Selective screenability and the Hurewicz property
Liljana Babinkostova
We characterize the Hurewicz covering property in metrizable spaces in terms of properties of the metrics of the space. Then we show that a weak version of selective screenability,…
Selective screenability in topological groups
Liljana Babinkostova
We examine the selective screenability property in topological groups. In the metrizable case we also give characterizations in terms of the Haver property and finitary Haver prope…
Products and selection principles
Liljana Babinkostova, Marion Scheepers
The product of a Sierpinski set and a Lusin set has Menger's property. The product of a gamma set and a Lusin set has Rothberger's property.
Selection principles and countable dimension
Liljana Babinkostova, Marion Scheepers
We characterize countable dimensionality and strong countable dimensionality by means of an infinite game.
