Pure spinors and moment maps

I will discuss pure spinors and Dirac structures on Lie groups, and explain how they can be used in the study of group-valued moment maps, a theory introduced by Alekseev-Malkin-Meinrenken which is parallel to the usual theory of hamiltonian actions and offers a finite-dimensional approach to the study of certain moduli spaces. This is joint work with A. Alekseev and E. Meinrenken.
