里奇流的对称性

Symmetries of Ricci Flows

Enrique López, Stylianos Dimas, Yuri Bozhkov

摘要:

本文研究了$n$维流形上里奇流的Lie点对称性。并介绍了一种方法,以重新利用这些对称性,以获得特定度量的李点对称性。我们应用这种方法来检索爱因斯坦方程的李点对称性-被视为一个“静态”的里奇流-,和一些特定类型的度量的兴趣,如,在弯曲产品的流形。最后,我们使用的对称性,以获得不变的解决方案的里奇流的特定家庭的度量考虑。

英文摘要:

In the present work we find the Lie point symmetries of the Ricci flow on an $n$-dimensional manifold. and we introduce a method in order to reutilize these symmetries to obtain the Lie point symmetries of particular metrics. We apply this method to retrieve the Lie point symmetries of the Einstein equations -- seen as a "static" Ricci flow -- , and of some particular types of metrics of interest, such as, on warped products of manifolds. Finally, we use the symmetries found to obtain invariant solutions of the Ricci flow for the particular families of metrics considered.
