关于 de Polignac 猜想中形如 $p + 2^k$ 的数的一些结果

Some results on a conjecture of de Polignac about numbers of the form $p + 2^k$

Yuda Chen, Xiangjun Dai, Huixi Li

AI总结:

本文针对形如 $p + 2^k$ 的数,构造等差数列反驳 Erdős 猜想,验证 Chen 关于公差下界的猜想,并将可表示数的密度上界改进至 0.490341088858244。

摘要:

我们主要获得了关于形如 $p + 2^k$ 的数的三个结果。首先,我们构造了许多等差数列,每个数列都不包含形如 $p + 2^k$ 的数,从而像 Chen 最近所做的那样,反驳了 Erdős 的一个猜想。其次,我们验证了 Chen 的一个猜想,即任何不包含形如 $p + 2^k$ 的数的等差数列,其公差至少为 11184810。第三,我们将可表示为 $p + 2^k$ 形式的数的密度的现有上界估计改进为 0.490341088858244。

英文摘要:

We have primarily obtained three results on numbers of the form $p + 2^k$. Firstly, we have constructed many arithmetic progressions, each of which does not contain numbers of the form $p + 2^k$, disproving a conjecture by Erdős as Chen did recently. Secondly, we have verified a conjecture by Chen that any arithmetic progression that do not contain numbers of the from $p + 2^k$ must have a common difference which is at least 11184810. Thirdly, we have improved the existing upper bound estimate for the density of numbers that can be expressed in the form $p + 2^k$ to $0.490341088858244$.
