A comment on some recent results concerning the Drazin inverse of an anti-triangular block matrix
Yuan Deng · Filomat · 2012
In this note we give formulae for the Drazin inverseMD of an anti-triangular special block matrix M = (ABC0)under some conditions expressed in terms of the individual blocks, which generalize some recent results given by Changjiang Bu [7, 8] and Chongguang Cao [10], etc.
