Abstract 
Sets with small doubling numbers
Sum of convex sets. Distinct consecutive differences imply large sumset. The sumproduct problem. Continuation of the previous lecture for a better understanding of the additive structure of sets with small sumsets. We say a few words about the incompatibility of additive and multiplicative structures.
