250091 VO Representation Theory of Groups (2015W)

This is an introductory course about linear representations of finite and infinite groups. We study both classical results such as Schur's lemma and Maschke's theorem and more advanced topics such as unitary representations of amenable groups and groups with Kazhdan's property (T). We analyze briefly a relation to group C*-algebras and infinite expander graphs. Both discrete and locally compact groups are discussed.
