On the eigenstructure of the $q$-Durrmeyer operators

Turkish Journal of Mathematics, 2023
The purpose of this paper is to establish the eigenvalues and the eigenfunctions of both the $q$-Durrmeyer operators $D_{n,q}$ and the limit $q$-Durrmeyer operators $D_{\infty,q}$ introduced by V. Gupta in the case 0<$q$<1. All moments for $D_{n,q}$ and $D_{\infty,q}$ are provided.

Impact of sample size on principal component analysis ordination of an environmental data set: effects on eigenstructure

Ekológia (Bratislava), 2016
In this study, we used bootstrap simulation of a real data set to investigate the impact of sample size (N = 20, 30, 40 and 50) on the eigenvalues and eigenvectors resulting from principal component analysis (PCA).

Matrix Polynomials with Completely Prescribed Eigenstructure [PDF]

SIAM Journal on Matrix Analysis and Applications, 2015
We present necessary and sufficient conditions for the existence of a matrix polynomial when its degree, its finite and infinite elementary divisors, and its left and right minimal indices are prescribed. These conditions hold for arbitrary infinite fields and are determined mainly by the "index sum theorem," which is a fundamental relationship between

Robust eigenstructure assignment in geometric control theory [PDF]

, 2014
In this paper we employ the Rosenbrock system matrix pencil for the computation of output-nulling subspaces of linear time-invariant systems which appear in the solution of a large number of control and estimation problems.

Robust $H_{\infty}$ Interval Observer for Linear Systems With a Controllable Convergence Rate: A Parametric Method

IEEE Access, 2019
In this paper, the design method of a robust interval observer for linear systems with time-varying disturbances is proposed. First, the H∞ gain performance is established by constructing the transfer function from disturbances to error dynamic ...
