共形向量场的本质点

Essential points of conformal vector fields

Florin Belgun, Andrei Moroianu, Liviu Ornea

摘要:

对于黎曼流形上的共形向量场$ξ$,如果在$ξ$是Killing的共形类中不存在局部度量,则我们说点是本质的。证明了唯一的本质点是$ξ$的孤立零点。作为应用,我们证明了$ξ$的零集的每个连通分支是全脐的。

英文摘要:

For a conformal vector field $ξ$ on a Riemannian manifold, we say that a point is essential if there is no local metric in the conformal class for which $ξ$ is Killing. We show that the only essential points are isolated zeros of $ξ$. As an application, we show that every connected component of the zero set of $ξ$ is totally umbilical.
