Course description and aims
This course is the continuation of "Advanced topics in Algebra A1".
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.
Student learning outcomes
The goal of this course is to understand how the regular representation of a finite group (on its group algebra) decomposes into irreducibles ones.
Keywords
tensor product representation, regular representation, induced representation, Frobenius reciprocity
