从芬克到希尔伯特几何

From Funk to Hilbert Geometry

Athanase Papadopoulos, Marc Troyanov

摘要:

本文综述了$\mathbb{R}^n$中凸集的Funk度量的一些基本几何性质。特别地,我们研究了它的测地线,它的拓扑,它的度量球,它的凸性,它的非凸性理论和它的等距。希尔伯特度量是芬克度量的对称化,我们展示了希尔伯特度量的一些性质,这些性质直接来自我们证明的芬克度量的性质。

英文摘要:

We survey some basic geometric properties of the Funk metric of a convex set in $\mathbb{R}^n$. In particular, we study its geodesics, its topology, its metric balls, its convexity properties, its perpendicularity theory and its isometries. The Hilbert metric is a symmetrization of the Funk metric, and we show some properties of the Hilbert metric that follow directly from the properties we prove for the Funk metric.
