本文给出了两种估计动力系统不变紧集的Hausdorff维数的方法:特征指数法(Kaplan-Yorke型估计)和Lyapunov函数法。在第一种方法中,使用李亚普诺夫的第一种方法,我们利用特征指数来获得这样的估计。由此建立了一致渐近稳定的密切关系。不变紧集的Hausdorff维的第二个界是通过利用Lyapunov的直接方法得到的,因此依赖于Lyapunov函数的使用。
In this paper we present two approaches to estimate the Hausdorff dimension of an invariant compact set of a dynamical system: the method of characteristic exponents (estimates of Kaplan-Yorke type) and the method of Lyapunov functions. In the first approach, using Lyapunov's first method we exploit characteristic exponents to obtain such an estimate. A close relationship with uniform asymptotic stability is hereby established. A second bound for the Hausdorff dimension of an invariant compact set is obtained by exploiting Lyapunov's direct method and thus relies on the use of Lyapunov functions.
