Set Star-Menger and Set Strongly Star-Menger Spaces [PDF]

open access: yesMathematica Slovaca, 2022
AbstractMotivated by the Arhangel’skii “s-Lindelöf cardinal function” definition, Kočinac and Konca defined and studied set covering properties and set star covering properties. In this paper, we present results on the star covering properties called set star-Menger and set strongly star-Menger.

Absolutely strongly star-Menger spaces

open access: yesTopology and Its Applications, 2013
Abstract A space X is absolutely strongly star-Menger if for each sequence ( U n : n ∈ N ) of open covers of X and each dense subset D of X, there exists a sequence ( F n : n ∈ N ) of finite subsets of D such that { St ( F n , U n ) : n ∈ N } is an open cover of X.
