半黎曼淹没中的Maslov指数

Maslov index in semi-Riemannian submersions

Erasmo Caponio, Miguel Angel Javaloyes, Paolo Piccione

摘要:

通过确定在底空间中沿投影测地线$π\circγ:I\to B$的相应物体与相应物体的显式关系,研究了半黎曼浸没$π:M\to B$全空间中水平测地线$γ:I\to M$的焦点和Maslov指标.我们利用这个结果来计算一个(类空)测地线在一个平稳的时空,这是正交的类时基灵向量场的焦点Maslov指数。

英文摘要:

We study focal points and Maslov index of a horizontal geodesic $γ:I\to M$ in the total space of a semi-Riemannian submersion $π:M\to B$ by determining an explicit relation with the corresponding objects along the projected geodesic $π\circγ:I\to B$ in the base space. We use this result to calculate the focal Maslov index of a (spacelike) geodesic in a stationary space-time which is orthogonal to a timelike Killing vector field.
