Rigidity of negatively curved geodesic orbit Finsler spaces

TL;DR

This paper establishes that geodesic orbit Finsler spaces with strictly negative flag curvature are necessarily non-compact Riemannian symmetric spaces of rank one, revealing a rigidity phenomenon in such geometric structures.

Contribution

It proves a rigidity theorem linking negatively curved geodesic orbit Finsler spaces to well-known symmetric spaces, extending classical results to the Finsler setting.

Findings

Negatively curved geodesic orbit Finsler spaces are symmetric spaces of rank one.

Such spaces must be non-compact Riemannian symmetric spaces.

The results generalize known rigidity theorems to Finsler geometry.

Abstract

We prove some rigidity results on geodesic orbit Finsler spaces with non-positive curvature. In particular, we show that a geodesic Finsler space with strictly negative flag curvature must be a non-compact Riemannian symmetric space of rank one.
