State and use general properties of Lie algebras, including the notions of solvable and semisimple Lie algebras.
-
Recognise and define properties of classical Lie groups.
-
Recognise and work with complex representations of Lie algebras and Lie groups
-
Use Weyl’s complete reducibility theorem
-
Use highest weight theory for representations and calculate with explicit examples
Module content
Lie algebras and Lie groups are fundamental objects of study in several disciplines of contemporary Mathematics, especially in Algebra and Mathematical Physics. The study of these objects is usually the first encounter with “classification by root data”. In itself, the classification of complex simple Lie algebras was a highlight of Mathematics in the 20th century. Subsequently such classifications have become ubiquitous. It is difficult to overstate the importance of root data in Mathematics. Another major aim of this module is to gain understanding of Representation Theory. Again, this is one of the most important facets of modern research Mathematics.
