  • Every filter is homeomorphic to its square
    Medini, Andrea ; Zdomskyy, Lyubomyr
    We show that every filter ▫$\mathcal{F}$▫ on ▫$\omega$▫, viewed as a subspace of ▫$2^\omega$▫, is homeomorphic to ▫$\mathcal{F}^2$▫. This generalizes a theorem of van Engelen, who proved that this ... holds for Borel filters.
