Special Types of Maps between HyperspacesĮxercises 76. Some of the results of the study of basic properties such as compactness, connectedness, and separation axioms are that X is regular if and only if. Moreover, if d is a T 1 quasi-metric, then the hyperspace is algebraic, and the set of all finite subsets forms a base for it. We show that K 0(X), equipped with the Hausdorff quasi-pseudometric H d forms a (sequentially) Yoneda-complete space.

We provethat f has shadowing (h-shadowing) if and only if 2f has shadowing(h-shadowing).Alejandro Illanes and Sam B. PDF On Apr 1, 1970, James Keesling published Normality and Properties Related to Compactness in Hyperspaces Find, read and cite all the research you. (2) D is relatively countably compact in X. We provethat f has shadowing (h-shadowing) if and only if 2f has shadowing(h-shadowing).ĪB - Given a nonempty compact metric space X and a continuousfunction f : X → X, we study shadowing and h-shadowing forthe induced maps on hyperspaces, particularly in symmetric products,Fn(X), and the hyperspace of compact subsets of X, 2X. respectively the hyperspaces of nonempty closed subsets, nonempty closed con- nected subsets, nonempty compact subsets, and nonempty subcontinua of X, each.
