对一类无限正则p-进行了研究,得到了一个正则的局部幂零P-群G如果满足|G: 1(G)|〈∞,那么G是幂零的且G是可除阿贝尔P-群被有限群的扩张.进而,还研究了一类无限的非正则p-群,但它的所有真商群或者真的无限子群是正则群.在假设这类群存在拟循环子群的情况下,在定理1.2和1.3给出了这类群的结构的刻画.
This paper proves that if a locally nilpotent p-group with |G: 1(G)|〈∞ is also regular, then G is nilpotent and G is an extension of a divisible Abelian p-group by a finite p-group. Furthermore, some infinite irregular p-groups in which all proper infinite p-subgroups or proper quotients of G are regular are studied.
