摘要

Let G be a finite p-group and let L*(G) = {a is an element of Z(Phi(G)) | a(2)p is an element of Z(G)}. In this paper we show that if L*(G) lies in the second center Z(2)(G) of G, then G admits a noninner automorphism of order p, when p is an odd prime, and order 2 or 4, when p = 2. Moreover, the automorphism can be chosen so that it induces the identity on the Frattini subgroup Phi(G). When p 2, this reduces the verification of the well-known conjecture that states every finite nonabelian p-group G admits a noninner automorphism of order p to the case in which
