A game and its relation to netweight and D-spaces
Commentationes Mathematicae Universitatis Carolinae, Tome 52 (2011) no. 4, pp. 561-568
We introduce a two player topological game and study the relationship of the existence of winning strategies to base properties and covering properties of the underlying space. The existence of a winning strategy for one of the players is conjectured to be equivalent to the space have countable network weight. In addition, connections to the class of D-spaces and the class of hereditarily Lindelöf spaces are shown.
