AI总结:

本文研究有限阿贝尔群 $G=(C_p)^{d-1}\times C_{pq}$ 的 Davenport 常数猜想,给出使其成立的充分条件。

摘要:

对于有限阿贝尔群 $G$,Davenport常数(记为 $D(G)$)定义为最小的正整数 $k$,使得每个长度至少为 $k$ 的序列都包含非平凡零和子序列。一个长期存在的猜想是:秩为 $d \in \mathbb{N}$ 的有限阿贝尔群 $G = C_{n_1}\times\cdots\times C_{n_d}$ 的 Davenport 常数为 $1+\sum_{i=1}^d (n_i-1)$。该猜想一般不成立,但需探究明对哪些群成立。本文考虑形如 $G = (C_p)^{d-1} \times C_{pq}$ 的群(其中 $p$ 为素数,$q\in \mathbb{N}$),并给出该猜想成立的充分条件。

英文摘要:

For a finite abelian group $G,$ the Davenport Constant, denoted by $D(G)$, is defined to be the least positive integer $k$ such that every sequence of length at least $k$ has a non-trivial zero-sum subsequence. A long-standing conjecture is that the Davenport constant of a finite abelian group $G =C_{n_1}\times\cdots\times C_{n_d}$ of rank $d \in \mathbb{N}$ is $1+\displaystyle\sum_{i=1}^d (n_i-1) $. This conjecture is false in general, but it remains to know for which groups it is true. In this paper, we consider groups of the form $G = (C_p)^{d-1} \times C_{pq},$ where $p$ is a prime and $q\in \mathbb{N}$ and provide sufficient condition when the conjecture holds true.
