秩为2或低阶的幂幂零群群

Powerfully nilpotent groups of rank 2 or small order

Gunnar Traustason, James Williams

摘要:

本文继续研究强幂零群幂群。这些都是强大的$p$ -拥有一个特殊类型的中心列的群。对于每一个这样的群,人们可以附加一个强大的幂零类,这自然会导致一个强大的coclass和祖先树分类的概念。本文给出了秩为$2$的幂幂零群的一个完全分类.然后,分类将被用来达到一个精确的公式的数量的幂幂零群的秩$2$和秩序$p^{n}$。我们还将详细分析这些群体的祖先树。第二部分的文件,然后致力于一个完整的分类幂幂零群的顺序高达$p^{6}$。

英文摘要:

In this paper we continue the study of powerfully nilpotent groups. These are powerful $p$-groups possessing a central series of a special kind. To each such group one can attach a powerful nilpotency class that leads naturally to the notion of a powerful coclass and classification in terms of an ancestry tree. In this paper we will give a full classification of powerfully nilpotent groups of rank $2$. The classification will then be used to arrive at a precise formula for the number of powerfully nilpotent groups of rank $2$ and order $p^{n}$. We will also give a detailed analysis of the ancestry tree for these groups. The second part of the paper is then devoted to a full classification of powerfully nilpotent groups of order up to $p^{6}$.
