对称对与矩空间
Symmetric pairs and moment spaces
摘要:
对于一个李群G,我们寻求G的“矩空间”的正确定义。一个公理是明确的,涉及一个封闭的等变三形式。我们构造这种形式的对称空间相关联的对称对(H,G)的附加结构。此外,我们证明了一个分解定理,这些对在一个紧凑的,连通的,半单李群。
英文摘要:
For a Lie group G, we seek the right definition of a "moment space" for G. One axiom is clear, involving a closed equivariant three-form. We construct this form for symmetric spaces associated to a symmetric pair (H,G) with an additional structure. Furthermore, we prove a decomposition theorem for these pairs over a compact, connected, and semisimple Lie group.
