Location:  2866 East Hall (4:00 PM to 5:30 PM)

Title:  Ultraproducts and Deligne's Interpolation Categories

Abstract:   Deligne defined certain categories which "interpolate" the representation theory of various families of groups. I will explain a bit what these categories are and why they are interesting. Then I will tell the story of me first removing the use of an ultraproduct from his construction, but then putting it back in somewhere else.
