On a New Characterization of Some Class Nonlinear Eigenvalue Problem

open access: yesAdvances in Mathematical Physics, 2019
A normal mode analysis of a vibrating mechanical or electrical system gives rise to an eigenvalue problem. Faber made a fairly complete study of the existence and asymptotic behavior of eigenvalues and eigenfunctions, Green’s function, and expansion ...

Eigenvalue problem for nonlinear elastic beam equation of fractional order

open access: yesNonlinear Analysis, 2017
In this study, under some suitable assumptions, we determine an explicit eigenvalue interval for the existence of positive solution of singular fractional-order nonlinear elastic beam equation with bending term.

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.

Approximation of the Minimal Eigenvalue for a Nonlinear Sturm–Liouville Problem [PDF]

open access: yesУчёные записки Казанского университета: Серия Физико-математические науки, 2015
Properties of the minimal eigenvalue corresponding to the positive eigenfunction of a nonlinear eigenvalue problem for an ordinary differential equation are studied. This problem is approximated by a mesh scheme of the finite element method. The error of

COMPACTNESS OF A NONLINEAR EIGENVALUE PROBLEM WITH A SINGULAR NONLINEARITY [PDF]

open access: yesCommunications in Contemporary Mathematics, 2008
We study the Dirichlet boundary value problem [Formula: see text] on a bounded domain Ω ⊂ ℝN. For 2 ≤ N ≤ 7, we characterize compactness for solutions sequence in terms of spectral informations. As a by-product, we give an uniqueness result for λ close to 0 and λ* in the class of all solutions with finite Morse index, λ* being the extremal value ...

Comment on ‘Nonlinear eigenvalue problems’ [PDF]

open access: yesJournal of Physics A: Mathematical and Theoretical, 2014
The asymptotic behaviour of solutions to y'(x)=cos[πxy(x)] was investigated by Bender et al (2014 J. Phys. A: Math. Theor. 47 235204). They found, for example, a relation between the initial value y(0)=a and the number of maxima that the solution exhibited.

Positive solutions of nonlinear fourth-order boundary-value problems with local and non-local boundary conditions [PDF]

open access: yes, 2008
We establish new existence results for multiple positive solutions of fourth-order nonlinear equations which model deflections of an elastic beam. We consider the widely studied boundary conditions corresponding to clamped and hinged ends and many non ...
