摘要 称群G的一个子群H在G中是E-可补的,如果存在G的一个子群T使得G=HT且T∩H≤HeG ,其中eGH由包含在H中的G的所有s-置换嵌入子群生成.利用G的2-极小子群的E-可补性得到了有限群成为p-幂零群的一个充分条件,推广了近来的一些结果. A subgroup H of a group G is said to be E-supplemented in G if there exists a subgroup T of G such that G=HT and eGH?T ≤H , where eGH denotes the subgroup of H generated by all those subgroups of H which are s-permutably embedded in G . By using the E-supplementation of 2-minimal subgroups of G , a sufficient condition for a finite group to be p-nilpotent is obtained and some recent results can be generalized.
