摘要
设R是含有单位元的交换环,M n(R)是R上的所有n×n矩阵组成的R-模.论文介绍了M n(R)上(局部)左乘映射、(局部)右乘映射以及(局部)李映射的概念,并证明了M n(R)上的每个局部左乘映射(局部右乘映射、局部李映射)都是左乘映射(右乘映射、李映射).
Let R be a commutative ring with identity, Mn(R) is the R -module consisting of all n × n matrices over R. In this paper, we introduced the notions of (local) left multiplication maps, (local) right multiplication maps and (local) Lie maps on Mn(R) , and proved that every local left multiplication map (resp. , local right multiplication map, local Lie map) was a left multiplication map (resp. , right multiplication map, Lie map) of Mn(R) .
