Logic Seminar

A direct solution to the Generic Point Problem

Andy Zucker, Department of Mathematical Sciences, Carnegie Mellon University,

We provide a direct proof of a recent theorem of Ben-Yaacov, Melleray and Tsankov. If $G$ is a Polish group and $X$ is a minimal metrizable $G$-flow with all orbits meager, we use $X$ to produce a new $G$-flow $S_G (X)$ which is minimal and non-metrizable.
