讨论素环上的一类中心化子的保持性问题.证明了素环上的左Jordanτ-中心化子是左τ-中心化子,并进一步证明了素环上的Jordanτ-中心化子是τ-中心化子,从而在素环上得到了一个良好的保持性结论.
A kind of centralizers keeping problem on prime rings is discussed.It is proved that in some conditions left Jordan τ-centralizers are left τ-centralizers on prime rings,moreover Jordan τ-centralizers are τ-centralizers on prime rings.Thus a good mapping keeping conclusion on prime rings is obtained.
