海森堡群中测地曲率的度量解释

A metric interpretation of the geodesic curvature in the Heisenberg group

Mathieu Kohli

摘要:

本文研究了海森堡群中最简单的次黎曼结构--弧长为参数的光滑水平曲线的测地曲率的概念。我们的目标是给出一个度量解释的概念,测地曲率作为第一个校正项的泰勒展开的距离之间的两个封闭的点的曲线。

英文摘要:

In this paper we study the notion of geodesic curvature of smooth horizontal curves parametrized by arc lenght in the Heisenberg group, that is the simplest sub-Riemannian structure. Our goal is to give a metric interpretation of this notion of geodesic curvature as the first corrective term in the Taylor expansion of the distance between two close points of the curve.
