Convexity of Hamiltonian manifolds
Friedrich Knop
Let K be a connected Lie group and M a Hamiltonian K-manifold. In this paper, we introduce the notion of convexity of M. It implies that the momentum image is convex, the moment ma…

A connectedness property of algebraic moment maps
Friedrich Knop
Let a connected reductive group G act on the smooth connected variety X. The cotangent bundle of X is a Hamiltonian G-variety. We show that its "total moment map" has connected fib…
