Abstract
A well-known conjecture in analytic number theory states that for every pair of sets , each of size at least (for some constant ) we have that the number of pairs such that is a quadratic residue modulo differs from by . We address the probabilistic analogue of this question, that is for every fixed , given a finite group and a random subset of density , we prove that with high probability for all subsets , the number of pairs such that differs from by .
