The generalized Drazin inverse with commutativity up to a factor in a Banach algebra
, 2009 In this paper, we investigate an explicit representation of the generalized Drazin inverse (a±b)d in terms of a,ad,b and bd under the condition ab=λba or ab=aba and extend to Banach algebras recent results of C.Y ...

On the generalized Drazin inverse in a Banach algebra
, 2019 [EN] We give the representations of (a + b)(d), (a + ab)(d) and (a + ba)(d) in terms of a, b, a(d) and b(d) being elements of a Banach algebra with a(3)b = ba and b(3)a = ab. We also give the representations of (a + b)(d) under the assumptions a(3)b = ba, parallel to a(D)b parallel to < 1 , and parallel to(1 - aa(D))b(D)a parallel to < 1.

Iterative Methods for the Drazin Inverse of a Matrix With a Complex Spectrum
, 2004 Iterative methods for the Drazin inverse of a square matrix with a real spectrum have been developed recently. These methods are generalized in the case of matrices with complex spectra.

Minimal rank weighted weak Drazin inverses
The concept of a minimal rank weak Drazin inverse for square matrices is extended to rectangular matrices. Precisely, a minimal rank weighted weak Drazin inverse is introduced and its properties are investigated.

DFT calculation of the generalized and drazin inverse of a polynomial matrix
, 2008 A new algorithm is presented for the determination of the generalized inverse and the drazin inverse of a polynomial matrix. The proposed algorithms are based on the discrete Fourier transform and thus are computationally fast in contrast to other known ...
