RECTANGULAR INPUT-OUTPUT MODELS BY MOORE-PENROSE INVERSE

open access: yesRect@, 2014
The official available data must be the primary datasource in economic studies. However, in economic modelling related with supply-use tables this aspect is ignored.

Extensions of pseudo-Perron-Frobenius splitting related to generalized inverse AT,S(2)

open access: yesSpecial Matrices, 2018
We in this paper define the outer-Perron-Frobenius splitting, which is an extension of the pseudo- Perron-Frobenius splitting defined in [A.N. Sushama, K. Premakumari, K.C.

Smoothed Analysis of Moore-Penrose Inversion

open access: yes, 2010
We perform a smoothed analysis of the condition number of rectangular matrices. We prove that, asymptotically, the expected value of this condition number depends only of the elongation of the matrix, and not on the center and variance of the underlying probability distribution.

On an inequality related to the volume of a parallelepiped

open access: yesExamples and Counterexamples
The problem of establishing an upper bound for the volume of a parallelepiped is considered by utilizing an original approach involving a skew-symmetric matrix of order four (along with its Moore–Penrose inverse).

On the Moore-Penrose inverse in $C^*$-algebras

open access: yes, 2013
In this article, two results regarding the Moore-Penrose inverse in the frame of $C^*$-algebras are considered. In first place, a characterization of the so-called reverse order law is given, which provides a solution of a problem posed by M. Mbekhta.
