特征3的域上保矩阵Moore-Penrose逆的可逆线性变换

Linear Transformations Preserving M-P Inverses of Matrices over Fields of Characteristic 3

设Ｆ是一个特征３的域，Ｍｎ（Ｆ）记Ｆ上所有ｎ阶方阵所形成的线性空间。刻划了Ｍｎ（Ｆ）上保矩阵Ｍｏｏｒｅ－Ｐｅｎｒｏｓｅ逆的可逆线性变换的结构。

Let F be a field of characteristic 3 and M n (F) the linear space of all n×n matrices over F.The structure of nonsingular linear transformations on M n (F) was preserved the M P inverses of matrices.
