    Further properties on the core partial order and other matrix partial orders 
    Malik, Saroj B.; Rueda, Laura Catalina; Thome, Néstor (Taylor & Francis, 2014-12-02)
    This paper carries further the study of core partial order initiated by Baksalary and Trenkler [Core inverse of matrices, Linear Multilinear Algebra. 2010;58:681-697]. We have extensively studied the core partial order, ...

    Nilpotent matrices and the minus partial order 
    Gareis, María Inés; Lattanzi, Marina; Thome, Néstor (Informa UK (National Inquiry Services Center), 2017)
    [EN] In this paper, {1}-inverses of a nilpotent matrix as well as matrices above a given nilpotent matrix under the minus partial order are characterized.

    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 diamond partial order in rings 
    Lebtahi Ep-Kadi-Hahifi, Leila; Patricio, Pedro; Thome, Néstor (Taylor & Francis: STM, Behavioural Science and Public Health Titles, 2014)
    In this paper we introduce a new partial order on a ring, namely the diamond partial order. This order is an extension of a partial order defined in a matrix setting in [J.K. Baksalary and J. Hauke, A further algebraic ...

    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 ...
