关于$B$ -群的Bouc猜想

Bouc's conjecture on $B$-groups

Xingzhong Xu, Jiping Zhang

摘要:

Bouc提出了如下猜想:有限群$G$是幂零的当且仅当它的最大商$B$ -群$β(G)$是幂零的。他证明了当$G$可解时,这个猜想成立。在本文中,我们考虑的情况下,当$G$是不可解的。设$S$是除Chevalley群$A_{n}(q)$,$D_{n}(q)$,$E_{6}(q)$,和$^2A_{n}(q)$之外的非交换单群,若$G$中只存在一个与$S$同构的因子,则$β(G)$是不可解的,当然也不是幂零的.这意味着我们在这些情况下证明了猜想。

英文摘要:

Bouc proposed the following conjecture: a finite group $G$ is nilpotent if and only if its largest quotient $B$-group $β(G)$ is nilpotent. And he has prove that this conjecture holds when $G$ is solvable. In this paper, we consider the case when $G$ is not solvable. Let $S$ be a nonabelian simple group except the Chevalley groups $A_{n}(q)$, $D_{n}(q)$, $E_{6}(q)$, and $^2A_{n}(q)$, if there exists only one factor of $G$ which is isomorphic to $S$, then $β(G)$ is not solvable, of course, is not nilpotent. That means we prove the conjecture in these cases.
