Representations of the weighted WG inverse and a rank equation's solution. Issue 2 (22nd January 2023) - Ferreyra, D. E.
Abstract : In this paper, we present several representations of the W -weighted WG inverse. These representations are expressed in terms of matrix powers as well as in terms of matrix products involving only the Moore–Penrose inverse. In addition, a new characterization of the W -weighted WG inverse is presented by using a rank equation.
