WEIGHTED DRAZIN INVERSE OF A MODIFIED MATRIX
Tanja Totic · Functional Analysis, Approximation and Computation · 2014
We present conditions under which the weighted Drazin inverse of a modified matrix A-CWD d,W WB can be expressed in terms of the weighted Drazin inverse of A and it’s generalized Schur complement D-BWA d,W WC. The results extend the earlier works about the Drazin inverse.
