摘要

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。

Direct summands of klt singularities

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.
