$S_{h}$ -sets in abelian groups

Vivekanand Goswami, Raj Kumar Mistri

For a positive integer $h$ , a subset $A = {a_{1}, \dots, a_{k}}$ of an additive abelian group $G$ is called an $S_{h}$ -set of size $k$ if all sums of $h$ distinct elements in $S$ are d…

Signed sumsets and restricted signed sumsets in groups and fields

Raj Kumar Mistri, Nitesh Prajapati

Let $A = {a_{1}, \dots, a_{k}}$ be a nonempty finite subset of an additive abelian group $G$ . For a nonnegative integer $h$ , the \emph{ $h$ -fold signed sumset} of $A$ , denoted by $h_…

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…
