Math 735 — Spring 2002
Topics in Algebra: Quantum Groups

 

Instructor:	Milen Yakimov
Time:	TR 11:40-12:55
Room:	Malott 205

Various applications of Hopf algebras were recently found in the fields of mathematical physics, topology, combinatorics, ring theory, completely integrable systems, and others. They extended the role of Lie groups as symmetries of different mathematical structures. We plan to discuss some of these applications according to the audience interests:

• Structure of Hopf algebras
• Representations of quantized enveloping algebras of semisimple and affine Lie algebras
• Related semiclassical structures - Poisson-Lie groups
• Invariants of knots via Hopf algebras
• Canonical bases and other combinatorial structures
• Applications to mathematical physics, Knizhnik-Zamolodchikov equation
• Completely integrable systems

There are no prerequisites for the course except knowing some elementary facts on semisimple Lie algebras and groups. We will establish connections with the topics of the courses of Professors Brown and Barbasch (Spring and Fall of 2001, respectively) but will not overlap with them.
