| 摘 要： | 设U是一个 2-无挠的三角代数,D ={dn}n∈N是U上一个Lie积为平方零元的非线性Jordan高阶可导映射。证明了三角代数U上的每一个Lie积为平方零元的非线性Jordan高阶可导映射都是高阶导子。作为结论的应用,得到套代数或 2-无挠的上三角分块矩阵代数上的每一个Lie积为平方零元的非线性Jordan高阶可导映射都是高阶导子。

| Abstract: | Let U be a 2-torsion free triangular algebra, D={dn}n∈N is a nonlinear Jordan higher derivable map on triangular algebra U by Lie product square zero elements. In this paper, it is shown that every nonlinear Jordan higher derivable map on triangular algebra U by Lie product square zero elements is a higher derivation. As its application, we get that every nonlinear Jordan higher derivable map on a nest algebra or a 2-torsion free block upper triangular matrix algebra U by Lie product square zero elements is a higher derivation. |
