欧几里得建筑物的凸秩1子集(类型为$A_2$)

Convex rank 1 subsets of Euclidean buildings (of type $A_2$)

Andreas Balser

摘要:

对于类型为$A_{2}$的欧氏建筑物$X$,我们将$\partial_{T}X$的0维子建筑物$A$分类为闭凸子集的渐近边界。特别是,我们表明,平凡的一个三元组(点的$A$)的holonomy是(基本上)足够的。为了证明这一点,我们构造了新的凸集作为凸集的并集。

英文摘要:

For a Euclidean building $X$ of type $A_{2}$, we classify the 0-dimensional subbuildings $A$ of $\partial_{T}X$ that occur as the asymptotic boundary of closed convex subsets. In particular, we show that triviality of the holonomy of a triple (of points of $A$) is (essentially) sufficient. To prove this, we construct new convex subsets as the union of convex sets.
