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.
