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_…

Structure of sets with small product sets in torsion-free groups, cyclic groups of prime orders and abelian groups

Raj Kumar Mistri, Nitesh Prajapati

Let $ℓ$ and $m$ be positive integers with $ℓ \leq m$ , and let $A = (A_{1}, \dots, A_{m})$ be a finite sequence of finite subsets of a group $G$ (not necessarily abelia…
