1. A weak group inverse for rectangular matrices

Author

Ferreyra, D., Orquera, V., and Thome, N.

Abstract

In this paper, we extend the notion of weak group inverse to rectangular matrices (called W-weighted WG inverse) by using the weighted core EP inverse recently investigated. This new generalized inverse also generalizes the well-known weighted group inverse given by Cline and Greville. In addition, we give several representations of the W-weighted WG inverse, and derive some characterizations and properties.
