Sequences with Translates Containing Many Primes
Published online by Cambridge University Press: 20 November 2018
Abstract
Garrison [3], Forman [2], and Abel and Siebert [1] showed that for all positive integers $k$ and
$N$, there exists a positive integer
$\lambda $ such that
${{n}^{k}}\,+\,\lambda $ is prime for at least
$N$ positive integers
$n$. In other words, there exists
$\lambda $ such that
${{n}^{k}}\,+\,\lambda $, represents at least
$N$ primes.
We give a quantitative version of this result.We show that there exists $\lambda \le {{x}^{k}}$ such that
${{n}^{k}}\,+\,\lambda $, 1 ≤ n ≤ x, represents at least
$\left( \frac{1}{k}\,+\,o\left( 1 \right) \right)\,\pi \left( x \right)$ primes, as
$x\to \infty $. We also give some related results.
