Conference on Geometric Methods in Representation Theory

November 22-24, 2014

Conference Program:

We are planning a conference dinner on Saturday evening, November 22. We have asked all participants on the participant list to tell us whether they will attend or not and whether they will bring a guest. There will be a limited number of seats available, so if you are interested in coming to dinner, please let us know soon, so we can tell you if you can still join. Everyone will pay for their own food and drink.


Conference Schedule:

All talks will be in MACLEAN HALL, rooms 110 MacLean Hall and 118 MacLean Hall.
MacLean Hall is a 5-minute walk from the Iowa House Hotel and a 2-minute walk from the Capitol St. Ramp. Parking is not entirely cheap in Iowa City.

ABSTRACTS of all talks

Schedule change Monday, November 24, due to illness

All non-parallel talks take place in 118 MacLean Hall.
