设矿是一个群类,称子群日为G的F-子群,如果存在G的正规子群B使得HB G,B/(B∩HG)∈F且对满足(q,|H|)=1的任意素数q,B都包含G的一个Sylow q-子群。本文利用素数幂阶F-子群,给出有限群G为超可解的若干充分条件。
Let F be a class of groups. A subgroup H of a group G is called the F-subgroup of G if there exists a normal subgroup B of G such that HB G,B/(B∩Hc) ∈F and B contains a Sylow q- subgroup of G for any prime q with (q, |H |) = 1. By using F-subgroups of prime power order,this paper provides some sufficient conditions for G to be supersolvable.
