广义复流形的奇异约化

Singular Reduction of Generalized Complex Manifolds

Timothy E. Goldberg

摘要:

在本文中,我们开发的结果在一个模拟的方向上的Sjamaar和Lerman的奇异约化的哈密顿辛流形的范围内减少哈密顿广义复流形(在林和托尔曼的意义)。具体地说,我们证明了如果紧李群以Hamilton方式作用在广义复流形上,则全局商按轨道类型的划分会导致Lin-Tolman商划分为广义复流形。这一结果也适用于哈密尔顿广义Kähler流形的约化。

英文摘要:

In this paper, we develop results in the direction of an analogue of Sjamaar and Lerman's singular reduction of Hamiltonian symplectic manifolds in the context of reduction of Hamiltonian generalized complex manifolds (in the sense of Lin and Tolman). Specifically, we prove that if a compact Lie group acts on a generalized complex manifold in a Hamiltonian fashion, then the partition of the global quotient by orbit types induces a partition of the Lin-Tolman quotient into generalized complex manifolds. This result holds also for reduction of Hamiltonian generalized Kähler manifolds.
