Inverse problems for sumset sizes of finite sets of integers

Abstract: Let $A$ be a finite set of integers and let $hA$ be its $h$-fold sumset. This paper investigates the sequence of sumset sizes $( |hA| ){h=1}^{\infty}$, the relations between these sequences for affinely inequivalent sets $A$ and $B$, and the comparative growth rates and configurations of the sumset size sequences $( |hA| ){h=1}^{\infty}$ and $( |hA| )_{h=1}^{\infty}$.
