互质素幂阶元的不变生成

Invariable generation with elements of coprime prime-power order

Eloisa Detomi, Andrea Lucchini

摘要:

有限群$G$是互质不变生成的,如果存在$G$的生成元集合$\{g_1, \ldots, g_d\}$,且$|g_1|, \ldots, |g_d|$的阶是两两互质的,且对所有的$x_1, \ldots, x_d \in G$,集合$\{g_1^{x_1}, \ldots, g_d^{x_d}\}$生成$G$ .在特定情况下,当$|g_1|, \ldots, |g_d|$可以被选择为素数幂时,我们说$G$是素数幂互素不变生成的。我们将讨论这些性质,并证明第二个比第一个强,但在有限可解群的特殊情况下,它们是等价的。

英文摘要:

A finite group $G$ is coprimely-invariably generated if there exists a set of generators $\{g_1, \ldots, g_d\}$ of $G$ with the property that the orders $|g_1|, \ldots, |g_d|$ are pairwise coprime and that for all $x_1, \ldots, x_d \in G$ the set $\{g_1^{x_1}, \ldots, g_d^{x_d}\}$ generates $G$. In the particular case when $|g_1|, \ldots, |g_d|$ can be chosen to be prime-powers we say that $G$ is prime-power coprimely-invariably generated. We will discuss these properties, proving also that the second one is stronger than the first, but that in the particular case of finite soluble groups they are equivalent.
