The course will be devoted to an introduction to the structure and representation theory of some of the most important infinite dimensional Lie algebras: Heisenberg algebras, Virasoro algebra and Kac-Moody algebras.
In the first part we will discuss representations of the Heisenberg algebra, Virasoro algebra, affine sl(n), and relations to integrable systems.
In the second part we will discuss the structure and representation theory of Kac-Moody algebras, including character formulas and Kac-Macdonald identities.
