摘要

我们证明,$\mathbb {R}^n$ 的每一个具有全局吸引子的拓扑稳定同构在其全局吸引子上都是拓扑稳定的。反之则不成立。另一方面,如果局部紧凑度量空间中具有全局吸引子的同态是膨胀的,并且具有阴影性质,那么它就是拓扑稳定的。这就扩展了沃尔特斯稳定性定理(沃尔特斯,《论伪轨道追踪特性及其与稳定性的关系》,伦敦:伦敦大学出版社,2006 年)。The structure of attractors in dynamical systems, 1978, pp.)

Topological stability for homeomorphisms with global attractor

We prove that every topologically stable homeomorphism with global attractor of $\mathbb {R}^n$ is topologically stable on its global attractor. The converse is not true. On the other hand, if a homeomorphism with global attractor of a locally compact metric space is expansive and has the shadowing property, then it is topologically stable. This extends the Walters stability theorem (Walters, On the pseudo-orbit tracing property and its relationship to stability. The structure of attractors in dynamical systems, 1978, pp. 231–244).
