论文摘要
让$ s $为klt三倍的奇异性,在一个积极特征$ p> 5 $的代数封闭场上。我们证明其当地的典型基本团体是驯服和有限的。此外,我们表明,在$ S $的大公开赛上,每一个有限的一能力都可以实现,因为它限制了超过$ s $的有限的一能力。
Let $S$ be KLT threefold singularity over an algebraically closed field of positive characteristic $p>5$. We prove that its local étale fundamental group is tame and finite. Further, we show that every finite unipotent torsor over a big open of $S$ is realized as the restriction of a finite unipotent torsor over $S$.
