Seminar : Affine Lie Algebras

This is the page for the seminar on QFT at the University of Queensland. We focus on Affine Lie Algebras for Semester 1, 2015. The main goal is to understand various aspects of the theory of affine Lie algebras in mathematics and physics.

when : Thursdays 3-4:30 pm
where : Priestly Building Seminar Room 67-442
