Polarized orbifolds associated to quantized Hamiltonian torus actions

چکیده

Suppose given an holomorphic and Hamiltonian action of a compact torus $T$ on polarized Hodge manifold $M$. Assume that the lifts to quantizing line bundle, so there is induced unitary representation associated Hardy space. If in addition moment map nowhere zero, for each weight $\boldsymbol{\nu}$ $\boldsymbol{\nu}$-th isotypical component space polarization finite-dimensional. Assuming transverse ray through $\boldsymbol{\nu}$, we give gometric interpretation components weights $k\,\boldsymbol{\nu}$, $k\rightarrow +\infty$, terms certain orbifolds weight. These are generally not reductions $M$ usual sense, but arise rather as quotients loci unit circle bundle polarization; this construction generalizes one weighted projective spaces sphere, viewed domain Hopf map.

Hamiltonian Torus Actions on Symplectic Orbifolds and Toric Varieties

In the first part of the paper, we build a foundation for further work on Hamiltonian actions on symplectic orbifolds. Most importantly we prove the orbifold versions of the abelian connectedness and convexity theorems. In the second half, we prove that compact symplectic orbifolds with completely integrable torus actions are classified by convex simple rational polytopes with a positive intege...

Non-Hamiltonian symplectic torus actions

An action of a torus T on a compact connected symplectic manifold M is Hamiltonian if it admits a momentum map, which is a map on M taking values in the dual of the Lie algebra of T. In 1982, Atiyah and GuilleminSternberg proved that the image of the momentum map is a convex polytope, now called the momentum polytope. In 1988, Delzant showed that if the dimension of T is half of the dimension o...

Tall Complexity One Hamiltonian Torus Actions

We study torus actions on symplectic manifolds with proper moment maps in the case that each reduced space is two-dimensional. We provide a complete set of invariants for such spaces.

Centered Complexity One Hamiltonian Torus Actions

We consider symplectic manifolds with Hamiltonian torus actions which are “almost but not quite completely integrable”: the dimension of the torus is one less than half the dimension of the manifold. We provide a complete set of invariants for such spaces when they are “centered” (see below) and the moment map is proper. In particular, this classifies the moment map preimages of all sufficientl...

Continuous Families of Hamiltonian Torus Actions

We determine conditions under which two Hamiltonian torus actions on a symplectic manifold M are homotopic by a family of Hamiltonian torus actions, when M is a toric manifold and when M is a coadjoint orbit. MSC 2000: 53D05, 57S05
