New Hindman spaces

Rafał Filipów, Krzysztof Kowitz, Adam Kwela +1

We introduce a method that allows to turn topological questions about Hindman spaces into purely combinatorial questions about the Katětov order of ideals on $N$ . We also…

On the structure of Borel ideals in-between the ideals $E D$ and $Fin \otimes Fin$ in the Katětov order

Pratulananda Das, Rafał Filipów, Szymon Głąb +1

For a family $F \subseteq ω^{ω}$ we define the ideal $I (F)$ on $ω \times ω$ to be the ideal generated by the family $\{A\subseteq ω\timesω:\exists f\in \ma…
