矩阵和Drazin逆的表示

The representation for the Drazin inverse of the sum of matrices

针对矩阵和Drazin逆的表示,由Drazin逆的定义,根据矩阵拆分的思想,利用Drazin逆的相关引理,给出了2个矩阵的和在一定条件下Drazin逆新的表示.新结果推广了已有的结果.

Aim at the representation for the Drazin inverse of the sum of matrices,by the definition of the Drazin inverse,according to thinking of matrix splitting,the new representation for the Drazin inverse of the sum of two matrices is given under certain conditions using relevant lemmas of Drazin inverse.The new result generalizes existing result.
