群G中所有极大子群之交称之为G的Frattini子群。给出一种新的广义的Frattini子群——p拟Fratti—ni子群的定义,并研究基本性质,例如p拟既约性质、p拟可消性质和p拟补充性质等。同时对正规子群,同态像和直积的p拟Frattini子群也进行了研究。
The Frattini subgroup Frat (G) of a group is defined as the intersection of the maximal subgroups by G. The object of this paper is to introduee a new canonical subgroup, thepnear Frattini subgroups. Its definition is given and its properties are investigated, such as thepnear irreducibility, thepnear eliminability and thepnear supplementa- tion property. At the same time, thepnear Frattini subgroups of normal subgroups, homomorphism images and direct products of groups are also considered.
