摘要
对任意群G,Frattini子群Frat(G)定义为G的极大子群的交.作者给出了任意群G的另外两种广义Frattini子群P^snFrat(G)和p^scFrat(G),分别定义为指数为素数方幂P^s的极大正规子群的交和指数为素数方幂p^s的极大特征子群的交,其中p为任意素数,并且研究了这两类子群的性质,证明了它们具有与Frat(G)类似的基本性质.
For any group G, the Frattini subgroup Frat(G) is the intersection of the maximal subgroups of G. This paper investigates two other Frattini-like subgroups, p^snFrat(G) and p^scFrat(G), which are defined as the intersection of maximal normal subgroups with index any prime power p^s and the intersection of maximal characteristic subgroups with index any prime power p' respectively. The properties of p^snFrat (G) and p^scFrat (G) are studied and results analogous to those of the Frattini subgroup are established.
