The representation and approximation of the Drazin inverse of a linear operator in Hilbert space
Abstract
We present a unified representation theorem for the Drazin inverse of linear operators in Hilbert space and a general error bound. Five specific expressions, computational procedures, and their error bounds for the Drazin inverse are uniformly derived from the unified representation theorem.
