关于仿射群的正则子群的进一步讨论

More on regular subgroups of the affine group

M. A. Pellegrini, M. C. Tamburini Bellani

摘要:

本文是对域$F$的仿射群$AGL_n(F)$的正则子群研究的一个新贡献。特别是,我们关联到任何分区$λ\neq (1^{n+1})$的$n+1$阿贝尔正则子群在这样一种方式,不同的分区定义非共轭子群。此外,我们还对$n\leq 4$的某些自然类型的正则子群进行了分类。我们的分类等价于$F$上维数为$n+1$的可裂局部代数的分类.我们的方法基于线性代数的经典结果,不需要计算机。

英文摘要:

This paper is a new contribution to the study of regular subgroups of the affine group $AGL_n(F)$, for any field $F$. In particular we associate to any partition $λ\neq (1^{n+1})$ of $n+1$ abelian regular subgroups in such a way that different partitions define non-conjugate subgroups. Moreover, we classify the regular subgroups of certain natural types for $n\leq 4$. Our classification is equivalent to the classification of split local algebras of dimension $n+1$ over $F$. Our methods, based on classical results of linear algebra, are computer free.
