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…

Distinct Lengths Modular Zero-sum Subsequences: A Proof of Graham's Conjecture

Weidong Gao, Y. O. Hamidoune, Guoqing Wang

Let $n$ be a positive integer and let $S$ be a sequence of $n$ integers in the interval $[0, n - 1]$ . If there is an $r$ such that any nonempty subsequence with sum $\equiv 0$ $\pmod…
