Title: Moduli of principal bundles and the wonderful compactification

2013.11.19 | Christine Dilling

Date Wed 26 May
Time 15:45 16:45
Location Aud. D3


I will describe ongoing joint work with Johan Martens about moduli spaces of principal bundles, with reductive structure group, on a twice-punctured curve of genus zero.

I will explain how they can be used to construct the wonderful compactification of the group in the sense of De Concini-Procesi if the group has trivial center.

Furthermore, if the group has nontrivial center, we get a new compactification which is a smooth Deligne-Mumford stack.


Before this seminar there will be coffee and cake outside the seminar room
