在本文中,我们考虑两个矩阵之和的 Drazin 逆,并在比最近一些有关该主题的论文中使用的条件更弱的条件下推导加法公式。作为推论,我们从 Yang 和 Liu 的论文中得到了主要结果 [H. Yang, X. Liu,两个矩阵之和的 Drazin 逆及其应用,J. Comput。应用。数学。 235(2011)1412–1417]。作为一个应用,我们给出了块矩阵的 Drazin 逆的一些新表示。
In this paper, we consider the Drazin inverse of a sum of two matrices and derive additive formulas under conditions weaker than those used in some recent papers on the subject. As a corollary we get the main results from the paper of Yang and Liu [H. Yang, X. Liu, The Drazin inverse of the sum of two matrices and its applications, J. Comput. Appl. Math. 235 (2011) 1412–1417]. As an application we give some new representations for the Drazin inverse of a block matrix.
