Existence and Uniqueness of Weighted Pseudoinverses with Nonsingular Indefinite Weights

Abstract

For arbitrary complex matrices, necessary and sufficient conditions for the existence and uniqueness of weighted pseudoinverses with nonsingular indefinite weights are obtained. The representations of these matrices are obtained in terms of the coefficients of characteristic polynomials of the Hermitizable matrices.
