    A weak group inverse for rectangular matrices 
    Ferreyra, David Eduardo; Orquera, V.; Thome, Néstor (Springer-Verlag, 2019-10)
    [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 ...

    On some new pre-orders defined by weighted Drazin inverses 
    Hernández, Araceli Elisabet; Lattanzi, Marina Beatriz; Thome Coppo, Néstor Javier (Elsevier, 2016-05-05)
    In this paper, we investigate new binary relations defined on the set of rectangular complex matrices based on the weighted Drazin inverse and give some characterizations of them. These relations become pre-orders and ...

    The W-weighted Drazin-star matrix and its dual 
    Zhou, Mengmeng; Chen, Jianlong; Thome, Néstor (University of Wyoming Libraries, 2021-02-03)
    [EN] After decades studying extensively two generalized inverses, namely Moore--Penrose inverse and Drazin inverse, currently, we found immersed in a new generation of generalized inverses (core inverse, DMP inverse, etc.). ...

    Weighted G-Drazin inverses and a new pre-order on rectangular matrices 
    Coll, Carmen; Lattanzi, Marina; Thome, Néstor (Elsevier, 2018)
    [EN] This paper deals with weighted G-Drazin inverses, which is a new class of matrices introduced to extend (to the rectangular case) G-Drazin inverses recently considered by Wang and Liu for square matrices. First, we ...
