Sept 17 Karsten Gimre Discrete groups and limits of metric spaces Discrete groups are of fundamental importance in many fields, including differential geometry, topology and number theory. We will survey some of the mathematics behind a important theorem due to Mikhael Gromov which studies the subclass of discrete groups given by those of polynomial growth. A key novel idea introduced by Gromov's proof is to view groups as geometric objects, reducing the study of groups of polynomial growth to a problem about metric spaces.
