Abstract

Let XX be a compact Hausdorff space, with uniformity U\mathscr{U}, and let f ⁣:XXf \colon X \to X be a continuous function. For DUD \in \mathscr{U}, a DD-pseudo-orbit is a sequence (xi)(x_i) for which (f(xi),xi+1)D(f(x_i),x_{i+1}) \in D for all indices ii. In this paper we show that pseudo-orbits trap ω\omega-limit sets in a neighbourhood of prescribed accuracy after a uniform time period. A consequence of this is a generalisation of a result of Pilyugin et al: every system has the second weak shadowing property. By way of further applications we give a characterisation of minimal systems in terms of pseudo-orbits and show that every minimal system exhibits the strong orbital shadowing property.
