Further Results on Weighted Core-EP Inverse of Matrices [PDF]

open access: yesResults in Mathematics, 2020
In this paper, we introduce the notation of $E$-weighted core-EP and $F$-weighted dual core-EP inverse of matrices. We then obtain a few explicit expressions for the weighted core-EP inverse of matrices through other generalized inverses. Further, we discuss the existence of generalized weighted Moore-Penrose inverse and additive properties of the ...

Bordering method to compute Core-EP inverse

open access: yesSpecial Matrices, 2018
Abstract Following the work of Kentaro Nomakuchi[10] and Manjunatha Prasad et.al., [7] which relate various generalized inverses of a given matrix with suitable bordering,we describe the explicit bordering required to obtain core-EP inverse, core-EP generalized inverse.

The Core-EP, Weighted Core-EP Inverse of Matrices and Constrained Systems of Linear Equations

open access: yesCommunications in Mathematical Research, 2021
We study the constrained system of linear equations$Ax=b$, $x∈\mathcal{R}(A^k)$for  $A ∈ \mathbb{C}^{n×n}$  and  $b ∈\mathbb{C}^n$, $k=Ind(A)$. When the system is consistent, it is well known that it has a unique $A^Db$. If the system is inconsistent, then we seek for the least squares solution of the problem and consider$$\min _{x \in \mathcal{R}\left(

Continuity of the core-EP inverse and its applications [PDF]

open access: yesLinear and Multilinear Algebra, 2019
In this paper, firstly we study the continuity of the core-EP inverse without explicit error bounds by virtue of two methods. One is the rank equality, followed from the classical generalized inverse. The other one is matrix decomposition. The continuity of the core inverse can be derived as a particular case. Secondly, we study perturbation bounds for

Fuzzy linear systems and core-EP inverses

open access: yes, 2021
The main purpose of this paper is to provide a solution of the consistent fuzzy linear system and a generalized solution of the inconsistent fuzzy linear system involving the core-EP inverse of an associated matrix. Before this can be achieved, it is necessary to study the block structure of the core-EP inverse.

Weighted binary relations involving core-EP inverse [PDF]

open access: yesFrontiers of Mathematics in China, 2020
Let \(A\in \mathbb{C}^{m \times n}\) and \(0 \neq W\in \mathbb{C}^{n \times m}\). Let \(k\) denote the minimum of the indices of the matrices \(AW\) and \(WA\) (the index of a matrix \(B\) is the smallest nonnegative integer \(k\) such that the ranks of \(B^k\) and \(B^{k+1}\) are the same).

Dual Core-EP Generalized Inverse and Decomposition

open access: yesCoRR
In this work, we introduce a new type of generalized inverse called dual core-EP generalized inverse (in short DCEPGI) for dual square matrices. We analyze the existence and uniqueness of the DCEPGI inverse and its compact formula using dual Drazin and dual MP inverse. Moreover, some characterizations using core-EP decomposition are obtained.

The $w$-core–EP inverse in rings with involution

open access: yesRevista de la Unión Matemática Argentina
Summary: The main goal of this paper is to present two new classes of generalized inverses in order to extend the concepts of the (dual) core-EP inverse and the (dual) \(w\)-core inverse. Precisely, we introduce the \(w\)-core-EP inverse and its dual for elements of a ring with involution.
