Kac-Moody groups – University of Copenhagen


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.

Schedule and Lecture Notes are available here.  

Please also see our calendar for individual announcements of talks.

Venue: Centre for Symmetry and Deformation, KU. For information how to get to the Department of Mathematical Sciences click here.  Other locations of interest, such as the location the conference dinner, can be found on the Masterclass map.

Registration: If you would like to participate please fill out our registration form until May 15, 2013.

Funding: Partial support is available for graduate students and postdocs at a flat rate of up to 2500 DKK. To apply, please send an email to foley@math.ku.dk with a short research description or a link to information about your research. The deadline for application is May 10, 2013.

Accommodation: Participants are asked to book their own accommodation. We recommend Hotel 9 Små Hjem, which is pleasant and inexpensive and offers rooms with a kitchen. Other inexpensive alternatives are CabInn that has several locations in Copenhagen: the Hotel City (close to Tivoli), Hotel Scandivania (Frederiksberg, close to the lakes), and Hotel Express (Frederiksberg) are the most convenient locations; the latter two are 2.5-3 km from the math department. Somewhat more expensive - and still recommended - options are Hotel Nora and Ibsen's Hotel.

Organizer: John Foley (Copenhagen)
