关于Cheltsov和Shramov之后的22次Fano三重

On Fano threefolds of degree 22 after Cheltsov and Shramov

Kento Fujita

摘要:

已知Picard秩为1且反正则度为22的非奇异Fano三重群构成一个一维群族,该群族允许乘法群的忠实作用. Cheltsov和Shramov证明,除了两个人之外,所有人都承认Kähler-Einstein度量。在本文中,我们表明,其余的Fano三倍也承认Kähler-Einstein度量。

英文摘要:

It has been known that nonsingular Fano threefolds of Picard rank one with the anti-canonical degree 22 admitting faithful actions of the multiplicative group form a one-dimensional family. Cheltsov and Shramov showed that all but two of them admit Kähler-Einstein metrics. In this paper, we show that the remaining Fano threefolds also admit Kähler-Einstein metrics.
