剩余类中素数间最大间隔的分布

On the distribution of maximal gaps between primes in residue classes

Alexei Kourbatov

摘要:

设$q>r\ge1$是互质的正整数。我们实证研究了素数$p=qn+r\le x$、$n\in{\mathbb N}$之间的最大间隙$G_{q,r}(x)$。大量的计算表明,几乎总是$G_{q,r}(x)<φ(q)\log^2x$。更确切地说,绝大多数最大间隙接近使用沃尔夫猜想的推广预测的趋势曲线$T$:$$G_{q,r}(x) ~\sim~ T(q,x)={φ(q)x\over{\rm li}(x)} \Big(2\log{{\rm li}(x)\overφ(q)} - \log x + b\Big),$$,其中$b = b(q,x) = O_q(1)$。适当重新缩放的最大间隙$G_{q,r}(x)$的分布接近于Gumbel极值分布。然而,是否存在$G_{q,r}(x)$的极限分布的问题是开放的。我们讨论了可能的推广克莱默的,香克斯,和Firoozbakht的apturtures素数在剩余类。

英文摘要:

Let $q>r\ge1$ be coprime positive integers. We empirically study the maximal gaps $G_{q,r}(x)$ between primes $p=qn+r\le x$, $n\in{\mathbb N}$. Extensive computations suggest that almost always $G_{q,r}(x)<φ(q)\log^2x$. More precisely, the vast majority of maximal gaps are near a trend curve $T$ predicted using a generalization of Wolf's conjecture: $$G_{q,r}(x) ~\sim~ T(q,x)={φ(q)x\over{\rm li}(x)} \Big(2\log{{\rm li}(x)\overφ(q)} - \log x + b\Big),$$ where $b = b(q,x) = O_q(1)$. The distribution of properly rescaled maximal gaps $G_{q,r}(x)$ is close to the Gumbel extreme value distribution. However, the question whether there exists a limiting distribution of $G_{q,r}(x)$ is open. We discuss possible generalizations of Cramer's, Shanks, and Firoozbakht's conjectures to primes in residue classes.
