Title: Some combinatorics related to the Michael space problem II
Abstract: In this talk we will continue the construction of a Michael space from an ultrafilter. The main goal is to show that the existence of a selective ultrafilter (plus \(\varepsilon\ge 0\)) is enough to construct a Michael space. If the time allows it, we will show a model of ZFC without Michael ultrafilters.
