Right inverses of the Kirwan map
Andratx Bellmunt
(Universitat de Barcelona / Oxford)
Abstract
We will begin by reviewing the construction of the symplectic quotient and the definition of the Kirwan map. Then we will give an overview of Kirwan's original proof of the surjectivity of this map and some generalizations of this result. Finally we will talk about the techniques that are being developed to construct right inverses for the Kirwan map.
