李代数胚和李群胚的线性化问题

Linearization Problems for Lie Algebroids and Lie Groupoids

Alan Weinstein

摘要:

在这篇综述中,我们讨论了一系列的线性化问题-泊松结构,李代数胚,李群胚。最后一个问题涉及到一个关于真群胚结构的猜想。试图证明这一点的方法平均导致问题几乎作用的紧群和几乎不变子流形的紧群作用。最后讨论了紧群的哈密顿作用的动量映射的凸性定理的可能推广。

英文摘要:

In this survey, we discuss a series of linearization problems--for Poisson structures, Lie algebroids, and Lie groupoids. The last problem involves a conjecture on the structure of proper groupoids. Attempting to prove this by the method of averaging leads to problems concerning almost actions of compact groups and almost invariant submanifolds for compact group actions. The paper ends with a discussion of possible extensions of the convexity theorems for momentum maps of hamiltonian actions of compact groups.
