环面变体的嵌入式去奇异化

Embedded desingularization of toric varieties

Rocio Blanco, Santiago Encinas

摘要:

我们提出了一种新的方法来实现一个环面品种的嵌入式去奇异化。设$W$是由扇$Σ$定义的正则复曲面簇,$X\subset W$是复曲面嵌入。我们构造了一个有限的组合爆破序列,使得最终的严格变换$X'\subset W'$是正则的,并且$X'$与例外因子有正规交叉。

英文摘要:

We present a new method to achieve an embedded desingularization of a toric variety. Let $W$ be a regular toric variety defined by a fan $Σ$ and $X\subset W$ be a toric embedding. We construct a finite sequence of combinatorial blowing-ups such that the final strict transforms $X'\subset W'$ are regular and $X'$ has normal crossing with the exceptional divisor.
