极大类$p$ -群图中的Galois树

Galois trees in the graph of $p$-groups of maximal class

Alexander Cant, Heiko Dietrich, Bettina Eick, Tobias Moede

摘要:

对与极大类的有限$p$ -群相关的图$\mathcal{G}_p$的研究由Blackburn(1958)首先提出,并从此成为一个深入而有趣的研究课题。Leedham-Green和McKay(1976-1984)介绍了$\mathcal{G}_p$的骨架,描述了它们对$\mathcal{G}_p$结构研究的重要性,并展示了它们与代数数论的关系。在这里,我们更进一步:我们将骨架划分为所谓的伽罗瓦树,并研究它们的一般形状。在$p \geq 7$和$p \equiv 5 \bmod 6$的特殊情况下,我们证明了它们对Eick,Leedham-Green,Newman和O 'Brien(2013)提出的$\mathcal{G}_p$的周期图案有显著的影响。特别地,我们使用伽罗瓦树来证明Dietrich(2010)关于这些周期模式的猜想。

英文摘要:

The investigation of the graph $\mathcal{G}_p$ associated with the finite $p$-groups of maximal class was initiated by Blackburn (1958) and became a deep and interesting research topic since then. Leedham-Green and McKay (1976-1984) introduced skeletons of $\mathcal{G}_p$, described their importance for the structural investigation of $\mathcal{G}_p$ and exhibited their relation to algebraic number theory. Here we go one step further: we partition the skeletons into so-called Galois trees and study their general shape. In the special case $p \geq 7$ and $p \equiv 5 \bmod 6$, we show that they have a significant impact on the periodic patterns of $\mathcal{G}_p$ conjectured by Eick, Leedham-Green, Newman and O'Brien (2013). In particular, we use Galois trees to prove a conjecture by Dietrich (2010) on these periodic patterns.
