Lectures on Representation Theory Dragan Milicic
Hence, all irreducible representations of an abelian finite group are characters. ... Therefore, any compact group is a projective limit of compact matrix groups.

Commutative algebra and representations of finite groups - UNL Math
Regular representation becomes kG viewed as a module over itself. Definition. A kG-module P is projective if it is a direct summand of a free.
The primary goal of these lectures is to introduce a beginner to the finite- dimensional representations of Lie groups and Lie algebras. Since this goal is.
