Título: A weak group inverse for rectangular matrices
Autor: Ferreyra, David Eduardo; Orquera, V.; Thome, Néstor
Resumen: [EN] In this paper, we extend the notion of weak group inverse to rectangular matrices (called WweightedWGinverse) 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.
