G2的某些子群的分类

Classification of Certain Subgroups of G2

Andrew Fiori

摘要:

我们给出了G2型群中极大环面的有理共轭类的一个具体刻画,重点讨论了数域和p-adic域的情形。在同样的上下文中,我们刻画了G2的A2子群的有理共轭类。在得到了具体的特征之后,我们将其与可以用伽罗瓦上同调给出的更抽象的特征联系起来。我们注意到,这些结果对A2子群同时和独立开发的工作Hooda而结果对环面同时和独立开发的工作贝利-Gille-李。

英文摘要:

We give a concrete characterization of the rational conjugacy classes of maximal tori in groups of type G2, focusing on the case of number fields and p-adic fields. In the same context we characterize the rational conjugacy classes of A2 subgroups of G2. Having obtained the concrete characterization, we then relate it to the more abstract characterization which can be given in terms of Galois cohomology. We note that these results on A2 subgroups were simultaneously and independently developed in the work of Hooda whereas the results on tori were simultaneously and independently developed in the work of Beli-Gille-Lee.
