光滑流形上向量场精确集总性的刻画

Characterization of Exact Lumpability for Vector Fields on Smooth Manifolds

Leonhard Horstmeyer, Fatihcan M. Atay

摘要:

刻画了光滑流形上光滑向量场的精确集块性。我们从四个不同的角度推导了可集块性的充要条件,从而简化和推广了欧几里得空间文献中存在的各种结果.我们引入了一个部分连接的拉回丛,这是相关的Bott连接和行为像一个李衍生物。集总条件是用集总映射的微分、其关于连接的共变导数以及它们各自的核来表示的。最后给出了一些例子来说明这一理论。

英文摘要:

We characterize the exact lumpability of smooth vector fields on smooth manifolds. We derive necessary and sufficient conditions for lumpability and express them from four different perspectives, thus simplifying and generalizing various results from the literature that exist for Euclidean spaces. We introduce a partial connection on the pullback bundle that is related to the Bott connection and behaves like a Lie derivative. The lumping conditions are formulated in terms of the differential of the lumping map, its covariant derivative with respect to the connection and their respective kernels. Some examples are discussed to illustrate the theory.
