仿射联络的一个积分公式

An integral formula for affine connections

Junfang Li, Chao Xia

摘要:

在这篇文章中,我们引入了一个$2$ -参数族的仿射联络,并推导出了里奇曲率。我们首先建立一个积分Bochner技术。一方面,这种方法为我们最近在次静态流形的\cite{LX}中的工作提供了一个新的证明。另一方面,在更一般的里奇曲率条件下,这种方法得到了各种几何不等式和特征值估计.新的里奇曲率条件介于静态Ricci张量和$1$ -Bakry-Emery Ricci之间,并包括共形Ricci作为中间情形.

英文摘要:

In this article, we introduce a $2$-parameter family of affine connections and derive the Ricci curvature. We first establish an integral Bochner technique. On one hand, this technique yields a new proof to our recent work in \cite{LX} for substatic manifolds. On the other hand, this technique leads to various geometric inequalities and eigenvalue estimates under a much more general Ricci curvature conditions. The new Ricci curvature condition interpolates between static Ricci tensor and $1$-Bakry-Emery Ricci, and also includes the conformal Ricci as an intermediate case.
