Selectors for sequences of subsets of hyperspaces

Abstract

For a Hausdorff space $X$ we denote be $2^X$ the family of all closed subsets of $X$. In this paper we continue to research relationships between closure -type properties of hyperspaces over a space $X$ and covering properties of $X$. We investigate selectors for sequence of subsets of the space $2^X$ with the $Z^{+}$-topology and the upper Fell topology.
