Derived equivalences between generalized matrix algebras [PDF]

open access: yesCzechoslovak Mathematical Journal, 2019
For an algebra \(A\), \(\mathcal{D}(A)\) denotes the derived category of modules of \(A\). Let \(A_{i}\) (\(1\leq i\leq n\)) be a family of \(K\)-algebras and \(M_{ij}\) (\(1\leq i\leq n\), \(1\leq j\leq n\)) a family of \(A_{i}\)-\(A_{j}\)-bimodules such that \(M_{ii}=A_{i}\) for all \(i\), and let \(\Lambda\) the generalized matrix algebra \(\begin ...

On Amenability-Like Properties of a Class of Matrix Algebras

open access: yesJournal of Mathematics, 2022
In this study, we show that a matrix algebra ℒℳIpA is a dual Banach algebra, where A is a dual Banach algebra and 1≤p≤2. We show that ℒℳIpℂ is Connes amenable if and only if I is finite, for every nonempty set I.

Error analysis of the generalized low-rank matrix approximation

open access: yesThe Electronic Journal of Linear Algebra, 2021
In this paper, we propose an error analysis of the generalized low-rank approximation, which is a generalization of the classical approximation of a matrix $A\in\mathbb{R}^{m\times n}$ by a matrix of a rank at most $r$, where $r\leq\min\{m,n\}$.

Generalized Heisenberg–Virasoro algebra and matrix models from quantum algebra

open access: yesJournal of Mathematical Physics, 2023
In this paper, we construct the Heisenberg–Virasoro algebra in the framework of the R(p,q)-deformed quantum algebras. Moreover, the R(p,q)-Heisenberg–Witt n-algebras is also investigated. Furthermore, we generalize the notion of the elliptic Hermitian matrix models.

Cubic Matrix, Generalized Spin Algebra and Uncertainty Relation [PDF]

open access: yes, 2003
We propose a generalization of spin algebra using three-index objects. There is a possibility that a triple commutation relation among three-index objects implies a kind of uncertainty relation among their expectation values.Comment: Latex ...

Nonlinear Jordan Derivable Mappings of Generalized Matrix Algebras by Lie Product Square-Zero Elements

open access: yesJournal of Mathematics, 2021
The aim of the paper is to give a description of nonlinear Jordan derivable mappings of a certain class of generalized matrix algebras by Lie product square-zero elements.

Reliable Generation of High-Performance Matrix Algebra [PDF]

open access: yesACM Transactions on Mathematical Software, 2015
Scientific programmers often turn to vendor-tuned Basic Linear Algebra Subprograms (BLAS) to obtain portable high performance. However, many numerical algorithms require several BLAS calls in sequence, and those successive calls do not achieve optimal performance. The entire sequence needs to be optimized in concert.

Miscellaneous reverse order laws and their equivalent facts for generalized inverses of a triple matrix product

open access: yesAIMS Mathematics, 2021
Reverse order laws for generalized inverses of products of matrices are a class of algebraic matrix equalities that are composed of matrices and their generalized inverses, which can be used to describe the links between products of matrix and their ...

Quantum two-block group algebra codes [PDF]

open access: yesPhysical Review A, 2023
We consider quantum two-block group algebra (2BGA) codes, a previously unstudied family of smallest lifted-product (LP) codes. These codes are related to generalized-bicycle (GB) codes, except a cyclic group is replaced with an arbitrary finite group ...
