A coprimality condition on consecutive values of polynomials

Abstract

Let $f\in \mathbb{Z}[X]$ be quadratic or cubic polynomial. We prove that there exists an integer $G_f\ge 2$ such that for every integer $k\ge G_f$ one can find infinitely many integers $n\ge 0$ with the property that none of $f(n+1),f(n+2),\dots ,f(n+k)$ is coprime to all the others. This extends previous results on linear polynomials and, in particular, on consecutive integers.
