La inversa de Moore-Penrose ponderada en el problema de mínimos cuadrados cuadrados ponderados en matrices EP-ponderadas

Hernández, Araceli Elisabet; Lattanzi, Marina Beatriz; Thome, Néstor (Asociación Argentina de Matemática Aplicada, Computacional e Industrial, 2013)

Se conoce que en la soluci´on aproximada (en norma 2) por m´ınimos cuadrados de un sistema de ecuaciones lineales inconsistente aparece la inversa generalizada de Moore-Penrose. En los casos en que se utilizan normas inducidas ...
On a partial order defined by the weighted Moore Penrose inverse

Hernández, Araceli Elisabet; Lattanzi, Marina Beatriz; Thome, Néstor (Elsevier, 2013-03-15)

The weighted Moore-Penrose inverse of a matrix can be used to define a partial order on the set of m x n complex matrices and to introduce the concept of weighted-EP matrices. In this paper we study the weighted star partial ...
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 ...
Órdenes parciales y pre-órdenes definidos a partir de matrices inversas generalizadas

Hernández, Araceli Elisabet (Universitat Politècnica de València, 2016-05-16)

[EN] Matrix Analysis and its applications are an important area of Applied Mathematics and are the basis of many industrial applications and for engineering in general. This work can be classified as being part of Matrix ...
Weighted binary relations involving the Drazin inverse

Hernández, Araceli Elisabet; Lattanzi, Marina Beatriz; Thome, Néstor (Elsevier, 2015-02)

[EN] The Drazin inverse of a matrix has been used in the literature to define a pre-order on the set of square complex matrices. In this paper we analyze new binary relations defined on the set of rectangular complex ...
