设G=A×P是阿贝尔群A与极大类p-群P的半直积,其中P中的元以幂自同构的方式作用于A该文证明了G的每个Coleman自同构都是内自同构.作为该结果的一个直接推论,作者得到了这样的群G有正规化子性质.
Let G = A × P be the semidirect product of an abelian group A and a p-group P of maximal class, where P acts on A by leaving every cyclic subgroup of A invariant. It is shown that every Coleman automorphism of G is an inner automorphism. As an immediate consequence, we obtain that the normalizer property holds for such group G.
