Content, Learning Outcome and Preconditions
Content
Subjects to be covered include: Lie groups and algebras, the exponential map, the Peter-Weyl theorem, maximal tori, roots and weights, the Weyl group, the Weyl character formula and representations of the classical groups. In addition, some applications to physics may be discussed.
Learning Outcome
After successful completion of this module, students are able to understand the representation theory of compact groups. They have a thorough grasp of the relationship between a Lie group and its Lie algebra, and are able to explain the resulting consequences for representation theory. Furthermore, students can analyze Lie groups and their representations from algebraic, differential geometric and analytical viewpoints. In particular, they are able to apply methods for constructing and decomposing representations.

Learning and Teaching Methods
Lectures, Exercises, Homework
This module consists of lectures together with accompanying exercise sessions. The lectures will convey relevant concepts, mathematical results and proof methods along with concrete examples by means of board work and through discussion with the students. This is intended to motivate students to study the literature and approach problems independently. Exercise sessions will be offered which complement the theoretical material developed in the lectures. Exercise sheets and solutions will be provided, which will help students to deepen their understanding, and independently assess their progress. The exercise sessions will be guided initially, but will proceed throughout the term to more independent work by students individually as well as in small groups.

Module Exam
Description of exams and course work
The module examination is based on an oral exam (20 minutes).
The exam will assess the ability to give precise definitions, prove selected theorems involving algebraic, differential geometric and analytical arguments, and apply results and techniques to analyze, classify and construct various algebraic objects appearing in the study of Lie groups and algebras. This includes, in particular, the problem of decomposing representations into irreducibles. With suitably chosen examples, the ability to transfer results and techniques to the analysis of related problems involving representation-theoretic concepts will be tested.

Exam Repetition
The exam may be repeated at the end of the semester.
