For every fixed intersective integer polynomial $h$ of degree $k \geq 2$ with positive leading coefficient, proves that a subset of ${1, \dots, N}$ avoiding nonzero values $h (1), h (2), \dots$ as differences has size $O_{h} (N^{1 - c_{k}})$ , with $c_{k} > 0$ depending only on degree. Here intersective means having a root modulo every modulus. For prime arguments, a power saving also holds when $h$ has a unit root modulo every modulus, with exponent allowed to depend on $h$ .

An integer polynomial is intersective if it has a root modulo every positive integer. For each degree k ≥ 2, we prove that there is an exponent $c_{k} > 0$ such that every set $A \subseteq {1, \dots, N}$ whose differences avoid all nonzero values $h (1), h (2), \dots$ , where h is an intersective polynomial of degree k with positive leading coefficient, satisfies $∣ A ∣ = O_{h} (N^{1 - c_{k}})$ . The implied constant may depend on h, but the power-saving exponent depends only on its degree.
