关于$C_n \rtimes_s C_2$上的零和正逆问题

On the direct and inverse zero-sum problems over $C_n \rtimes_s C_2$

Danilo Vilela Avelar, Fabio Enrique Brochero Martínez, Sávio Ribas

摘要:

设$C_n$是阶为$n$的循环群。本文给出了$C_n \rtimes_s C_2$上的一些零和常数的精确值,其中$s \not\equiv \pm1 \pmod n$,即$η$ -常数,Gao常数和Erdens-Ginzburg-Ziv常数(后者适用于除“小”族情形外的所有情形).作为结果,我们证明了Gao的和Zhuang-Gao的猜想。我们还解决了相关的反问题的结构特征的产品1自由序列的$C_n \rtimes_s C_2$的最大长度。

英文摘要:

Let $C_n$ be the cyclic group of order $n$. In this paper, we provide the exact values of some zero-sum constants over $C_n \rtimes_s C_2$ where $s \not\equiv \pm1 \pmod n$, namely $η$-constant, Gao constant, and Erdős-Ginzburg-Ziv constant (the latter for all but a "small" family of cases). As a consequence, we prove the Gao's and Zhuang-Gao's Conjectures for groups of this form. We also solve the associated inverse problems by characterizing the structure of product-one free sequences over $C_n \rtimes_s C_2$ of maximum length.
