Restricted set addition in finite abelian groups

Vivekanand Goswami, Raj Kumar Mistri

Let $A$ be a nonempty subset of finite abelian group $G$ of order $n$ . For an integer $h \geq 2$ , the restricted $h$ -fold sumset $h^{\land} A$ is the set of all sums of $h$ distinct…

The maximum size of sumsets in finite cyclic groups

Vivekanand Goswami, Raj Kumar Mistri

Let $A$ be a nonempty finite subset of an additive abelian group $G$ . Given a nonnegative integer $h$ , the $h$ -fold sumset $h A$ is the set of all sums of $h$ elements of $A$ , and t…
