CM品种和大单品种
Variétés abéliennes CM et grosse monodromie finie sauvage
摘要:
本文研究数域上阿贝尔簇的有限单值群的野性部分。我们解决了Grunwald问题的形式$\mathbf{Z}/p\mathbf{Z}\wr \mathfrak{S}_n$在数域上建立CM阿贝尔簇的最大野生有限monodromy在奇素数的情况下。对于偶素情形,我们证明了CM阿贝尔簇的有限单值群的阶的2-部分上的一个新的界,并构造了达到它的簇。
英文摘要:
In this paper we study the wild part of the finite monodromy groups of abelian varieties over number fields. We solve Grunwald problems for groups of the form $\mathbf{Z}/p\mathbf{Z}\wr \mathfrak{S}_n$ over number fields to build CM abelian varieties with maximal wild finite monodromy in the odd prime case. For the even prime case we prove a new bound on the 2-part of the order of the finite monodromy group for CM abelian varieties and build varieties that reach it.
