Bound for the largest singular value of nonnegative rectangular tensors

Open Mathematics, 2016
In this paper, we give a new bound for the largest singular value of nonnegative rectangular tensors when m = n, which is tighter than the bound provided by Yang and Yang in “Singular values of nonnegative rectangular tensors”, Front. Math.

Multigrid waveform relaxation on spatial finite element meshes: The discrete-time case [PDF]

, 1996
. The waveform relaxation method and its multigrid acceleration are studied as solution procedures for the system of ordinary differential equations obtained by finite element discretisation of a linear parabolic initial boundary value problem.

On Remotest set and Random controls in Kaczmarz algorithm

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2018
In this paper we analyse the Kaczmarz projection algorithm with Remotest set and Random control of projection indices and provide a suficient condition such that each projection index appears infinitely many times during the iterations.

Geršhgorin-type theorems for Z1-eigenvalues of tensors with applications

Demonstratio Mathematica
In this article, we present several Geršhgorin-type theorems for Z1{Z}_{1}-eigenvalues of tensors, which improve the results provided by Wang et al. (Some upper bounds on Zt{Z}_{t}-eigenvalues of tensors, Appl. Math. Comput.

Distributive and Dual Distributive Elements in Hyperlattices

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2017
In this paper we introduce and study distributive elements, dual distributive elements in hyperlattices, and prove that these elements forms ∧-semi lattice and ∨-semi hyperlattice, respectively.

Prime filters of hyperlattices

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2016
The purpose of this paper is the study of prime ideals and prime filters in hyperlattices. I-filter and the filter generated by a ∈ L are introduced. Moreover, we introduce dual distributive hyperlattices, and I-filter in dual distributive hyperlattices.

Improved modified gradient-based iterative algorithm and its relaxed version for the complex conjugate and transpose Sylvester matrix equations

Demonstratio Mathematica
In this article, we present two new algorithms referred to as the improved modified gradient-based iterative (IMGI) algorithm and its relaxed version (IMRGI) for solving the complex conjugate and transpose (CCT) Sylvester matrix equations, which often ...

A parallel multiparametric Gauss-Seidel method

, 2006
In this paper we consider the local Modified Extrapolated Gauss-Seidel(LMEGS) method combined with Semi-Iterative techniques for the numerical solution of the Convection Diffusion equation and compare it with the local SOR method. Subject classification :
