建筑物中旗帜的正向构型与正向表征的极限

Positive configurations of flags in a building and limits of positive representations

Giuseppe Martone

摘要:

Parreau紧化的Hitchin组成部分的一个闭曲面$S$的负欧拉示性数,以这样一种方式,一个边界点对应的投影长度谱的行动$π_1(S)$上的$\mathbb R$ -欧几里德建设。在本文中,我们使用的积极性属性介绍了由福克和Goncharov希钦表示明确描述的几何形状的首选集合的公寓在限制建设。

英文摘要:

Parreau compactified the Hitchin component of a closed surface $S$ of negative Euler characteristic in such a way that a boundary point corresponds to the projectivized length spectrum of an action of $π_1(S)$ on an $\mathbb R$-Euclidean building. In this paper, we use the positivity properties of Hitchin representations introduced by Fock and Goncharov to explicitly describe the geometry of a preferred collection of apartments in the limiting building.
