摘要

我们研究了保角群Conf（M，g）本质上和传递作用于其上的紧连通伪黎曼流形（M，g）。我们特别证明，如果Conf（M，g）的非紧半单部分是Möbius群，则（M，g）是保形平坦的。

Pseudo-Conformal actions of the Möbius group

We study compact connected pseudo-Riemannian manifolds $(M, g)$ on which the conformal group $Conf (M, g)$ acts essentially and transitively. We prove, in particular, that if the non-compact semi-simple part of $Conf (M, g)$ is the Möbius group, then $(M, g)$ is conformally flat.
