例外的del Pezzo超曲面

Exceptional del Pezzo hypersurfaces

Ivan Cheltsov, Jihun Park, Constantin Shramov

摘要:

本文在$\mathbb{P}(a_{1},a_{2},a_{3},a_{4})$中计算了一类拟光滑良型del Pezzo加权超曲面的全局对数正则阈值。作为推论,我们得到了其中许多超曲面上的轨道Kähler-Einstein度量的存在性,并对$\mathbb{P}(a_{1},a_{2},a_{3},a_{4})$中的例外和弱例外拟光滑良形del Pezzo加权超曲面进行了分类.

英文摘要:

We compute global log canonical thresholds of a large class of quasismooth well-formed del Pezzo weighted hypersurfaces in $\mathbb{P}(a_{1},a_{2},a_{3},a_{4})$. As a corollary we obtain the existence of orbifold Kähler--Einstein metrics on many of them, and classify exceptional and weakly exceptional quasismooth well-formed del Pezzo weighted hypersurfaces in $\mathbb{P}(a_{1},a_{2},a_{3},a_{4})$.
