关于某些等变相关流形的几何

On the geometry of some Equivariantly related manifolds

Llohann D. Sperança, Leonardo F. Cavenaghi

摘要:

我们提供了一个拓扑过程,以获得几何实现的经典和“异国情调”的$G$ -流形,如球,球上的丛和Kervaire流形。作为一个应用程序,我们申请的过程中被称为Cheeger变形产生新的度量的正里奇和几乎非负的曲率对这样的对象。

英文摘要:

We provide a topological procedure to obtain geometric realizations of both classical and `exotic' $G$-manifolds, such as spheres, bundles over spheres and Kervaire manifolds. As an application, we apply the process known as Cheeger deformations to produce new metrics of both positive Ricci and almost non-negative curvature on such objects.
