On the spectral norm of a doubly stochastic matrix and level-k circulant matrix

open access: yesSpecial Matrices
A simple proof using Birkhoff theorem is given for the result that the spectral norm of a doubly stochastic matrix is 1. We also show that the result generalizes the results of İpek, Bozkurt, and Jiang and Zhou on circulant matrices and rr-circulant ...

Norm inequalities for functions of matrices

open access: yesHeliyon
In this paper, we prove several spectral norm and unitarily invariant norm inequalities for matrices in which the special cases of our results present some known inequalities. Also, some of our results give interpolating inequalities which are related to

Consistency Analysis of Spectral Regularization Algorithms

open access: yesAbstract and Applied Analysis, 2012
We investigate the consistency of spectral regularization algorithms. We generalize the usual definition of regularization function to enrich the content of spectral regularization algorithms.

Consistency of the total least squares estimator in the linear errors-in-variables regression

open access: yesModern Stochastics: Theory and Applications, 2018
This paper deals with a homoskedastic errors-in-variables linear regression model and properties of the total least squares (TLS) estimator. We partly revise the consistency results for the TLS estimator previously obtained by the author [18]. We present

Some bounds for the spectral norms of some circulant matrices with generalized Jacobsthal–Lucas numbers

open access: yesMathematics Open
The purpose of this paper is to investigate the bounds of the spectral norms of some circulant matrices whose elements are a generalization of Jacobsthal–Lucas numbers called bi-periodic Jacobsthal–Lucas numbers by three different ways.

Spectral-Collocation Methods for Fractional Pantograph Delay-Integrodifferential Equations

open access: yesAdvances in Mathematical Physics, 2013
We propose and analyze a spectral Jacobi-collocation approximation for fractional order integrodifferential equations of Volterra type with pantograph delay. The fractional derivative is described in the Caputo sense. We provide a rigorous error analysis

Classification of Hyperspectral Images Using Kernel Fully Constrained Least Squares

open access: yesISPRS International Journal of Geo-Information, 2017
As a widely used classifier, sparse representation classification (SRC) has shown its good performance for hyperspectral image classification. Recent works have highlighted that it is the collaborative representation mechanism under SRC that makes SRC a ...
