论文摘要
可以将半场k上的旗帜歧管划分为“半i圆”，该圆圈是该标志歧管上k-action的轨道。在这里，我是固定的，它对应于Weyl组中的简单反射。我们证明（对于某些k）标志歧管的连接性属性：它的任何两个点都可以通过一个有限的i-circles的有限序列与各种i的序列连接在一起。
A flag manifold over a semifield K can be partitioned into "half i-circles" which are orbits of a K-action on that flag manifold. Here i is fixed and it corresponds to a simple reflection in the Weyl group. We prove (for certain K) a connectedness property of the flag manifold: any two points of it can be joined by a finite sequence of half i-circles for various i.
