Pointwise convergence of partial functions: The Gerlits-Nagy Problem

Tal Orenshtein, Boaz Tsaban

For a set $X\sbst\R$, let $B(X)\sbst\R^X$ denote the space of Borel real-valued functions on $X$ , with the topology inherited from the Tychonoff product $R^{X}$ . Assume that for eac…

Linear $σ$ -additivity and some applications

Tal Orenshtein, Boaz Tsaban

We show that countable increasing unions preserve a large family of well-studied covering properties, which are not necessarily sigma-additive. Using this, together with infinite-c…
