AbstractRepresentation theory of groups, algebras, quivers, based on examples and solving problems.
ObjectiveThe students will learn basic notions and techniques of representation theory and to apply these techniques in concrete situations and examples.
ContentIntroduction to representation theory with many examples. Lie algebras and universal enveloping algebra. Schur lemma, representations of a matrix algebra. Jordan-Holder theorem, extensions. Category O for sl(2). Representations of finite groups. Burnside theorem, Frobenius reciprocity. Representations of symmetric groups. Representations of GL_2(F_q). Quivers. McKay correspondence.
LiteratureThe main reference is:

[E] P.Etingof, O. Goldberg, S. Hensel, T. Liu, A. Schwendner, D. Vaintrob, E. Yudovina, Introduction to representation theory, with historical interludes by S. Gerovitch, AMS 2010.
Much of the material (but not the historical interludes) can be found at

Prerequisites / NoticeLinear algebra and basic notions of algebra. Please refresh (or learn) basic notions of multilinear algebra to be able to solve the first problems on tensor products of vector spaces in [E].

Each participant gives a presentation and is assigned a set of exercises, whose solution is published on the wiki of the seminar.
