三角代数上恒等算子处的Jordan可导映射

摘要

In this paper, the authors introduced derivation, Jordan derivable map and triangular algebra, discussed the relationship between the two maps, and finally, obtained that each Jordan derivable map at the unit on triangular algebra was a derivation.%介绍了导子、Jordan 可导映射、三角代数的概念,分析讨论了两种映射之间的关系,推导出了三角代数上的每个恒等算子处的 Jordan 可导映射都是导子的结论.
