Let G be a finite group with a normal subgroup N such that CG(N) ⩽ N. It is shown that under some conditions, Coleman automorphisms of G are inner. Interest in such automorphisms arose from the study of the normalizer problem for integral group rings.

具有自集中正态子群的有限群的 Coleman 自同构

设 G 是一个有正规子群 N 的有限群，使得 CG(N) ⩽ N。证明在某些条件下，G 的 Coleman 自同构是内在的。对这种自同构的兴趣源于对整群环的归一化问题的研究。
