String backgrounds from Lie groups: beyond the WZW model
29 Jun 2006, 15:20 – 16:10

I will explain the role of Lie groups in the construction of (exact) string backgrounds. I will review the appearance of Lie groups admitting a bi-invariant metric in the so-called Wess-Zumino-Witten model and will then report on some work in progress with Noureddine Mohammedi in Tours on constructing exact string backgrounds out of left-invariant metrics on Lie groups.
