On a variation of selective separability using ideals

Abstract

A space XX is H-separable (Bella et al., 2009) if for every sequence (Yn)(Y_n) of dense subspaces of XX there exists a sequence (Fn)(F_n) such that for each nn FnF_n is a finite subset of YnY_n and every nonempty open set of XX intersects FnF_n for all but finitely many nn. In this paper, we introduce and study an ideal variant of H-separability, called I\mathcal{I}-H-separability.
