形如$[p^{1/γ}]$的殆素数

Almost primes of the form $[p^{1/γ}]$

Fei Xue, Jinjiang Li, Min Zhang

AI总结:

本文研究素数幂次取整后的殆素数问题,证明当$0.989<γ<1$时有无穷多个素数$p$使$[p^{1/γ}]$至多含7个素因子,将已有结果的8个因子改进为7个。

摘要:

令$\mathcal{P}_r$表示按重数计至多有$r$个素因子的殆素数。本文证明,当$0.989<γ<1$时,存在无穷多个素数$p$使得$[p^{1/γ}]=\mathcal{P}_7$;这改进了Banks-Guo-Shparlinski[4]此前的结果,他们证明在$γ$接近1时存在无穷多个素数$p$满足$[p^{1/γ}]=\mathcal{P}_8$。

英文摘要:

Let $\mathcal{P}_r$ denote an almost-prime with at most $r$ prime factors, counted according to multiplicity. In this paper, it is proved that, for $0.989<γ<1$, there exist infinitely many primes $p$ such that $[p^{1/γ}]=\mathcal{P}_7$, which constitutes an improvement upon the previous result of Banks-Guo-Shparlinski [4] who showed that there exist infinitely many primes $p$ such that $[p^{1/γ}]=\mathcal{P}_8$ for $γ$ near to one.
