些周期轨道,我们获得了一个非常简单的线性不稳定性判据。
