对π-可分群的π-可分解因子的次正规对做进一步地探讨,证明了自同构群在极大π-可分解因子的次正规对集合上有作用。作为该作用的一个直接结果,得到π-可分群的极大π-可分解因子的次正规对是共轭的。特别地,给出了极大π-可分解因子的次正规对的Frattini论断。
Based on existing results in the literature, theπ-factorable subnormal pairs ofπ-separable groups are further discussed.It is proved that the automorphism group has an action on the set of maximal π-factorable subnormal pairs. As a direct result of the action, maximalπ-factorable subnormal pairs are conjugate.In particular, Frattini argument of maximalπ-factorable subnormal pairs is obtained.
