What Do You Mean by “Nonlinear Eigenvalue Problems”?

open access: yesAxioms, 2018
A nonlinear eigenvalue problem is generally described by an equation of the form F(λ,x)=0, where F(λ,0)=0 for all λ, and contains by definition two unknowns: the eigenvalue parameter λ and the “nontrivial” vector(s)

Time Dependent Resonance Theory [PDF]

open access: yes, 1998
An important class of resonance problems involves the study of perturbations of systems having embedded eigenvalues in their continuous spectrum. Problems with this mathematical structure arise in the study of many physical systems, e.g.

An integral method for solving nonlinear eigenvalue problems

open access: yes, 2010
We propose a numerical method for computing all eigenvalues (and the corresponding eigenvectors) of a nonlinear holomorphic eigenvalue problem that lie within a given contour in the complex plane.

Dynamics of Controlled Hybrid Systems of Aerial Cable-Ways

open access: yes, 2006
Dynamics of the hybrid systems of aerial cable-ways is investigated. The eigenvalue problems are considered for such hybrid systems with different assumptions. An overview of different methods for eigenvalue problems is given. In the research, the method

Positive Solutions of Nonlinear Elliptic Eigenvalue Problems [PDF]

open access: yes, 1970
We shall study a class of mildly nonlinear elliptic eigenvalue problems which are suggested by several recently occurring problems concerning the steady state temperature distribution of a physical medium in which heat is being generated ...

On the second eigenvalue of nonlinear eigenvalue problems

open access: yesElectronic Journal of Differential Equations, 2018
This article is devoted to the characterization of the second eigenvalue of nonlinear eigenvalue problems. We propose an abstract approach which allows to treat nonsmooth quasilinear problems and also to recover, in a unified way, previous results ...

Existence Theorems for Some Classes of Boundary Value Problems Involving the P(X)-Laplacian

open access: yesNonlinear Analysis, 2008
We prove an alternative for a nonlinear eigenvalue problem involving the p(x)-Laplacian and study a subcritical boundary value problem for the same operator.

Chebyshev interpolation for nonlinear eigenvalue problems [PDF]

open access: yes, 2018
This work is concerned with numerical methods for matrix eigenvalue problems that are nonlinear in the eigenvalue parameter. In particular, we focus on eigenvalue problems for which the evaluation of the matrix-valued function is computationally ...

FEAST eigensolver for nonlinear eigenvalue problems [PDF]

open access: yesJournal of Computational Science, 2018
The linear FEAST algorithm is a method for solving linear eigenvalue problems. It uses complex contour integration to calculate the eigenvectors whose eigenvalues that are located inside some user-defined region in the complex plane. This makes it possible to parallelize the process of solving eigenvalue problems by simply dividing the complex plane ...
