关于非内自同构猜想的注记

A note on non-inner automorphism conjecture

P. Komma

摘要:

本文证明了每一个$2$生成元有限$p$群$G$都有一个非内自同构的$p$级自同构,使$G^pγ_4(G)$按元素固定($p\ge 5$).证明了满足$|Ω_1(Z_2(G))|=p^2$的$2$ -生成元有限$3$ -群有一个保持$G^pγ_3(G)$按元素固定的$p$阶的非内自同构.作为结果,我们证明了上类$4$($p\ge 3$)和上类$5$($p\ge 5$)的每个有限$p$ -群的非内自同构猜想.

英文摘要:

In this paper we prove that every $2$-generator finite $p$-group $G$ has a non-inner automorphism of order $p$ leaving $G^pγ_4(G)$ elementwise fixed ($p\ge 5$). Moreover, we prove a $2$-generator finite $3$-group satisfying $|Ω_1(Z_2(G))|=p^2$ has a non-inner automorphism of order $p$ leaving $G^pγ_3(G)$ elementwise fixed. As a consequence we prove the non-inner automorphism conjecture for every finite $p$-group of coclass $4$ ($p\ge 3$), and coclass $5$ ($p\ge 5$).
