给出了两个实旗流形在复旗流形中的交集为离散的充分必要条件,其中包含一个先前已知的结果。实旗流形的离散交集是Weyl群的一个轨道,该轨道是复旗流形的一个对径集。由两个实旗流形和作为环境的复旗流形组成的三元组可由紧对称三元组构造。证明了紧对称三元组可以取为典范形式。

英文摘要

The necessary and sufficient conditions for the intersection of two real flag manifolds in a complex flag manifold to be discrete are stated including a previous known result. The discrete intersection of real flag manifolds is the orbit of a Weyl group, which is an antipodal set of a complex flag manifold. The triple of two real flag manifolds and a complex flag manifold as an ambient space is constructed from a compact symmetric triad. It is shown that the compact symmetric triad can be taken to be canonical.
