广义拟Einstein度量的特征和积分公式

Characterizations and integral formulae for generalized quasi-Einstein metrics

Abdênago Barros, Ernani Ribeiro

摘要:

本文的目的是给出Catino在[12]中最近定义的广义准Einstein度规的结构方程。此外,假设黎曼流形是爱因斯坦流形,我们将证明它是一个具有定义良好的势函数f的空间型。最后,我们将得到这样一类紧流形的一些积分公式,它们允许得到一些刚性结果。

英文摘要:

The aim of this paper is to present some structural equations for generalized quasi-Einstein metrics which was defined recently by Catino in [12]. In addition, supposing that the Riemannian manifold is Einstein we shall show that it is a space form with a well defined potential function f. Finally, we shall derive some integral formulae for such a class of compact manifolds which permit to obtain some rigidity results.
