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

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