多步费米法向坐标

Multi-step Fermi normal coordinates

Eleni-Alexandra Kontou, Ken D. Olum

摘要:

我们推广的费米正常坐标的概念,适应测地线的情况下,切空间的歧管在基点被分解成一个直接的产品的任意数量的子空间,使我们遵循几个测地线依次找到给定的坐标点。我们计算的联系和度量作为积分的黎曼张量。在一个子空间(黎曼正规坐标)或两个子空间的情况下,我们恢复Nesterov以前发现的一些结果,使用有些不同的技术。

英文摘要:

We generalize the concept of Fermi normal coordinates adapted to a geodesic to the case where the tangent space to the manifold at the base point is decomposed into a direct product of an arbitrary number of subspaces, so that we follow several geodesics in turn to find the point with given coordinates. We compute the connection and the metric as integrals of the Riemann tensor. In the case of one subspace (Riemann normal coordinates) or two subspaces, we recover some results previously found by Nesterov, using somewhat different techniques.
