Nonlinear eigenvalue problems for higher order Lidstone boundary value problems
Electronic 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.

Perturbations of nonlinear eigenvalue problems
, 2018 We consider perturbations of nonlinear eigenvalue problems driven by a nonhomogeneous differential operator plus an indefinite potential. We consider both sublinear and superlinear perturbations and we determine how the set of positive solutions changes ...

A study on anisotropic mesh adaptation for finite element approximation of eigenvalue problems with anisotropic diffusion operators [PDF]
, 2014 Anisotropic mesh adaptation is studied for the linear finite element solution of eigenvalue problems with anisotropic diffusion operators. The M-uniform mesh approach is employed with which any nonuniform mesh is characterized mathematically as a uniform

Oscillatory property of solutions to nonlinear eigenvalue problems
Electronic 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 $g(u) = u^p\sin(u^q)$ ($0 \le p < 1$,

Regularized Normalization Methods for Solving Linear and Nonlinear Eigenvalue Problems
Mathematics, 2023 To solve linear and nonlinear eigenvalue problems, we develop a simple method by directly solving a nonhomogeneous system obtained by supplementing a normalization condition on the eigen-equation for the uniqueness of the eigenvector.

Time Dependent Resonance Theory [PDF]
, 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.
