Title: Some set-theoretic strategies for proving Thompson's
group is amenable</p>
<p> Abstract <br>
</p>
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.<br>
