Title: Representations of finite groups

Abstract: The talk is not really at the normal level of this seminar; it is closer to the Graduate Algebraic Geometry Seminar. My goal is to sketch the basics of representation theory of groups, especially finite groups. While this is partially covered in algebra courses, I would like to do it from a slightly different point of view, with the focus on representations themselves rather than on their characters. The talk is aimed at people who already know definitions and general ideas, but I will not assume much beyond that.
