GIT and symplectic stability(III)

Geometric Invariant Theory (GIT) is a powerful tool to study quotients of algebraic varieties by the action of Lie groups, related to symplectic quotients by the Kempf-Ness theorem. From both points of view a notion of stability for the orbits of the group action plays a prominent role.

In the lectures we will give the basic notions and ideas behind GIT stability, symplectic stability and the Kempf-Ness theorem.

The Informal Geometry Seminar, as its name says, is an informal seminar for graduate students and postdocs at IST to share their ideas with each other and a good place to ask simple questions without any pressure.
