正交标架丛的黎曼度量的Wagner提升

Wagner Lift of Riemannian metric to Orthogonal Frame Bundle

Jose Ricardo Arteaga, Mikhail Malakhaltsev

摘要:

本文构造了二维定向黎曼流形$M$上的度量$g$到$M$的标准正交标架丛的全空间$P$上的度量$\hat{g}$的提升.我们称之为\textit {瓦格纳电梯}。Viktor Vladimirovich Wagner(1908 - 1981)提出了一种技术,通过李括号将定义在非完整分布上的度量扩展到其扩展。我们将Wagner构造应用到当分布是标准正交标架丛中对应于Levi-Civita联络的无穷小联络时的特定情况。我们找到了黎曼流形$(M,g)$的几何与赋提升度量的标准正交标架丛的全空间$(P,G)$的几何之间的关系。

英文摘要:

In the present work we construct a lift of a metric $g$ on a 2-dimensional oriented Riemannian manifold $M$ to a metric $\hat{g}$ on the total space $P$ of the orthonormal frame bundle of $M$. We call this lift the \textit {Wagner lift}. Viktor Vladimirovich Wagner (1908 -1981) proposed a technique to extend a metric defined on a non-holonomic distribution to its prolongation via the Lie brackets. We apply the Wagner construction to the specific case when the distribution is the infinitesimal connection in the orthonormal frame bundle which corresponds to a Levi-Civita connection. We find relations between the geometry of the Riemannian manifold $(M,g)$ and of the total space $(P,G)$ of the orthonormal frame bundle endowed with the lifted metric.
