我们考虑如下猜想:在一个klt芽(X,x)上,对于每个有限集I,存在一个正整数N,其性质是:对于X上指数在I中的每个R-理想J,存在X上的一个除数E,它计算(X,J)在x处的最小对数偏差,并且使得它的偏差k_E上界于N。我们表明,这意味着Shokurov的ACC猜想最小的日志差异上一个固定的klt芽,并给出一些部分结果对猜想。
We consider the following conjecture: on a klt germ (X,x), for every finite set I there is a positive integer N with the property that for every R-ideal J on X with exponents in I, there is a divisor E over X that computes the minimal log discrepancy of (X,J) at x and such that its discrepancy k_E is bounded above by N. We show that this implies Shokurov's ACC conjecture for minimal log discrepancies on a fixed klt germ and give some partial results towards the conjecture.
