Chapter Chapter 4 in Algebraic Theory of Generalized Inverses, 2024, pp 143-208 from Springer

Abstract: Abstract For complex matrices, we know from Chap. 3 that the group inverse only exists for matrices with index no more than 1, so it is not suitable for the more common class of matrices whose index exceed 1. In this chapter, we introduce the Drazin inverse which is a slight generalization of the group inverse.
