关于周期轨道压缩度量的逆定理

Converse theorem on a contraction metric for a periodic orbit

Peter Giesl

摘要:

收缩分析使用局部准则来证明动力系统的长期行为。压缩度量是一个黎曼度量,关于它相邻解之间的距离收缩。如果在垂直于流的所有方向上的相邻解是收缩的,则存在唯一的周期轨道,该周期轨道是指数稳定的,并且我们得到指数吸引率的界。在本文中,我们研究了相反的问题,并表明,给定一个指数稳定的周期轨道,收缩度量存在于其吸引区域,我们可以恢复指数吸引率的界。

英文摘要:

Contraction analysis uses a local criterion to prove the long-term behaviour of a dynamical system. A contraction metric is a Riemannian metric with respect to which the distance between adjacent solutions contracts. If adjacent solutions in all directions perpendicular to the flow are contracted, then there exists a unique periodic orbit, which is exponentially stable and we obtain a bound on the rate of exponential attraction. In this paper we study the converse question and show that, given an exponentially stable periodic orbit, a contraction metric exists on its basin of attraction and we can recover the bound on the rate of exponential attraction.
