Title: Some set-theoretic strategies for proving Thompson's group is 
amenable

Abstract

This informal talk outlines two strategies for proving that Thompson's 
group is amenable.  This will bring together an unlikely combination of 
topics: ultrafilter dynamics of algebraic structures, Galton-Watson 
processes, rank-to-rank elementary embeddings, and Laver tables.
