Cartan decomposition of the moment map
P. Heinzner, G. W. Schwarz
We investigate a class of actions of real Lie groups on complex spaces. Using moment map techniques we establish the existence of a quotient and a version of Luna's slice theorem a…
Spherical Stein spaces
D. Akhiezer, P. Heinzner
Let X be an irreducible reduced complex space on which a connected compact Lie group K acts by holomorphic automorphisms. Let G be the complexification of K and g the Lie algebra o…
The extended future tube conjecture for SO(1,n)
Peter Heinzner, Patrick Schuetzdeller
Let C be the open upper light cone in with respect to the Lorentz product. The connected linear Lorentz group SO acts on C and therefore diagon…
Actions of compact groups on coherent sheaves
J. Hausen, P. Heinzner
Let K be a compact Lie group and G its complexification. For a not necessarily reduced Stein K-space X we show that there is a complex space Z endowed with a holomorphic action of…
The minimum principle from a Hamiltonian point of view
Peter Heinzner
Let G be a complex Lie group, G_R a real form of G and X a G_R-stable domain of holomorphy in a complex G-manifold. If there is a G_R-invariant strictly plurisubharmonic function o…
Projectivity of moment map quotients
Peter Heinzner, Luca Migliorini
Let G be a complex reductive group and K a maximal compact subgroup. If X is a smooth projective G-variety, with a fixed (not necessarily integral) K-invariant Kaehler form, then t…
