Abstract:
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
