Basic Notions: Benjy Weiss (HUJI) - What are amenable groups and why are groups non-amenable II

Title: What are amenable groups and why are groups non-amenable Abstract: I will give an introduction to amenable groups and explain the result of Kevin Whyte that a countable non-amenable group admits a "translation-like" action by a non-abelian free group. I will also discuss (without proof) a measure theoretic analogue of this result due to D. Gaboriau and R. Lyons.
