On Cartesian Products which Determine Few Distinct Distances

Abstract
Every set of points P determines Ω(|P|/log|P|) distances. A close version of this was initially conjectured by Erdős in 1946 and rather recently proved by Guth and Katz. We show that when near this lower bound, a point set P of the form A×A must satisfy |A−A|≪|A|2−2/7log1/7|A| This improves recent results of Hanson and Roche-Newton.
