Title: The Furstenberg-Zimmer structure theorem and a proof of Szemer├ędi's theorem

Abstract: The Furstenberg-Zimmer structure theorem is a way to partially recover the dichotomy between weak mixing and compact vectors inherent in the study of unitary representations of groups into the p.m.p. action setting. During this talk, I will prove one version of the Furstenberg-Zimmer theorem using some measure theoretic techniques, and then show how Szemer├ędi's theorem follows from this result.
