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 ...

Block-encoding dense and full-rank kernels using hierarchical matrices: applications in quantum numerical linear algebra [PDF]

open access: yesQuantum, 2022
Many quantum algorithms for numerical linear algebra assume black-box access to a block-encoding of the matrix of interest, which is a strong assumption when the matrix is not sparse.

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.

The application of the orthogonal decomposition method for the algebraic solver separator

open access: yesВісник Харківського національного університету імені В.Н. Каразіна. Серія: Математичне моделювання, інформаційні технології, автоматизовані системи управління, 2022
The method which is valid for improving the transmission of information and a clean separation of signal and noise is suggested in [1]. The basis of the proposed new way of developing the theory and methods of communication is the rejection of the ...

New aspects of two Hessian-Riemannian metrics in plane [PDF]

open access: yesSurveys in Mathematics and its Applications, 2020
Due to the importance of Hessian structures we express some algebraic and geo\-me\-tric features of two such semi-Riemannian metrics in dimension two. For this purpose we use the separable coordinate systems of the Euclidean plane. Several properties are
