On covering properties of end and ray spaces

Rodrigo Rey Carvalho, Matheus Duzi, Vinicius de Oliveira Rodrigues

We provide new results on combinatorial characterizations of covering properties in end spaces and ray spaces. In particular, we characterize the Lindelöf degree, the extent, the R…

On Products of $Δ$ -sets

Rodrigo Rey Carvalho, Vinicius de Oliveira Rodrigues

We prove the consistency of the existence of a $Q$ -set whose square is not a $Δ$ -set and that if there is a $Δ$ -set, then there exists a $Δ$ -set whose all finite powers are $Δ$ -set…
