A reciprocity on finite abelian groups involving zero-sum sequences II

Mao-Sheng Li, Hanbin Zhang

Let $G$ be a finite abelian group. For any positive integers $d$ and $m$ , let $φ_{G} (d)$ be the number of elements in $G$ of order $d$ and $M (G, m)$ be the set of all zero-sum…

On $*$ -clean group rings over finite fields

Dongchun Han, Hanbin Zhang

A ring $R$ is called clean if every element of $R$ is the sum of a unit and an idempotent. Motivated by a question proposed by Lam on the cleanness of von Neumann Algebras, Vaš int…

A reciprocity on finite abelian groups involving zero-sum sequences

Dongchun Han, Hanbin Zhang

In this paper, we present a reciprocity on finite abelian groups involving zero-sum sequences. Let $G$ and $H$ be finite abelian groups with $(∣ G ∣, ∣ H ∣) = 1$ . For any positive integer…

On generalized Erdős-Ginzburg-Ziv constants of $C_{n}^{r}$

Dongchun Han, Hanbin Zhang

Let $G$ be an additive finite abelian group with exponent $exp (G) = m$ . For any positive integer $k$ , the $k$ -th generalized Erdős-Ginzburg-Ziv constant $s_{k m} (G)$ is defin…
