Introducing two complementary novel algebraic operations: Matrix-separation and Matrices-joining for programming evaluation and development

open access: yesAin Shams Engineering Journal, 2020
In the last decade, many computer science disciplines have been manipulating large amounts of data like artificial neural networks, data recognition, data mining and big data.Recently, many programmers and application designers have relied on the ...

Quantum symmetry algebras of spin systems related to Temperley–Lieb R-matrices [PDF]

open access: yesJournal of Mathematical Physics, 2008
A reducible representation of the Temperley–Lieb algebra is constructed on the tensor product of n-dimensional spaces. One obtains as a centralizer of this action a quantum algebra (a quasitriangular Hopf algebra) Uq with a representation ring equivalent to the representation ring of the sl2 Lie algebra.

Index Reduction for Differential-algebraic Equations with Mixed Matrices [PDF]

open access: yesJournal of the ACM, 2017
Differential-algebraic equations (DAEs) are widely used for the modeling of dynamical systems. The difficulty in numerically solving a DAE is measured by its differentiation index.

Stability of quaternionic linear systems [PDF]

open access: yes, 2006
The main goal of this paper is to characterize stability and bounded-input-bounded-output (BIBO)-stability of quaternionic dynamical systems. After defining the quaternion skew-field, algebraic properties of quaternionic polynomials such as divisibility ...

Second-Order Multi-Reference Algebraic Diagrammatic Construction Theory for Photoelectron Spectra of Strongly Correlated Systems. [PDF]

open access: yesJournal of Chemical Theory and Computation, 2019
We present a second-order formulation of multi-reference algebraic diagrammatic construction theory [Sokolov, A. Yu. J. Chem. Phys. 2018, 149, 204113] for simulating photoelectron spectra of strongly correlated systems (MR-ADC(2)).

Applications of the Moore-Penrose Generalized Inverse to Linear Systems of Algebraic Equations

open access: yesAmerican Journal of Applied Mathematics, 2019
In this work, we consider linear systems of algebraic equations. These systems are studied utilizing the theory of the Moore-Penrose generalized inverse or shortly (MPGI) of matrices.
