具有非负中间Ricci曲率的流形中的Sobolev不等式

Sobolev inequalities in manifolds with nonnegative intermediate Ricci curvature

Hui Ma, Jing Wu

AI总结:

本文利用Alexandrov-Bakelman-Pucci方法,将Michael-Simon型Sobolev不等式推广到具有非负中间Ricci曲率的Riemannian流形中的子流形上,并由此导出极小子流形的等周不等式。

摘要:

我们利用Alexandrov-Bakelman-Pucci方法,证明了在具有非负第k中间Ricci曲率的(n+m)维Riemannian流形中,n维子流形的Michael-Simon型Sobolev不等式。这里k=min(n-1,m-1)。这些不等式将Brendle在具有非负截面曲率的Riemannian流形上的Michael-Simon型Sobolev不等式(arXiv:2009.13717)以及Dong-Lin-Lu在具有渐近非负截面曲率的Riemannian流形上的Michael-Simon型Sobolev不等式(arXiv:2203.14624)推广到k-Ricci曲率情形。特别地,这些不等式的一个简单应用给出了Riemannian流形中极小子流形的一些等周不等式。

英文摘要:

We prove Michael-Simon type Sobolev inequalities for $n$-dimensional submanifolds in $(n+m)$-dimensional Riemannian manifolds with nonnegative $k$-th intermediate Ricci curvature by using the Alexandrov-Bakelman-Pucci method. Here $k=\min(n-1,m-1)$. These inequalities extends Brendle's Michael-Simon type Sobolev inequalities on Riemannian manifolds with nonnegative sectional curvature (arXiv:2009.13717) and Dong-Lin-Lu's Michael-Simon type Sobolev inequalities on Riemannian manifolds with asymptotically nonnegative sectional curvature (arXiv:2203.14624) to the $k$-Ricci curvature setting. In particular, a simple application of these inequalities gives rise to some isoperimetric inequalities for minimal submanifolds in Riemannian manifolds.
