The Hurewicz Property and the Vietoris Hyperspace

General Topology 2023-08-22 v3

Abstract

In this note, we characterize when the Vietoris space of compact subsets of a given space has the Hurewicz property in terms of a selection principle on the given space itself using kk-covers and the notion of groupability introduced by Ko\v{c}inac and Scheepers. We comment that the same technique establishes another equivalent condition to a space being Hurewicz in each of its finite powers. We end with some characterizations involving spaces of continuous functions and answer a question posed by Ko\v{c}inac.
