中文摘要:
      非p—闭群G叫拟p—闭群,如果有G的真子群H,当(?)时.K就是p—闭群。本文证明了下列定理:定理1拟p—闭群有下述二型:Ⅰ当G可解时,2≤|π(G)|≤3。Ⅱ当G不可解时,a)G/Φ(G)为复阶单群。b)(?)为复阶单群。定理2内—5—闭群有下述二大类型:Ⅰ 5αβ阶p—基本群。Ⅱ G/Φ(G)同构于PSL(2,5),S(2)(q为奇素数)
英文摘要:
      A non-p-closed group G is called quasi-p-closed if G has a proper subgroup H suchthat each of proper subgroup K of G not contained in H isp-closed. In this paper,we-obtain the following theorems:Theorem 1 Let G be a qhasi-p-closed group。 I.If G is solvable, then II. If G is non- solvable, then a)G/φ(G)a non-abelian simple group.b) G=N×1<α>,where N/φ(N) is a non- abelian simple group.Theorem 2 Inner-5-closed G has the following two types: 1.Inner p-nilPotent groups of order 5αpβ. II G/φ(G)is isomorphic with PSL(2,5),or S(5)(where q is an odd prime).
