交多项式与素数

Intersective polynomials and the primes

Thai Hoang Le

摘要:

相交多项式是$\Z[x]$中的多项式,每个模都有根。例如,$P_1(n)=n^2$和$P_2(n)=n^2-1$是相交多项式,但$P_3(n)=n^2+1$不是。本文的目的是利用Green-Tao \cite{gt-chen}和Lucier \cite{lucier}的结果推导出:对于任何交多项式$h$,在素数的正相对密度的任何子集内,我们可以找到不同的素数$p_1, p_2$,使得对于某个整数$n$,$p_1-p_2=h(n)$.这样的结论在Chen素数中也成立(这里的Chen素数是指一个素数$p$,使得$p+2$是至多2个素数的乘积)。

英文摘要:

Intersective polynomials are polynomials in $\Z[x]$ having roots every modulus. For example, $P_1(n)=n^2$ and $P_2(n)=n^2-1$ are intersective polynomials, but $P_3(n)=n^2+1$ is not. The purpose of this note is to deduce, using results of Green-Tao \cite{gt-chen} and Lucier \cite{lucier}, that for any intersective polynomial $h$, inside any subset of positive relative density of the primes, we can find distinct primes $p_1, p_2$ such that $p_1-p_2=h(n)$ for some integer $n$. Such a conclusion also holds in the Chen primes (where by a Chen prime we mean a prime number $p$ such that $p+2$ is the product of at most 2 primes).
