The convexity package for Hamiltonian actions on conformal symplectic manifolds
Abstract
Consider a Hamiltonian action of a compact connected Lie group on a conformal symplectic manifold. We prove a convexity theorem for the moment map under the assumption that the action is of Lee type, which establishes an analog of Kirwan s convexity theorem in conformal symplectic geometry.
