“…It has been studied in a variety of settings, including, for example, in the context of Axiom A diffeomorphisms [6], in numerical analysis [13,14,37], as an important factor in stability theory [40,43,47] and as a property in and of itself [15,22,25,30,33,34,38,40,44]. Various variants on the pseudo-orbit tracing property have also been studied including, for example, ergodic, thick, and Ramsey shadowing [7,8,18,19,36], limit, or asymptotic, shadowing [3,26,41], s-limit shadowing [3,26,30], orbital shadowing [21,33,39,41], and inverse shadowing [14,24,29]. In the first stage of this journey, Good and Meddaugh [21] introduced new variants of shadowing which precisely characterise maps for which ω f = ICT f and ω f = ICT f .…”
