A Note on Sumsets and Restricted Sumsets

Abstract

In this note we find the optimal lower bound for the size of the sumsets HAHA and H^AH\,\hat{}A over finite sets H,AH, A of nonnegative integers, where HA=hHhAHA = \bigcup_{h\in H} hA and H^A=hHh^AH\,\hat{}A = \bigcup_{h\in H} h\,\hat{}A. We also find the underlying algebraic structure of the sets AA and HH for which the size of the sumsets HAHA and H^AH\,\hat{}A is minimum.
