| Abstract: | The weighted Drazin inverses of matrices over rings is discussed. Some necessary and sufficient conditions for the weighted Drazin inverse to exist for the matrix over a ring and some necessary and sufficient conditions for the weighted Drazin inverses to exist for all matrices over a ring are given. |
