Consistency in Positive Reciprocal Matrices: An Improvement in Measurement Methods

open access: yesIEEE Access, 2018
Consistency estimation of decision-makers' judgments in decision-making processes is fundamental to generating agreements and making decisions. Analytic hierarchy process (AHP) is a widely used method to solve this type of problem, enabling evaluation of

A parameterized shift-splitting preconditioner for saddle point problems

open access: yesMathematical Biosciences and Engineering, 2019
Recently, Chen and Ma [A generalized shift-splitting preconditioner for saddle point problems, Applied Mathematics Letters, 43 (2015) 49-55] introduced a generalized shift-splitting preconditioner for saddle point problems with symmetric positive ...

Mesoscopic eigenvalue statistics of Wigner matrices [PDF]

open access: yes, 2016
We prove that the linear statistics of the eigenvalues of a Wigner matrix converge to a universal Gaussian process on all mesoscopic spectral scales, i.e.

An integro-differential inequality related to the smallest positive eigenvalue of p(x)-Laplacian Dirichlet problem

open access: yesAnnales Universitatis Paedagogicae Cracoviensis: Studia Mathematica, 2016
We consider the eigenvalue problem for the p(x)-Laplace - Beltrami operator on the unit sphere. We prove an integro - differential inequality related to the smallest positive eigenvalue of this problem.

Phase transition of the largest eigenvalue for nonnull complex sample covariance matrices [PDF]

open access: yes, 2004
We compute the limiting distributions of the largest eigenvalue of a complex Gaussian samplecovariance matrix when both the number of samples and the number of variables in each samplebecome large.

Analytical solutions to some generalized and polynomial eigenvalue problems

open access: yesSpecial Matrices, 2021
It is well-known that the finite difference discretization of the Laplacian eigenvalue problem −Δu = λu leads to a matrix eigenvalue problem (EVP) Ax =λx where the matrix A is Toeplitz-plus-Hankel.

Further generalization of symmetric multiplicity theory to the geometric case over a field

open access: yesSpecial Matrices, 2021
Using the recent geometric Parter-Wiener, etc. theorem and related results, it is shown that much of the multiplicity theory developed for real symmetric matrices associated with paths and generalized stars remains valid for combinatorially symmetric ...
