Continuum-wise expansiveness for discrete dynamical systems
Revista de la Real Academia de Ciencias Exactas, Físicas y Naturales. Serie A. Matemáticas ( IF 2.9 ) Pub Date : 2021-05-09 , DOI: 10.1007/s13398-021-01056-w

In the paper, we will prove that if a continuum-wise expansive homeomorphism f of a compact connected metric space X has a local product structure then it has a periodic point. Moreover, if a nontrivial transitive set of a diffeomorphism f of a compact smooth Riemannian manifold M is \(C^1\) stably continuum-wise expansive then it is hyperbolic. These results generalize those of Mañé (Topology 17:383–396, 1978) and Lee and Park (Dyn Syst 33:228–238, 2018).

离散动力系统的连续性扩张性

在本文中,我们将证明,如果紧连通度量空间X的连续方向上的扩张同胚性f具有局部乘积结构,那么它将具有周期点。此外,如果紧致光滑黎曼流形M的一个非同构f的非平凡传递集是((C ^ 1 \))稳定连续扩展,则它是双曲线的。这些结果概括了Mañé(拓扑17:383–396,1978)和Lee and Park(Dyn Syst 33:228–238,2018)的结果。
