Osvaldo Guzman, Damjan Kalajdzievski
We prove that every MAD family can be destroyed by a proper forcing that preserves -points. With this result, we prove that it is consistent that $ω_{1}=\mathfrak{u}<\mathfrak{a…

Maximal almost disjoint families and pseudocompactness of hyperspaces
Osvaldo Guzmán, Michael Hrušák, Vinicius de Oliveira Rodrigues +2
We show that all maximal almost disjoint families have pseudocompact Vietoris hyperspace if and only if holds. We further stu…
