Norm Properties of $S$-Universal Operators

Communications in Advanced Mathematical Sciences, 2020
We investigate the norm properties of a generalized derivation on a norm ideal $\mathcal{J}$ in $\mathcal{B}(H)$, the algebra of bounded linear operators on a Hilbert space $H$.

Chaos Control in Three Dimensional Cancer Model by State Space Exact Linearization Based on Lie Algebra

Mathematics, 2016
This study deals with the control of chaotic dynamics of tumor cells, healthy host cells, and effector immune cells in a chaotic Three Dimensional Cancer Model (TDCM) by State Space Exact Linearization (SSEL) technique based on Lie algebra.

Rayleigh-Quotient Representation of the Real Parts, Imaginary Parts, and Moduli of the Eigenvalues of General Matrices

Journal of Mathematical Sciences and Modelling, 2020
In the present paper, formulas for the Rayleigh-quotient representation of the real parts, imaginary parts, and moduli of the eigenvalues of general matrices are obtained that resemble corresponding formulas for the eigenvalues of self-adjoint matrices ...

Improved singular value inclusion sets for rectangular tensors

Journal of Inequalities and Applications
In this paper, improved singular value inclusion sets for rectangular tensors are given, which are tighter than those in (Zhao and Li in Linear Multilinear Algebra 66(7):1333–1350, 2018).

Cost Function Approach for Dynamical Component Analysis: Full Recovery of Mixing and State Matrix

Automation
A reformulation of the dynamical component analysis (DyCA) via an optimization-free approach is presented. The original cost function approach is converted into a numerical linear algebra problem, i.e., the computation of coupled singular-value ...

Antireflective Boundary Conditions for Deblurring Problems

Journal of Electrical and Computer Engineering, 2010
This survey paper deals with the use of antireflective boundary conditions for deblurring problems where the issues that we consider are the precision of the reconstruction when the noise is not present, the linear algebra related to these boundary ...
