摘要

We provide a new 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, then the universal minimal flow M(G) is nonmetrizable. In particular, we show that given X as above, the universal highly proximal extension of X is nonmetrizable.
