| Abstract: |
| In this paper, we study the representations of the Drazin inverse of a modified matrix A-CB. By the properties of the k-idempotent matrix and the diagonalizable matrix, we get some new representations of the Drazin inverse through weakened conditions of literature [4]. |
| Key words: modified matrix Drazin inverse Schur complement |
