Classification of Multiplicity Free Hamiltonian Actions of Complex Tori on Stein Manifolds
A Hamiltonian action of a complex torus on a symplectic complex manifold is said to be multiplicity free if a general orbit is a lagrangian submanifold. To any multiplicity free Hamiltonian action of a complex torus T ∼= (C) on a Stein manifold X we assign a certain 5-tuple consisting of a Stein manifold Y , an étale map Y → t, a set of divisors on Y and elements of H(Y, Z), H(Y, C). We show th...
متن کاملPeriodic points for actions of tori in Stein manifolds
In one complex variable dynamics, Sullivan’s theorem ([6]) gives a complete classification of the Fatou components that can appear for a rational map f . Consequently we can have only periodic components U and U can be one of the following: 1. U attracting basin; 2. U parabolic domain; 3. U Siegel disk; 4. U Herman ring. Cases 3. and 4. are called rotation domains. In these cases, the rational ...
متن کاملAutomorphisms of Multiplicity Free Hamiltonian Manifolds
Consider a connected compact Lie group K acting on a connected Hamiltonian manifold M . A measure for the complexity of M is half the dimension of the symplectic reductions of M , and it is natural to study Hamiltonian manifolds with low complexity first, starting with the case of complexity zero, the so-called multiplicity free manifolds (see [GS] or [MiFo]). It has been a longstanding problem...
متن کاملMultiplicity-free Hamiltonian actions and existence
As for toric varieties, with any projective spherical variety is associated a convex polytope, and any facet of this polytope is defined by a prime divisor stable under a Borel subgroup [4]. In this paper we use the moment map to prove, for certain smooth projective spherical varieties, two characterizations of the facets that are defined by divisors stable under the full group action. As a cor...
