摘要
设R(≠F_3)是特征不为2的交换主理想整环,M_n(R)定义R上的n×n矩阵模,本文刻划当n≥m时从M_n(R)到M_n(R)的保持立方幂等矩阵的线性映射的形式,由此推广了Chan和Lim的一个结果([1,定理3]).
Let R be a commutative principal ideal domain of characteristic ≠2 and R ≠ F_3,and let M_n(R) be the n × n matrix module over R. We determine the forms of R -linear maps,from M_n(R) to M_m(R),which preserve tripotent matrices when n ≥ m,thereby extending .one of Chan and Lim's result (see [1,Th3]).
