When is the beginning the end? On full trajectories, limit sets and internal chain transitivity (2004.02878v1)

Abstract: Let $f \colon X \to X$ be a continuous map on a compact metric space $X$ and let $\alpha_f$, $\omega_f$ and $ICT_f$ denote the set of $\alpha$-limit sets, $\omega$-limit sets and nonempty closed internally chain transitive sets respectively. In this paper we characterise, by introducing novel variants of shadowing, maps for which every element of $ICT_f$ is equal to (resp. may be approximated by) the $\alpha$-limit set and the $\omega$-limit set of the same full trajectory. We construct examples highlighting the difference between these properties.
