拉格朗日子流形与矩凸性

Lagrangian submanifolds and moment convexity

Bernhard Kroetz, Michael Otto

摘要:

考虑紧致连通辛流形M上的Hamilton环面作用。对M的某类拉格朗日子流形Q,证明了Q在动量映射下的象是凸的。作为应用,我们完成了Kostant非线性凸性定理的辛证明。

英文摘要:

We consider a Hamiltonian torus action on a compact connected symplectic manifold M. For a certain class of Lagrangian submanifolds Q of M we show that the image of Q under the momentum map is convex. As an application we complete the symplectic proof of Kostant's non-linear convexity theorem.
