On the Alster, Menger and D-type covering properties

open access: yesQuaestiones Mathematicae, 2021
In this paper we give new characterizations for almost Menger and weakly Menger spaces by neighborhood assignments and dene a natural weakening of almost D-spaces and weakly D-spaces. We discuss the relationships among the properties "D-type", "Menger", "

Weaker forms of the Menger property

open access: yesQuaestiones Mathematicae, 2012
In this paper we study a weaker form of the classical concept of Menger property.  This property, called weakly Menger, is independent from the Menger property and the almost Menger property.
