Teaching Algebra II – groups (FR)This course deals with group theory, with particular emphasis on group actions and notions of category theory.Representation theory II – Lie algebras (EN)This is a standard course on Lie groups, Lie algebras and their representations.Representation theory III – infinite dim. algebras (EN)This course serves as an introduction to the theory of infinite-dimensional Lie algebras. Representation theory III – quantum groups (EN) This course serves as an introduction to the theory of quantum groups, with particular emphasis on using their R-matrices to obtain link invariants.
