摘要 Mazur猜想:具有阿贝尔Sylow 2-子群的有限群有正规化子性质.设G是一个有限群,N是G的一个正规子群且Z(G/N)仅有平凡单位,本文建立了由Z(G/N)中单位诱导的G的自同构与N的Coleman自同构之间的联系,在此基础上证明了若G是一个具有阿贝尔Sylow 2-子群的有限群且Z(G/F*(G))仅有平凡单位,则Mazur猜想对G成立. Mazur conjectured that the normalizer property holds for finite groups with abelian Sylow 2-subgroups.Let G be a finite group and let N be a normal subgroup of G such that Z(G/N) has only trivial units.In this paper,a connection is established between the automorphisms of G induced by units in Z(G/N) and Coleman automorphisms of N.Based on this connection,we confirm that if G is a finite group with abelian Sylow 2-subgroups and Z(G/F^*(G)) has only trivial units then Mazur's conjecture holds for G.
