Compactifications of $ω$ and the Banach space $c_{0}$

Piotr Drygier, Grzegorz Plebanek

We investigate for which compactifications $γ ω$ of the discrete space of natural numbers $ω$ , the natural copy of the Banach space $c_{0}$ is complemented in $C (γ ω)$ . We show, in par…

Nonseparable growth of the integers supporting a measure

Piotr Drygier, Grzegorz Plebanek

Assuming $b = c$ (or some weaker statement), we construct a compactification $γ ω$ of $ω$ such that its remainder $γ ω ∖ ω$ is nonseparable and carries a st…
