  • Basic notions on Lie groups and Lie algebras: Relationship between Lie groups and Lie algebras, exponential function, rough classification of Lie algebras, fundamental theorems (Engel, Lie, Cartan...).
  • Structure theory of simple Lie algebras: Cartan subalgebras, roots, Weyl group, universal enveloping algebra.
  • Representation theory: Fundamentals of finite-dimensional theory, highest weights, Weyl chambers, possibly Verma modules.

Qualification Goals

The students shall

  • learn the algebraization of a fundamental concept of symmetry,
  • learn about the interaction of geometric and algebraic methods,
  • practice mathematical working methods (development of mathematical intuition and its formal justification, training of abstraction and formulating proofs),
  • improve their oral communication skills in the exercises by practicing free speech in front of an audience and during discussion.


None. The competences taught in the following modules are recommended: either Foundations of Mathematics and Linear Algebra I and Linear Algebra II or Basic Linear Algebra, either Analysis I and Analysis II or Basic Real Analysis. Basic knowledge of algebra is advantageous, but not mandatory.

This page describes a module according to the latest valid module guide in Winter semester 2020/21. Most rules valid for a module are not covered by the examination regulations and can therefore be updated on a semesterly basis. The following versions are available in the online module guide:

The module guide contains all modules, independent of the current event offer. Please compare the current course catalogue in Marvin.
