摘要
设X是群G的非空子集,群G的子群A称为在G中X-s半置换的,如果A在G中存在一个补充T,使得对于T的任意Sylow子群Tp,都存在x∈X满足ATpx=TxpA.利用这个概念给出有限群为超可解的两个新的充分条件.
Let X be a non-empty subset of a group G. Then a subgroup A of G is said to be X-s-semipermutable in G if A has a supplement T in G such that for every Sylow subgroup Tp of T, there exists an element .r∈ X to satisfy ATOp = T^xpA. In this paper,two new sufficient conditions for supersolubility of finite groups are given by using this concept.
