高度1交换动力系统的Galois扩张

Galois Extensions of Height-One Commuting Dynamical Systems

Ghassan Sarkis, Joel Specter

摘要:

我们考虑一个动力系统,由一对交换幂级数组成,一个是不可逆的,另一个是不挠可逆的,高度为1,系数为$p$ -adic整数。假设每个点的动力系统产生一个伽罗瓦扩展的基本领域,我们表明,这些扩展实际上是阿贝尔,并使用结果和考虑从理论领域的规范,我们还表明,动力系统必须包括一个扭转系列的极大序模。从前面的一个结果,这表明,该系列实际上必须是某个高度为1的形式群的自同态。

英文摘要:

We consider a dynamical system consisting of a pair of commuting power series, one noninvertible and another nontorsion invertible, of height one with coefficients in the $p$-adic integers. Assuming that each point of the dynamical system generates a Galois extension over the base field, we show that these extensions are in fact abelian, and, using results and considerations from the theory of the field of norms, we also show that the dynamical system must include a torsion series of maximal order. From an earlier result, this shows that the series must in fact be endomorphisms of some height-one formal group.
