INTERVAL ITERATIVE METHODS FOR COMPUTING MOORE-PENROSE INVERSE ∗

, 2008
In this paper, we import interval method to the iteration for computing Moore-Penrose inverse of the full row (or column) rank matrix. Through modifying the classical Newton iteration by interval method, we can get better numerical results.

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

, 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.

Extending the Moore-Penrose inverse

Filomat, 2016
We show that it is possible to define generalized inverse similar to the Moore-Penrose inverse by slightly modified Penrose equations. Then we are Investigating properties of this, so-called extended Moore-Penrose inverse.

On the covariance of the Moore-Penrose inverse

Linear Algebra and its Applications, 1983
AbstractIt is readily seen that the Moore-Penrose inverse A+ of a singular square matrix A does not for all regular matrices T satisfy the covariance condition (TAT−1)+ = TA+T−1. Thus the problem arises to describe the class C(A) of all those matrices T for which this condition is valid. The problem is solved for all matrices A of rank one and two.

New Bounds for the Davis–Wielandt Radius via the Moore–Penrose Inverse of Bounded Linear Operators

Axioms
In this paper, we obtain some new upper bounds involving powers of the Davis–Wielandt radius of bounded linear operators with closed ranges by using the Moore–Penrose inverse.

An Investigation on Mathematical Modeling of Operators on The Hilbert Domain subjected to The Equality Theory

Journal of Applied Science and Engineering
This work begins by presenting the essential and enough circumstances for the presence of the Hermitian solution to equations ΨXΦ + Φ∗YΨ∗ = Ω = Ψ∗XΦ∗+ ΦYΨ in the case where the operators are linear and bounded in a Hilbert space and in terms of the Moore-

RECTANGULAR INPUT-OUTPUT MODELS BY MOORE-PENROSE INVERSE

Rect@, 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.
