摘要：

In this note we consider representations of the Drazin inverse of 2 x 2 block matrices under conditions weaker than those used in recent papers on the subject, in particular in [D.S. Djordjevic, P.S. Stanimirovic, On the generalized Drazin inverse and generalized resolvent, Czechoslovak Math. J. 51 (126) (2001) 617-634; R. Hartwig, X. Li, Y. Wei, Representations for the Drazin inverse of 2 x 2 block matrix, SIAM J. Matrix Anal. Appl. 27 (2006) 757-771]. (C) 2008 Elsevier Inc. All rights reserved.
