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
