Amenability I: Introduction & Examples
Abstract: Originally introduced by von Neumann as an obstruction to admiting certain
"paradoxical" actions, amenability has since become of of the most important
distinguishing properties of countable groups. We will discuss many interesting
equivalent characterizations of amenability and results relating amenability
to other algebraic, geometric, and dynamical properties. Examples of amenable
and non-amenable groups will be given, as well as groups the amenability
of which is as of yet undetermined.
