摘要

本文研究了在位置和速度边界条件下黎曼三次方程组的存在唯一性。我们将研究限制在边界处接近测地线的立方体。换句话说,我们在测地线边界数据的邻域中考虑边界数据。我们定义一个映射来推广黎曼指数,双指数。该图用于建立初始数据和边界数据之间的对应关系。我们还利用双指数映射强调了双共轭点与沿立方的双雅可比场之间的关系。

Riemannian cubics close to geodesics at the boundaries
In this paper we investigate the existence and uniqueness of Riemannian cubics under boundary conditions on position and velocity. We restrict the study to cubics close to geodesics at the boundaries. In other words, we consider the boundary data in a neighborhood of geodesic boundary data. We define a map that generalizes the Riemannian exponential, the biexponential. This map is used to establish the correspondence between initial and boundary data. We also emphasize the relation between biconjugate points and bi-Jacobi fields along cubics by means of the biexponential map.
