Abstract
In this paper,it is shown that a finite group G is abelian if and only if G satisfies the following conditions:(Ⅰ) G has a power automorphism α such that CG(α) is an elementary abelian 2-group.(Ⅱ) G has no subgroup isomorphic to 2-group <a,b|a2n=b2m=1,ab=a1+2n-1>where n≥3 and n≥m.In addition, applying the above result, the author also proves that if a finite group G has a power automorphism α such that CG(α) is an elementary abelian 2-group, then G is nilpotent.关键词
