Let G be a finite group. We prove that if every self-centralizing subgroup of G is nilpotent or subnormal or a TI-subgroup, then every subgroup of G is nilpotent or subnormal. Moreover, G has either a normal Sylow p-subgroup or a normal p-complement for each prime divisor p of |G|.



中文翻译:

每个自集中子群都是幂零或次正规或 TI 子群的有限群

G为有限群。我们证明,如果G 的每个自集中子群都是幂零或次正规或 TI 子群,则G 的每个子群都是幂零或次正规的。此外,对于| 的每个素数除数pG要么有一个正规的 Sylow p -子群,要么有一个正规的p -补码。|。
