除极小奇点外的分辨率I

Resolution except for minimal singularities I

Edward Bierstone, Pierre D. Milman

摘要:

本文的思想是,去奇异化不变量与自然几何信息一起可以用来计算奇异点的局部正规形。这个思想被用在两个相关的问题中:(1)我们给出了一个簇或一个除数的奇点的奇点的分解的证明,除了简单的正规交叉(即,这避免了炸毁简单的正规交叉,并且以仅具有简单的正规交叉奇点的簇或除数结束)。(2)对于更一般的正规交叉(在局部解析或形式意义上),这样的结果不成立。我们找到最小类的奇点(在低维或低余维),我们必须结束,如果我们避免炸毁正规交叉奇点。Kollar提出了研究的几个问题。

英文摘要:

The philosophy of the article is that the desingularization invariant together with natural geometric information can be used to compute local normal forms of singularities. The idea is used in two related problems: (1) We give a proof of resolution of singularities of a variety or a divisor, except for simple normal crossings (i.e., which avoids blowing up simple normal crossings, and ends up with a variety or a divisor having only simple normal crossings singularities). (2) For more general normal crossings (in a local analytic or formal sense), such a result does not hold. We find the smallest class of singularities (in low dimension or low codimension) with which we necessarily end up if we avoid blowing up normal crossings singularities. Several of the questions studied were raised by Kollar.
