建立了有限群的类保持自同构和中心自同构之间的联系。借助于中心自同构的一些性质,给出了一些有限p-群的类保持自同构是内自同构的充分条件。
Connections between class-preserving automorphisms and central automorphisms of finite groups are established.Some sufficient conditions for class-preserving automorphisms of finite p-groups to be inner automorphisms are obtained by means of certain properties of central automorphisms.
