Integral representation of the \(W\)-weighted Drazin inverse
Two integral representations are presented for the W-weighted Drazin inverse \(A_{D,W}\) of rectangular matrices \(A,W\). The first one has some restriction on the eigenvalues of \(AW\) or \(WA\) while the second one holds without any restriction on the eigenvalues.
