On spaces with -closed-discrete dense sets
Rodrigo R. Dias, Daniel T. Soukup
The main purpose of this paper is to study \emph{-separable spaces}, originally introduced by Kurepa as spaces; we call a space -separable iff has a dense set…
Selective game versions of countable tightness with bounded finite selections
Leandro F. Aurichi, Angelo Bella, Rodrigo R. Dias
For a topological space and a point , consider the following game -- related to the property of being countably tight at . In each inning , the first pla…
Selective Games on Binary Relations
Rodrigo R. Dias, Marion Scheepers
We present a unified approach, based on dominating families in binary relations, for the study of topological properties defined in terms of selection principles and the games asso…
Topological games and Alster spaces
Leandro F. Aurichi, Rodrigo R. Dias
In this paper we study connections between topological games such as Rothberger, Menger and compact-open, and relate these games to properties involving covers by G_δ subsets. The…
Indestructibility of compact spaces
Rodrigo R. Dias, Franklin D. Tall
In this article we investigate which compact spaces remain compact under countably closed forcing. We prove that, assuming the Continuum Hypothesis, the natural generalizations to…
