Infinite dimensional Lie algebras, spring 2014
Infinite dimensional Lie algebras, spring 2014
Lecturer
Scope
10 sp.
Type
Advanced studies. The theory of infinite dimensional Lie algebras and Lie groups is a active branch in modern mathematics with links
to integrable systems, combinatorics, and K-theory. It has also important applications in quantum physics: Quantum field theory models
in low dimensions (conformal field theory) and quantum statistical models in surface physics.
The course starts with an introduction to affine Kac-Moody algebras. We discuss also the associated infinite-dimensional Lie groups.
Finally, we study some applications to conformal field theory and K-theory.
Prerequisites
Either the course on Lie algebras and representation theory, fall semester 2013 (see the lecture notes on the course homepage),
or basics about Lie algebras and Lie groups obtained in other ways, for example through the course FYMM III, fall semester 2012 (see the
lecture notes).
Lectures
Weeks 3-9 and 11-18, Monday 10-12 in room B322 and Tuesday 10-12 in room B321.
Easter holiday 17.-23.4.
Exams
Examination by seminar talks and written reports.
