Abstract:
The Kempf-Ness theorem relates algebraic (GIT) quotients with certain symplectic quotients. We will review the construction of such quotients and prove the simplest version of the K-N theorem, in the affine case. The attempt to generalize this result to an infinite-dimensional setting led to the notion of K-stability.
