Course description and aims

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.

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 irreducible representations.

Keywords

tensor product representation, regular representation, induced representation, Frobenius reciprocity

Competencies that will be developed

Specialist skills Intercultural skills Communication skills Critical thinking skills Practical and/or problem-solving skills

Out-of-Class Study Time (Preparation and Review)

To enhance effective learning, students are encouraged to spend approximately 100 minutes preparing for class and another 100 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.
