Abstract

We show that direct summands (or more generally, pure images) of klt type singularities are of klt type. As a consequence, we give a different proof of a recent result of Braun, Greb, Langlois and Moraga that reductive quotients of klt type singularities are of klt type.

klt 奇点的直接求和
我们证明了 klt 型奇点的直接和(或更广义的纯像)是 klt 型的。因此,我们给出了布劳恩、格雷布、朗格卢瓦和莫拉加最近一个结果的不同证明,即 klt 型奇点的还原商都是 klt 型的。
