单块群的斜积群

Skew product groups for monolithic groups

Martin Bachratý, Marston Conder, Gabriel Verret

摘要:

斜态射,推广群的自同构,提供了一个基本的工具,研究定期凯莱映射,更一般地说,有限群与互补因子分解$G=BY$,其中$Y$是循环和核心自由的$G$。在本文中,我们分类所有的例子,其中$B$是单片(这意味着它有一个唯一的最小正规子群,该子群不是阿贝尔)和核心免费的$G$。作为结果,我们得到了有限非交换单群的所有真斜态射的分类。

英文摘要:

Skew morphisms, which generalise automorphisms for groups, provide a fundamental tool for the study of regular Cayley maps and, more generally, for finite groups with a complementary factorisation $G=BY$, where $Y$ is cyclic and core-free in $G$. In this paper, we classify all examples in which $B$ is monolithic (meaning that it has a unique minimal normal subgroup, and that subgroup is not abelian) and core-free in $G$. As a consequence, we obtain a classification of all proper skew morphisms of finite non-abelian simple groups.
