注:lc 是指 log canonical ,而不是之前(错误地)以为的 local canonical。

第一段照录如次。We were led to lc thresholds of Fano varieties for a quite different reason. The paper [3] reduces Theorem 1.1 to existence of a positive lower bound for lc thresholds of anti-canonical systems of certain Fano varieties which is guaranteed by our next result.
第二段照录如次。Theorem 1.4. Let d be a natural number and eps a positive real number. Then there is a positive real number t depending only on d, eps satisfying the following. Assume
(X, B) is a projective eps-lc pair of dimension d, and
A:= - (Kx + B) is nef and big.
Then lct(X,B,|A|R) ≥ t.
.
定理1.4. 令 d 是自然数,eps是正实数。那么存在正实数 t 仅依赖于d和eps,满足如下所述。假定
