Kähler quotient
In mathematics, specifically in complex geometry, the Kähler quotient of a Kähler manifold  by a Lie group  acting on  by preserving the Kähler structure and with moment map  (with respect to the Kähler form) is the quotient

If  acts freely and properly, then  is a new Kähler manifold whose Kähler form is given by the symplectic quotient construction.

By the Kempf-Ness theorem, a Kähler quotient by a compact Lie group  is closely related to a geometric invariant theory quotient by the complexification of .
