Lang-Trotter猜想的一个改进版本

A refined version of the Lang-Trotter Conjecture

Stephan Baier, Nathan Jones

摘要:

设$E$为有理数上定义的椭圆曲线,$r$为固定整数。Lang和Trotter利用与$E$的除域和Sato-Tate分布的Chebotarev定理一致的概率模型,给出了直到$x$的素数个数的渐近公式,其中Frobenius迹等于$r$,其中$r$是{ \it固定}整数。然而,如本文所示,对于误差项具有一致界的区间$|r|\le 2\sqrt{x}$中的{ \it all} $r$,这种渐近估计不成立,因为这种估计与Chebotarev密度定理以及Sato-Tate猜想相矛盾。本文的目的是将Lang-Trotter猜想改进为一个渐近公式,该公式对区间$|r|\le 2\sqrt{x}$中的任意整数$r$具有一致误差项.我们证明了我们的改进与Chebotarev定理为一个固定的部门领域的一致性,并与Sato-Tate猜想。我们还提出了数值证据的改进猜想。

英文摘要:

Let $E$ be an elliptic curve defined over the rational numbers and $r$ a fixed integer. Using a probabilistic model consistent with the Chebotarev theorem for the division fields of $E$ and the Sato-Tate distribution, Lang and Trotter conjectured an asymptotic formula for the number of primes up to $x$ which have Frobenius trace equal to $r$, where $r$ is a {\it fixed} integer. However, as shown in this note, this asymptotic estimate cannot hold for {\it all} $r$ in the interval $|r|\le 2\sqrt{x}$ with a uniform bound for the error term, because an estimate of this kind would contradict the Chebotarev density theorem as well as the Sato-Tate conjecture. The purpose of this note is to refine the Lang-Trotter conjecture, by taking into account the "semicircular law", to an asymptotic formula that conjecturally holds for arbitrary integers $r$ in the interval $|r|\le 2\sqrt{x}$, with a uniform error term. We demonstrate consistency of our refinement with the Chebotarev theorem for a fixed division field, and with the Sato-Tate conjecture. We also present numerical evidence for the refined conjecture.
