Song Yang, Xun Yu, Zigang Zhu

AI总结:

该研究引入齐次多项式可分划性与特征集概念,完成光滑三次五重簇忠实作用群的分类(证明含20个极大群),并以此为基础分类了光滑三次四重簇自同构群的所有子群。

摘要:

本文引入齐次多项式的可分划性与特征集的概念,给出忠实作用于光滑三次五重簇的群的完整分类。具体而言,我们证明所有此类群中存在20个极大群。作为应用,我们对光滑三次四重簇自同构群的所有可能子群进行了分类。

英文摘要:

In this paper, we introduce notions of partitionability and characteristic sets of homogeneous polynomials and give a complete classification of groups faithfully acting on smooth cubic fivefolds. Specifically, we prove that there exist 20 maximal ones among all such groups. As an application, we classify all possible subgroups of the automorphism groups of smooth cubic fourfolds.
