Let G be a group and \(\mathrm{IA}(G)\) denote the group of all automorphisms of G, which induce identity map on the abelianized group \(G_{ab}=G/G'\). Also the group of those \(\mathrm{IA}\)-automorphisms which fix the centre element-wise is denoted by \(\mathrm{IA_Z}(G)\). In the present article, among other results and under some condition we prove that the derived subgroups of finite p-groups, for which \(\mathrm{IA_Z}\)-automorphisms are the same as central automorphisms, are either cyclic or elementary abelian.

$$ \ mathrm {IA_Z} $$ IA Z上的某些属性-组的自同构

G ^是一个群,\(\ mathrm {IA}(G)\)表示的基团的所有构的ģ,从而诱发身份地图上的abelianized组\(G_ {AB} = G / G'\) 。那些固定中心元素的\(\ mathrm {IA} \)-自同构的组也用\(\ mathrm {IA_Z}(G)\)表示。在本文章中,除其它结果和一些条件下,我们证明了有限的衍生亚群p -基团,对此\(\ mathrm {IA_Z} \) -automorphisms是相同的中央构,或者是环状的或基本阿贝尔。
