摘要

我们证明了对于每一个正整数$n$存在一个正数$\epsilon_n$，使得$n维环商奇点在区间$(0，\epsilon_n)$上满足mld的ACC。在证明的过程中，我们将给出仿射托复形的有限自同构群的一个几何约当性质。

Small Quotient Minimal Log Discrepancies

We prove that for each positive integer $n$ there exists a positive number $\epsilon_n$ so that $n$-dimensional toric quotient singularities satisfy the ACC for mld's on the interval $(0,\epsilon_n)$. In the course of the proof, we will show a geometric Jordan property for finite automorphism groups of affine toric varieties.
