Abstract
A space X is selectively separable if for every sequence ( D n : n ∈ ω ) of dense subspaces of X one can select finite F n ⊂ D n so that ⋃ { F n : n ∈ ω } is dense in X. In this paper selective separability and variations of this property are considered in two special cases: C p spaces and dense countable subspaces in 2 κ .
