Abstract:

Expander graphs are highly connected sparse graphs, and play a basic role in
various areas of mathematics and computer science. Their existence follows by probabilistic considerations, but explicit constructions are much more difficult. In this seminar we describe a powerful method, first devised by Bourgain and Gamburd, to construct expanders as Cayley graphs of finite groups.
