Abstract
Abstract First, we introduce the concepts of equicontinuity, expansivity , ergodic shadowing property, and chain transitivity in uniform space. Second, we study the dynamical properties of equicontinuity, expansivity , ergodic shadowing property, and chain transitivity in the hyperspace of uniform space. Let (X,μ) \left(X,\mu ) be a uniform space, (C(X),Cμ) \left(C\left(X),{C}^{\mu }) be a hyperspace of (X,μ) \left(X,\mu ) , and f:X→X f:X\to X be uniformly continuous. By using the relationship between original space and hyperspace, we obtain the following results: (a) the map f f is equicontinous if and only if the induced map Cf {C}^{f} is equicontinous; (b) if the induced map Cf {C}^{f} is expansive, then the map f f is expansive; (c) if the induced map Cf {C}^{f} has ergodic shadowing property, then the map f f has ergodic shadowing property; (d) if the induced map Cf {C}^{f} is chain transitive, then the map f f is chain transitive. In addition, we also study the topological conjugate invariance of (G,h) \left(G,h) -shadowing property in metric G G - space and prove that the map S S has (G,h) \left(G,h) -shadowing property if and only if the map T T has (G,h) \left(G,h) -shadowing property. These results generalize the conclusions of equicontinuity, expansivity, ergodic shadowing property, and chain transitivity in hyperspace.
