Relative selective versions of the ccc property

Abstract

We begin a study of relative versions of selective ccc property and selective star-ccc property of topological spaces. These two properties have been introduced recently in the papers [4] and [6], respectively. A relation with game theory is also discussed.We begin a study of relative versions of selective ccc property and selective star-ccc property of topological spaces.
