摘要:

运用矩阵分块方法研究三角代数上的一类非线性可交换映射: 模线性可交换映射. 刻画了此类映射的具体形式, 给出了三角代数上模线性可交换映射是真可交换映射的充分条件, 并证明了套代数上的每个模线性可交换映射都是真可交换映射.

关键词: 三角代数, 可交换映射, 模线性映射

Abstract:

The authors studied a class of nonlinear  commuting maps (namely, modulo linear commuting map) on triangular algebras, described the forms of such maps, and gave such a sufficient condition that every modulo linear commuting map on triangular algebras is proper. As an application, it is proved that every modulo linear commuting map on nest algebras is proper.

Key words: triangular algebra, commuting map, modulo linear map
