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

Finite element method for a nonlinear problem
Computer Assisted Methods in Engineering and Science, 2023 We consider the nonlinear eigenvalue problem of a nonlinear partial differential equation under Dirichlet boundary condition in a two-dimensional space. The classical solutions are given for rectangular domains.

Nonlinear nonhomogeneous Neumann eigenvalue problems
Electronic Journal of Qualitative Theory of Differential Equations, 2015 Summary: We consider a nonlinear parametric Neumann problem driven by a nonhomogeneous differential operator with a reaction which is \((p-1)\)-superlinear near \(\pm\infty\) and exhibits concave terms near zero. We show that for all small values of the parameter, the problem has at least five solutions, four of constant sign and the fifth nodal.

On the existence of equilibrium states of an elastic beam on a nonlinear foundation
International Journal of Mathematics and Mathematical Sciences, 1993 This paper concerns the existence and uniqueness of equilibrium states of a beam-column with hinged ends which is acted upon by axial compression and lateral forces and is in contact with a semi-infinite medium acting as a foundation.

Pattern selection as a nonlinear eigenvalue problem
, 1996 A unique pattern selection in the absolutely unstable regime of driven, nonlinear, open-flow systems is reviewed. It has recently been found in numerical simulations of propagating vortex structures occuring in Taylor-Couette and Rayleigh-Benard systems ...

On a New Characterization of Some Class Nonlinear Eigenvalue Problem
Advances 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 ...

On the approximation of the principal eigenvalue for a class of nonlinear elliptic operators
, 2016 We present a finite difference method to compute the principal eigenvalue and the corresponding eigenfunction for a large class of second order elliptic operators including notably linear operators in nondivergence form and fully nonlinear operators. The
