Abstract

Let A ⊆ [1, N] be a set of integers with |A| ≫ $\sqrt N$. We show that if A avoids about p/2 residue classes modulo p for each prime p, then A must correlate additively with the squares S = {n2 : 1 ≤ n$\sqrt N$}, in the sense that we have the additive energy estimate

$$ E(A,S)\gg N\log N. $$
This is, in a sense, optimal.
