Global Bifurcation of Fourth-Order Nonlinear Eigenvalue Problems’ Solution

open access: yesInternational Journal of Differential Equations, 2021
In this paper, we study the global bifurcation of infinity of a class of nonlinear eigenvalue problems for fourth-order ordinary differential equations with nondifferentiable nonlinearity.

Isoperimetric inequalities for some nonlinear eigenvalue problems

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2004
In this paper we intend to review many of the known inequalities for eigenvalues of the Laplacian in Euclidean plane. Our aim is to show that we can generalize some results for the pseudo-Laplacian.

Nonlinear Eigenvalue Problems [PDF]

open access: yesBulletin of the Australian Mathematical Society, 1975
Eigenvalue problems with a nonlinear parameter are considered. The eigenvalue problem is a mapping T of the real axis into the symmetric operators on a Hilbert space together with a functional p on this space which generalizes the Rayleigh quotient in linear problems.

On the Variational Eigenvalues Which Are Not of Ljusternik-Schnirelmann Type

open access: yesAbstract and Applied Analysis, 2012
We discuss nonlinear homogeneous eigenvalue problems and the variational characterization of their eigenvalues. We focus on the Ljusternik-Schnirelmann method, present one possible alternative to this method and compare it with the Courant-Fischer ...

Nonlinear eigenvalue problems for higher order Lidstone boundary value problems

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2000
In this paper, we consider the Lidstone boundary value problem $y^{(2m)}(t) = \lambda a(t)f(y(t), \dots, y^{(2j)}(t), \dots y^{(2(m-1))}(t), 0 < t < 1, y^{(2i)}(0) = 0 = y^{(2i)}(1), i = 0, ..., m - 1$, where $(-1)^m f > 0$ and $a$ is nonnegative. Growth

Finite difference approximation of electron balance problem in the stationary high-frequency induction discharges

open access: yesMATEC Web of Conferences, 2017
The problem of finding the minimal eigenvalue corresponding to a positive eigenfunction of the nonlinear eigenvalue problem for the ordinary differential equation with coefficients depending on a spectral parameter is investigated. This problem arises in

Oscillatory property of solutions to nonlinear eigenvalue problems

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2019
This paper is concerned with the nonlinear eigenvalue problem \begin{equation*} -u''(t) = \lambda \left(u(t) + g(u(t))\right), \quad u(t) > 0, \quad t \in I := (-1,1), \quad u(\pm 1) = 0, \end{equation*} where $g(u) = u^p\sin(u^q)$ ($0 \le p < 1$,
