具有正迷向曲率的Besse猜想

Besse conjecture with positive isotropic curvature

Seungsu Hwang, Gabjin Yun

摘要:

临界点方程作为定义在紧致流形上单位体积的常数量曲率度量空间上的总数量曲率泛函的临界点而出现。在这个方程中,在流形上存在一个函数$f$,它满足下面的$$ (1+f){\rm Ric} = Ddf + \frac{nf +n-1}{n(n-1)}sg. $$。已经证明,如果$(g, f)$是临界点方程的解,那么$g$是爱因斯坦的,所以$(M, g)$是等距于标准球的。在本文中,我们证明了这个猜想是正确的,如果给定的黎曼度量有正的迷向曲率。

英文摘要:

The critical point equation arises as a critical point of the total scalar curvature functional defined on the space of constant scalar curvature metrics of a unit volume on a compact manifold. In this equation, there exists a function $f$ on the manifold that satisfies the following $$ (1+f){\rm Ric} = Ddf + \frac{nf +n-1}{n(n-1)}sg. $$ It has been conjectured that if $(g, f)$ is a solution of the critical point equation, then $g$ is Einstein and so $(M, g)$ is isometric to a standard sphere. In this paper, we show that this conjecture is true if the given Riemannian metric has positive isotropic curvature.
