摘要: 证明了下列结果: 设R是一个2-非挠质环; J 是一个Jordan理想, 且是R的子环. 如果φ: R→R是一个自同构, 且对所有的u∈J, 满足: φ(u2)=φ(u)2, 则对所有的u,v∈J, 有 φ(uv)=φ(u)φ(v)或φ(uv)=φ(v)φ(u).

关键词: 质环, Jordan理想, 非挠环, 同态, Jordan同态, Jordan自同构

Abstract: The present paper proves the following result : Let R be a 2-torsion free prime ring, let J be a Jordan ideal and a subring of R. If φ: R→R is an automorphism satisfying φ(u2)=φ(u)2 for all u∈J, then φ(uv)=φ(u)φ(v) or φ(uv)=φ(v)φ(u) f or all u,v∈J.

Key words: prime ring, Jordan ideal, torsion free ring, homomorphism, Jordan homomorphism, Jordan automorphism
