Masterclass on

Kac-Moody groups: structure, geometry and homotopy

June 3-7, 2013

Content:  Walter Freyn and Nitu Kitchloo will give two coordinated mini-courses that will proceed from an elementary level to develop a working knowledge of the structure, geometry and homotopy theory Kac-Moody groups and selected research topics.

  • Freyn's series will focus on Kac-Moody geometry including: the geometry of symmetric spaces, Kac-Moody symmetric spaces, and twin buildings and cities.
  • Kitchloo's series will focus on the unitary form of a Kac-Moody group and its classifying spaces including: basic Kac-Moody Lie algebra theory, the homotopical and (co)homological structure of Kac-Moody groups and classifying spaces, and Kac-Moody representation and K-theory.

There will be additional talks both to support this development and on research topics by other external participants.  Lectures will be supplemented by disscussion sessions.
