Οƒ-derivations on generalized matrix algebras

open access: yesAnalele Universitatii "Ovidius" Constanta - Seria Matematica, 2020
Let 𝒭 be a commutative ring with unity, π’œ, 𝒝 be 𝒭-algebras, 𝒨 be (π’œ, 𝒝)-bimodule and 𝒩 be (𝒝, π’œ)-bimodule. The 𝒭-algebra 𝒒 = 𝒒(π’œ, 𝒨, 𝒩, 𝒝) is a generalized matrix algebra defined by the Morita context (π’œ, 𝒝, 𝒨, 𝒩, ξ𝒨𝒩, Ω𝒩𝒨).

Jordan Derivations and Antiderivations of Generalized Matrix Algebras [PDF]

open access: yesOperators and Matrices, 2012
Let $\mathcal{G}=[A & M N & B]$ be a generalized matrix algebra defined by the Morita context $(A, B,_AM_B,_BN_A, \Phi_{MN}, \Psi_{NM})$. In this article we mainly study the question of whether there exist proper Jordan derivations for the generalized ...

Local Lie derivations of generalized matrix algebras

open access: yesAIMS Mathematics, 2023
In this paper, we investigate local Lie derivations of a certain class of generalized matrix algebras and show that, under certain conditions, every local Lie derivation of a generalized matrix algebra is a sum of a derivation and a linear central-valued

Color Image Recovery Using Generalized Matrix Completion over Higher-Order Finite Dimensional Algebra [PDF]

open access: yesAxioms, 2023
To improve the accuracy of color image completion with missing entries, we present a recovery method based on generalized higher-order scalars. We extend the traditional second-order matrix model to a more comprehensive higher-order matrix equivalent ...

Lie $ n $-centralizers of generalized matrix algebras

open access: yesAIMS Mathematics, 2023
<abstract><p>In this paper, we introduce the notion of Lie $ n $-centralizers. We then give a description of Lie $ n $-centralizers on a generalized matrix algebra and present the necessary and sufficient conditions for a Lie $ n $-centralizer to be proper.

Οƒ-centralizers of generalized matrix algebras

open access: yesMiskolc Mathematical Notes, 2023
. In the present paper, we characterize Lie (Jordan) Οƒ -centralizers of generalized matrix algebras. More precisely, we obtain some conditions under which every Lie Οƒ -centralizer of a generalized matrix algebra can be expressed as the sum of a Οƒ ...

Generalized Matrix Algebras [PDF]

open access: yesCanadian Journal of Mathematics, 1955
The algebras considered here arose in the investigation of an algebra connected with the orthogonal group. We consider an algebra of dimension mn over a field K of characteristic zero, and possessing a basis {eij} (1 ≀ i ≀ m; 1 ≀ j ≀ n) with the multiplication property1,The field elements Ο•ij form a matrix Ξ¦ = (Ο•ij) of order n Γ— m.

The Generalized Matrix Chain Algorithm [PDF]

open access: yesIEEE/ACM International Symposium on Code Generation and Optimization, 2018
In this paper, we present a generalized version of the matrix chain algorithm to generate efficient code for linear algebra problems, a task for which human experts often invest days or even weeks of works.

Some matrix properties preserved by generalized matrix functions

open access: yesSpecial Matrices, 2019
Generalized matrix functions were first introduced in [J. B. Hawkins and A. Ben-Israel, Linear and Multilinear Algebra, 1(2), 1973, pp. 163-171]. Recently, it has been recognized that these matrix functions arise in a number of applications, and various ...
