### MATH42220: Representation Theory

Type Level Credits Availability Tied 4 20 Available in 2021/22
Tied to G1K509 Mathematical Sciences

#### Prerequisites

• Prior knowledge of Algebra at undergraduate level.

• None

• None

#### Aims

• To develop and illustrate representation theory for finite groups and Lie groups.

#### Content

• Representations of finite groups.
• Character theory.
• Modules over group algebra.
• Lie groups and Lie algebras and their representations.
• Representations of SL(2,C), SU(2), SO(3).
• Reading material on a topic related to: Representations of the symmetric group, representations over finite fields.

#### Learning Outcomes

Subject-specific Knowledge:
• By the end of the module students will: be able to solve novel and/or complex problems in Representation Theory.
• have a systematic and coherent understanding of theoretical mathematics in the field of Representation Theory.
• have acquired a coherent body of knowledge of these subjects demonstrated through one or more of the following topic areas: Representations of finite groups.
• Character tables.
• Induced representations, Frobenius reciprocity.
• Representations of abelian groups.
• Lie groups and algebras, exponential map.
• Examples of representations of Lie groups and algebras.
Subject-specific Skills:
• In addition students will have highly specialised and advanced mathematical skills in the following areas: Abstract Reasoning.
• Students will have an advanced understanding in one of the following areas: Representations of the symmetric group, representations over finite fields.
Key Skills:
• Students will have developed independent learning of an advanced topic.

#### Modes of Teaching, Learning and Assessment and how these contribute to the learning outcomes of the module

• Lectures demonstrate what is required to be learned and the application of the theory to practical examples.
• Subject material assigned for independent study develops the ability to acquire knowledge and understanding without dependence on lectures.
• Assignments for self-study develop problem-solving skills and enable students to test and develop their knowledge and understanding.
• Formatively assessed assignments provide practice in the application of logic and high level of rigour as well as feedback for the students and the lecturer on students' progress.
• The end-of-year examination assesses the knowledge acquired and the ability to solve predictable and unpredictable problems.
