关于格拉斯曼等价联络的几何

On the geometry of Grassmannian equivalent connections

Gianni Manno

摘要:

我们引入了流形E的n维全测地子流形方程作为E的n维子流形的二阶喷流空间的子流形。其次,我们研究了n维全测地子流形的n-Grassmannian等价联络的几何,即不含挠率且允许相同方程的n维全测地子流形的线性联络。我们定义的n-格拉斯曼结构的等价类,这样的连接,恢复n=1的情况下,理论的射影等价连接。通过引入参数化n维全测地子流形方程作为参数空间上平凡丛的二阶喷流空间的子流形,我们发现了参数化方程与非参数化方程之间的覆盖关系.在研究了这些方程的对称性之后,我们讨论了参数空间等于R^n的情形。

英文摘要:

We introduce the equation of n-dimensional totally geodesic submanifolds of a manifold E as a submanifold of the second order jet space of n-dimensional submanifolds of E. Next we study the geometry of n-Grassmannian equivalent connections, that is linear connections without torsion admitting the same equation of n-dimensional totally geodesic submanifolds. We define the n-Grassmannian structure as the equivalence class of such connections, recovering for n=1 the case of theory of projectively equivalent connections. By introducing the equation of parametrized n-dimensional totally geodesic submanifolds as a submanifold of the second order jet space of the trivial bundle on the space of parameters, we discover a relation of covering between the `parametrized' equation and the `unparametrized' one. After having studied symmetries of these equations, we discuss the case in which the space of parameters is equal to R^n.
