关于有限群的动词子群的秩

On the rank of a verbal subgroup of a finite group

Eloisa Detomi, Marta Morigi, Pavel Shumyatsky

摘要:

证明了如果$w$是一个多线性换位子词,$G$是一个有限群,其中由$w$ -值生成的亚幂零子群的秩至多为$r$,则动词子群$w(G)$的秩仅根据$r$和$w$有界.在$G$是可解的情况下,我们得到了一个更好的结果--如果$G$是一个有限的可解群,其中每个由$w$ -值生成的幂零子群的秩至多为$r$,则$w(G)$的秩至多为$r+1$。

英文摘要:

We show that if $w$ is a multilinear commutator word and $G$ a finite group in which every metanilpotent subgroup generated by $w$-values is of rank at most $r$, then the rank of the verbal subgroup $w(G)$ is bounded in terms of $r$ and $w$ only. In the case where $G$ is soluble we obtain a better result -- if $G$ is a finite soluble group in which every nilpotent subgroup generated by $w$-values is of rank at most $r$, then the rank of $w(G)$ is at most $r+1$.
