| Abstract: |

| I'll summarize the machinery behind a recent attempt by Justin Tatch
Moore, a logician at Cornell, to prove the amenability of Thompson's
group. While this attempt was unsuccessful, the mechanism by which Moore
relates amenability to Ramsey theory - roughly, the branch of logic that
proves theorems of the form "large multicolored structures have fairly
large monochromatic substructures" - is interesting in itself and yields
some surprising results about amenable groups. |
