Abstract:
In this talk, we introduce various shadowing properties such as Hausdorff average shadowing property, Hausdorff ergodic shadowing property, periodic shadowing property when the phase space is a general topological space. We prove some related results. On a compact Hausdorff space, if $f$ has the Hausdorff average shadowing property, we show that $f^k$ has the Hausdorff average shadowing property for every positive integer $k$. Further, we show that a dynamical system with the Hausdorff ergodic shadowing property is Hausdorff chain transitive if $f$ is surjective. The content of the talk is from the following references.
