Determinantal representation of weighted generalized inverses
\textit{D.~W. Robinson} [Linear Algebra Appl. 411, 254--276 (2005; Zbl 1086.15500)] studied the Moore-Penrose inverse of a matrix in a commutative ring and gave a determinantal formula for the Moore-Penrose inverse. The authors of the present paper introduce some determinantal representations of the weighted generalized inverse by using a result of the paper above. They also present a method for computing minors of the weighted Moore-Penrose inverse and the W-weighted Drazin inverse.
