October 3-4, 2009
to be held at the Fields Institute

Organizing Committee:
Megumi Harada (McMaster University)
Joel Kamnitzer (University of Toronto)
Kevin Purbhoo (University of Waterloo)


Broadly, the subject of our workshop is “groups and geometry”. A number of rich branches of mathematics lie at the intersection of these two large areas. More specifically, our main themes of interest are: geometric representation theory, group actions on manifolds and varieties, and combinatorial aspects of geometry and representation theory.

We plan on holding a 2-day weekend workshop with 4 to 5 talks per day. We will invite speakers and participants from different Ontario universities and other regional institutions. There will be talks by faculty, post-docs, and senior graduate students, with emphasis on a high level of mathematical and communicative quality.

The workshop is also an informal celebration of Allen Knutson's 40th birthday. We hope and intendfor the workshop to reflect Allen's wide-ranging mathematical interests which span all of the above-mentioned themes of the workshop
