$C$ -embedding, Lindelöfness, and Čech-completeness

Alan Dow, Klaas Pieter Hart, Jan van Mill +1

We show that in the class of Lindelöf Čech-complete spaces the property of being $C$ -embedded is quite well-behaved. It admits a useful characterization that can be used to show th…

Closed copies of $N$ in $R^{ω_{1}}$

Alan Dow, Klaas Pieter Hart, Jan van Mill +1

We investigate closed copies of~ $N$ in powers of~ $R$ with respect to $C^{*}$ - and $C$ -embedding. We show that $R^{ω_{1}}$ contains closed copies of~$\mathbb{…
