C. G. Karthick Babu, Ranjan Bera, Mainak Ghosh, B. Sury

AI总结:

本文定义有限群 Davenport 常数的两个变体 e(G)、f(G),计算多类非阿贝尔群的相关常数,证明三者可互不相同,并验证 Bass 猜想的部分情形。

摘要:

我们对有限群 G(不一定是阿贝尔群)的 Davenport 常数 d(G) 定义了两个变体 e(G) 与 f(G)。这些自然产生的常数有助于计算 d(G),并可能具有独立的研究价值。我们计算了若干非阿贝尔群 G 的常数 d(G)、e(G)、f(G),并证明:与这些常数完全相同的阿贝尔群不同,它们三者可能彼此不同。作为结果的副产品,我们还得到了 J. Bass 猜想的若干情形。我们也计算了几类群的第 k 个 Davenport 常数。此外,我们提出了一个关于亚循环群 f(G) 的猜想,并给出了支持该猜想的证据。

英文摘要:

We define two variants $e(G)$, $f(G)$ of the Davenport constant $d(G)$ of a finite group $G$, that is not necessarily abelian. These naturally arising constants aid in computing $d(G)$ and are of potential independent interest. We compute the constants $d(G)$, $e(G)$, $f(G)$ for some nonabelian groups G, and demonstrate that, unlike abelian groups where these constants are identical, they can each be distinct. As a byproduct of our results, we also obtain some cases of a conjecture of J. Bass. We compute the $k$-th Davenport constant for several classes of groups as well. We also make a conjecture on $f(G)$ for metacyclic groups and provide evidence towards it.
