摘要翻译:
我们提出了一种新的方法来实现一个toric变量的嵌入式去模糊化。设$w$是由fan$\sigma$定义的正规toric变体,$x\子集w$是toric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$X'\子集W'$是正则的,并且$X'$与例外因子有正交。

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 $\Sigma$ 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.
