Subsequence Sums of Zero-sum free Sequences II

Pingzhi Yuan

Let $G$ be a finite abelian group, and let $S$ be a sequence over $G$ . Let $f (S)$ denote the number of elements in $G$ which can be expressed as the sum over a nonempty subsequence…

Davenport constant with weights

Pingzhi Yuan, Xiangneng Zeng

For the cyclic group $G = Z / n Z$ and any non-empty $A \in Z$ . We define the Davenport constant of $G$ with weight $A$ , denoted by $D_{A} (n)$ , to be the least na…

Coefficients of cyclotomic polynomials

Pingzhi Yuan

Let $a (n, k)$ be the $k$ -th coefficient of the $n$ -th cyclotomic polynomial. Recently, Ji, Li and Moree \cite{JLM09} proved that for any integer $m \geq 1$ , $\{a(mn, k)| n, k\in\mathb…
