A note on the Π-property of some subgroups of finite groups
摘要
Let H be a subgroup of a finite group G. We say that H satisfies the Π-property in G if for any chief factor L/K of G, ∣G/K: NG/K(HK/K∩ L/K)∣ is a π(HK/K∩L/K)-number. We obtain some criteria for the p-supersolubility or p-nilpotency of a finite group and extend some known results by concerning some subgroups that satisfy the Π-property.
