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.

NON LINEAR EIGENVALUE PROBLEMS
Matemática Contemporânea, 2004 In this paper we consider generalized eigenvalue problems for a family of operators with a polynomial dependence on a complex parameter. This problem is equivalent to a genuine non self-adjoint operator. We discuss here existence of non trivial eigenstates for models coming from analytic theory of smoothness for P.D.E.

Blockchain Technology and the Circular Economy Transition: Associations With Company Performance
Business Strategy and the Environment, EarlyView.ABSTRACT The adoption of circular economy (CE) practices in the private sector has received increasing academic and managerial attention, although the implementation of such practices continues to face significant barriers. Among Industry 4.0 technologies, blockchain has been identified as a potential factor associated with the CE transition.

A Decision‐Making Model for Implementing Green Technology in Sustainable Building Projects
Business Strategy and the Environment, EarlyView.ABSTRACT Green technology (GT) adoption is pivotal for reconciling environmental stewardship with economic viability in the built environment, particularly in resource‐constrained emerging economies. However, empirical evidence on how specific GT drivers actively mitigate adoption barriers remains scarce.

Business Strategy and the Environment, EarlyView.ABSTRACT This study examines how plastics manufacturing firms can be classified according to their level of implementation of circular economy (CE) and industrial symbiosis (IS) practices and how such adoption influences sustainability performance. Using data from plastics manufacturing firms, we integrate cluster analysis with partial least squares ...

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.

Business Strategy and the Environment, EarlyView.ABSTRACT This study investigates the way sustainable innovation, conceptualized as a second‐order construct integrating sustainable orientation and innovation culture, impacts triple bottom line (TBL) performance. It also examines the mediating roles of product, process, organizational, and marketing innovations.

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 ...

Smart Cities Leading the Green Transition: Linking Open Innovation and Entrepreneurial Dynamics
Business Strategy and the Environment, EarlyView.ABSTRACT Smart cities today are vibrant spaces where technology, collaboration, and sustainability come together to shape a better future. The green transition in cities is not just about building greener infrastructure or cutting emissions. It also changes how people, institutions, and businesses think and act.

Levenberg-Marquardt Method for the Eigenvalue Complementarity Problem
The Scientific World Journal, 2014 The eigenvalue complementarity problem (EiCP) is a kind of very useful model, which is widely used in the study of many problems in mechanics, engineering, and economics.
