关于坍缩Orbifold上奇点的一个限制
A restriction for singularities on collapsing orbifolds
摘要:
一个orbifold $X$与$G_x\backslash B_r(0)$局部同胚,其中$G_x$是作用在$B_r(0)\subset{\mathbb R}^n$上的有限群,使得$G_x(0)=0$。对于具有孤立奇点的坍缩轨道褶皱,我们证明了在$|G_x|$中存在一个一致的边界。
英文摘要:
An orbifold $X$ is locally homeomorphic to $G_x\backslash B_r(0)$, where $G_x$ is a finite group acting on $B_r(0)\subset{\mathbb R}^n$, so that $G_x(0)=0$. For collapsing orbifolds with isolated singularities, we show there is a uniform bound in $|G_x|$.
