A note on rank 2 diagonals

Angelo Bella, Santi Spadaro

We solve two questions regarding spaces with a ( $G_{δ}$ )-diagonal of rank 2. One is a question of Basile, Bella and Ridderbos regarding weakly Lindelöf spaces with a $G_{δ}$ -diagonal o…

Cardinal invariants of cellular-Lindelof spaces

Angelo Bella, Santi Spadaro

A space $X$ is said to be "cellular-Lindelöf" if for every cellular family $U$ there is a Lindelöf subspace $L$ of $X$ which meets every element of $U$ . Cellula…

A non-discrete space $X$ with $C_{p} (X)$ Menger at infinity

Angelo Bella, Rodrigo Hernández-Gutiérrez

In a paper by Bella, Tokgös and Zdomskyy it is asked whether there exists a Tychonoff space $X$ such that the remainder of $C_{p} (X)$ in some compactification is Menger but not $σ$ -c…
