阿贝尔簇的群结构

Group Structure of Abelian Varieties

Patrick Meisner

摘要:

设$A$是$\mathbb{F}_q$上的阿贝尔簇.设$h_A(t)$是$A$的特征多项式。Rybakov证明了,如果$h_A(t)$是无平方的,且$G$是具有$|G| = h_A(1)$的任意有限群,则对于某些$A'$,$G = A'(\mathbb{F}_q)$与$A$同构当且仅当对于所有素数$\ell$,$G$的$\ell^{th}$ Hodge多边形在$h_A(1-t)$的$\ell^{th}$牛顿多边形之下.本文推广了这一结果,得到了所有阿贝尔簇的群结构的一个分类定理。

英文摘要:

Let $A$ be an abelian variety over $\mathbb{F}_q$. Let $h_A(t)$ be the characteristic polynomial of $A$. Rybakov showed that if $h_A(t)$ is squarefree and $G$ is any finite group with $|G| = h_A(1)$, then $G = A'(\mathbb{F}_q)$ for some $A'$ isogenous to $A$ if and only if the $\ell^{th}$ Hodge polygon of $G$ is under the $\ell^{th}$ Newton polygon of $h_A(1-t)$ for all primes $\ell$. In this paper, we will extend this result to get a classification theorem for the group structure of all abelian varieties.
