# Divisors computing minimal log discrepancies on lc surfaces

@inproceedings{Liu2021DivisorsCM, title={Divisors computing minimal log discrepancies on lc surfaces}, author={Jihao Liu and Lingyao Xie}, year={2021} }

Let (X ∋ x,B) be an lc surface germ. If X ∋ x is klt, we show that there exists a divisor computing the minimal log discrepancy of (X ∋ x,B) that is a Kollár component of X ∋ x. If B 6= 0 or X ∋ x is not Du Val, we show that any divisor computing the minimal log discrepancy of (X ∋ x,B) is a potential lc place of X ∋ x.

Abstract We study a divisor computing the minimal log discrepancy on a smooth surface. Such a divisor is obtained by a weighted blow-up. There exists an example of a pair such that any divisor…

We prove that among all Kollar components obtained by plt blow ups of a klt singularity $o \in (X, D)$, there is at most one that is (log-)K-semistable. We achieve this by showing that if such a…
