Let G be a finite group. Roughly speaking, a subgroup A of G is called a local partial covering subgroup if AG=AB for a suitable maximal G-invariant subgroup B of AG. Our main result is as follows: Let pd be a prime power with ppd|G|p, assume that all subgroups of pd, and all cyclic subgroups of order 4 when pd=2 and a Sylow 2-subgroup of G is nonabelian, of G are local partial covering subgroups. Then G/Opp(G) is p-supersolvable; furthermore if G is not p-supersolvable, then Opp(G)/Φ is a homogeneous Fp[G]-module where Φ/Op(G)=Φ(G/Op(G)), and each irreducible constituent has dimension dividing dlogp|Φ|p.

有限群中的局部局部覆盖子群

G为有限群。粗略地说,子组ģ称为本地部分覆盖亚组是否一种G=一种一个合适的最大ģ -invariant亚一种G。我们的主要结果如下:pd 与...成为主要力量 ppd|G|p,假设的所有子组 pd,以及4阶时的所有循环子组 pd=2G的Sylow 2子群是nonabelian,G的是局部局部覆盖子群。然后G/ØppGp-超可解的; 此外,如果G不是p-超可解的,则ØppG/Φ 是同质的 Fp[G]-模块在哪里 Φ/ØpG=ΦG/ØpG,并且每个不可约成分都有维度划分 d-日志p|Φ|p
