指数为3的K3曲面和log del Pezzo曲面

K3 surfaces and log del Pezzo surfaces of index three

Hisanori Ohashi, Shingo Taki

摘要:

我们使用K3曲面的非辛自同构的分类来获得指数为3的log del Pezzo曲面的部分分类。我们可以对具有“多重光滑因子性质”的情形进行分类,并给出其定义。我们的方法包括指数为3的商奇点的右分解的定义和一些自同构稳定的椭圆纤维化的K3曲面上的分析。特别是,我们发现几个日志德尔Pezzo表面的皮卡德数1与非复曲面奇异的指数3。

英文摘要:

We use classification of non-symplectic automorphisms of K3 surfaces to obtain a partial classification of log del Pezzo surfaces of index three. We can classify those with "Multiple Smooth Divisor Property", whose definition we will give. Our methods include the definition of right resolutions of quotient singularities of index three and some analysis of automorphism-stable elliptic fibrations on K3 surfaces. In particular we find several log del Pezzo surfaces of Picard number one with non-toric singularities of index three.
