关于Sobolev常数的刚性定理的另一种证明

An alternative proof of a rigidity theorem for the sharp Sobolev constant

Stefano Pigola, Giona Veronelli

摘要:

本文给出了M. Ledoux和C. Xia讨论了具有非负里奇曲率的完备流形支持一个具有(几乎)最佳Sobolev常数的Euclidean型Sobolev不等式.利用同样的技巧,我们还将Ledoux-Xia的结果推广到了具有渐近非负曲率的完备流形。

英文摘要:

We provide a somewhat geometric proof of a rigidity theorem by M. Ledoux and C. Xia concerning complete manifolds with non-negative Ricci curvature supporting an Euclidean-type Sobolev inequality with (almost) best Sobolev constant. Using the same technique we also generalize Ledoux-Xia result to complete manifolds with asymptotically non-negative curvature.
