摘要 研究了两个矩阵和的Drazin逆的表示,根据一个分块矩阵拆分为两个三角矩阵的思想,利用Drazin逆的相关性质,给出了两个矩阵的和在一定条件下Drazin逆的表示,推广已有结果。 In this paper,we obtain representations for the Drazin inverses of the sum of two matrices. According to thinking of a block matrix split into two triangular matrices,the different prove of the representations for Drazin inverse of the sum of two matrices were given using the property of Drazin inverse.
