A space X is selectively separable if for every sequence of dense subspaces of X one can select a finite subset of each dense so that the union of these finite subsets is dense in X. In the paper mentioned in the title selective separability and variations of this property are considered in two special cases: spaces of functions and dense countable subspaces in Cantore cube. In this paper two proofs omitted in the cited article are presented.

Abstract
A space X is selectively separable if for every sequence of dense subspaces of X one can select a finite subset of each dense so that the union of these finite subsets is dense in X. In the paper mentioned in the title selective separability and variations of this property are considered in two special cases: spaces of functions and dense countable subspaces in Cantore cube. In this paper two proofs omitted in the cited article are presented.File in questo prodotto:
