设G是一个有限群,H是G的一个子群,回想一下,如果Hg∩H = 1或对于每一个G∈G, H被称为G的一个ti -子群。本文证明,如果一个有限非幂零群G的所有非幂零子群都是ti -子群,那么G是可解的,G的所有非幂零子群都是正规的。
Let G be a finite group and H a subgroup of G. Recall that H is said to be a TI-subgroup of G if Hg∩ H = 1 or H for each g ∈ G. In this note, we prove that if all non-nilpotent subgroups of a finite non-nilpotent group G are TI-subgroups, then G is soluble, and all non-nilpotent subgroups of G are normal.
