Inverse Eigenvalue Problem of Unitary Hessenberg Matrices
Discrete Dynamics in Nature and Society, 2009 Let H∈ℂn×n be an n×n unitary upper Hessenberg matrix whose subdiagonal elements are all positive, let Hk be the kth leading principal submatrix of H, and let H˜k be a modified submatrix of Hk.

Asian Journal of Control, EarlyView.Abstract Large swarms often adopt a hierarchical network structure that incorporates information aggregation. Although this approach offers significant advantages in terms of communication efficiency and computational complexity, it can also lead to degradation due to information constraints.

Error analysis of householder transformations as applied to the standard and generalized eigenvalue problems [PDF]
Backward error analyses of the application of Householder transformations to both the standard and the generalized eigenvalue problems are presented. The analysis for the standard eigenvalue problem determines the error from the application of an exact ...

Modeling and parameter estimation for fractional large‐scale interconnected Hammerstein systems
Asian Journal of Control, EarlyView.Abstract This paper addresses the challenge of modeling and identifying large‐scale interconnected systems exhibiting memory effects, hereditary properties, and non‐local interactions. We propose a fractional‐order extension of the Hammerstein architecture that incorporates Grünwald–Letnikov operators to capture complex dynamics through multiple ...

Asian Journal of Control, EarlyView.Abstract The linear‐quadratic regulator (LQR) problem of optimal control of an uncertain discrete‐time linear system (DTLS) is revisited in this paper from the perspective of Tikhonov regularization. We show that an optimally chosen regularization parameter reduces, compared to the classical LQR, the values of a scalar error function, as well as the ...

On the Eigenvalue Problem for One-Dimensional Differential Operator with Nonlocal Integral Condition
Nonlinear Analysis, 2004 The article investigates the eigenvalue problem for ordinary onedimensional differential operator with nonlocal integral condition. Such a problem is met in the literature quite rarely and is considerably less investigated.

Matrix methods for radial Schr\"{o}dinger eigenproblems defined on a semi-infinite domain
, 2013 In this paper, we discuss numerical approximation of the eigenvalues of the one-dimensional radial Schr\"{o}dinger equation posed on a semi-infinite interval.

Business Strategy and the Environment, EarlyView.ABSTRACT Drawing on comparative institutional theory, we study the nature and magnitude of the effects of national environmental policies on corporate green innovation in developed versus emerging markets. Using a sample of 1831 listed firms in 34 countries from 2002 to 2020, we find that national environmental policies increase corporate green ...

Global bifurcation for semilinear eigenvalue problems involving nonlocal terms
Electronic Journal of Differential EquationsWe investigate global bifurcation phenomenon for a class of semilinear eigenvalue problems involving nonlocal terms. Under certain assumptions, we demonstrate the existence of a global continuum emanating from the first eigenvalue of the unperturbed ...
