一般阿贝尔簇的平方筛和Lang-Trotter问题

The Square Sieve and a Lang-Trotter Question for Generic Abelian Varieties

Samuel Bloom

摘要:

设$A$是$\mathbb{Q}$上的一个$g$维阿贝尔簇,它的阿德拉伽罗瓦表示在$\text{GSp}_{2g} \widehat{\mathbb{Z}}$中有开象.研究了$p$的模素数$A$的约化的自同态代数$\text{End}(A_p) \otimes \mathbb{Q} = \mathbb{Q}( π_p )$,在该约化是普通的和简单的.我们获得条件和无条件的渐近上界的素数在这个“Frobenius场”是一个指定的数域,当$A$是二维的,在Frobenius场包含一个指定的实二次数域。这些调查继续调查的变种的Lang-Trotter猜想的椭圆曲线。

英文摘要:

Let $A$ be a $g$-dimensional abelian variety over $\mathbb{Q}$ whose adelic Galois representation has open image in $\text{GSp}_{2g} \widehat{\mathbb{Z}}$. We investigate the endomorphism algebras $\text{End}(A_p) \otimes \mathbb{Q} = \mathbb{Q}( π_p )$ of the reduction of $A$ modulo primes $p$ at which this reduction is ordinary and simple. We obtain conditional and unconditional asymptotic upper bounds on the number of primes at which this "Frobenius field" is a specified number field and, when $A$ is two-dimensional, at which the Frobenius field contains a specified real quadratic number field. These investigations continue the investigations of variants of the Lang-Trotter Conjectures on elliptic curves.
