基本群的直性

Finiteness of fundamental groups

Zhiyu Tian, Chenyang Xu

摘要:

我们证明了低维log Fano对光滑轨迹的基本群的有限性将意味着klt奇点的局部基本群的有限性。作为应用,我们证明了三维klt奇点的局部基本群和具有典型奇点的三维Fano簇的光滑轨迹的基本群总是有限的.

英文摘要:

We show that the finiteness of the fundamental groups of the smooth locus of lower dimensional log Fano pairs would imply the finiteness of the local fundamental group of klt singularities. As an application, we verify that the local fundamental group of a three dimensional klt singularity and the fundamental group of the smooth locus of a three dimensional Fano variety with canonical singularities are always finite.
