This course is the continuation of "Advanced courses in Algebra A".
A group representation on a vector space is a group homomorphism from a group to the group of invertible linear transformations on a vector space.
The aim of this course is to explain fundamental facts in the representation theory of finite groups; in particular, we explain tensor product representations, induced representations, and the relationship between restriction and induction of group representations.
The goal of this course is to understand how the regular representation of a finite group (on its group algebra) decomposes into irreducible representations.
