ERGODIC SHADOWING, ḏ-SHADOWING AND EVENTUAL SHADOWING IN TOPOLOGICAL SPACES

Abstract

We define the notions of ergodic shadowing property, ḏ-shadowing property and eventual shadowing property in terms of the topology of the phase space. Secondly we define these notions in terms of the compatible uniformity of the phase space. When the phase space is a compact Hausdorff space, we establish the equivalence of the corresponding definitions of the topological approach and the uniformity approach. In case the phase space is a compact metric space, the notions of ergodic shadowing property, ḏ-shadowing property and eventual shadowing property defined in terms of topology and uniformity are equivalent to their respective standard definitions.
