Abstract
Let be a field and a finite be sufficiently small in terms of the characteristic of if . We strengthen the "threshold" sum-product inequality due to Roche-Newton, Rudnev and Shkredov, to as well as The latter inequality is "threshold-breaking", for it shows for , one has with if is sufficiently small. This implies that regardless of ,
