Title: Refined enumerative geometry
Speaker: Catherine Ray
Special Note: We switch to Lunt 105 at 6pm.
Catherine will tell us about a new area in enumerative geometry. Using the motivic universe enumerative geometry can be refined to be valued in the Grothendieck-Witt ring. With it certain counts that were not immediate to understand classically can now be made sense of.Date: Wednesday, February 19, 2020
