On the number of subsequences with a given sum in a finite abelian group

Gerard Jennhwa Chang, Sheng-Hua Chen, Yongke Qu +2

Suppose $G$ is a finite abelian group and $S$ is a sequence of elements in $G$ . For any element $g$ of $G$ , let $N_{g} (S)$ denote the number of subsequences of $S$ with sum $g$ . The…

Extremal incomplete sets in finite abelian groups

Dan Guo, Yongke Qu, Guoqing Wang +1

Let $G$ be a finite abelian group. The critical number $cr (G)$ of $G$ is the least positive integer $ℓ$ such that every subset $A \subseteq G ∖ {0}$ of cardinality…
