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

A one dimensional Hammerstein problem
Electronic Journal of Differential Equations, 1999 Nonlinear equations of the form $L[u]=lambda g(u)$ where $L$ is a linear operator on a function space and $g$ maps $u$ to the composition function $gcirc u$ arise in the theory of spontaneous combustion.

A Nonlinear eigenvalue problem with indefinite weights related to the Sobolev trace embedding [PDF]
, 2002 In this paper we study the Sobolev trace embedding W1,p([omega]) -->LpV ([delta omega]), where V is an indefinite weight. This embedding leads to a nonlinear eigenvalue problem where the eigenvalue appears at the (nonlinear) boundary condition.

On the Solution of the Eigenvalue Assignment Problem for Discrete-Time Systems
Journal of Applied Mathematics, 2017 The output feedback eigenvalue assignment problem for discrete-time systems is considered. The problem is formulated first as an unconstrained minimization problem, where a three-term nonlinear conjugate gradient method is proposed to find a local ...

A saturation phenomenon for a nonlinear nonlocal eigenvalue problem
, 2016 Given $1\le q \le 2$ and $\alpha\in\mathbb R$, we study the properties of the solutions of the minimum problem \[ \lambda(\alpha,q)=\min\left\{\dfrac{\displaystyle\int_{-1}^{1}|u'|^{2}dx+\alpha\left|\int_{-1}^{1}|u|^{q-1}u\, dx\right|^{\frac2q ...

Restarting projection methods for rational eigenproblems arising in fluid‐solid vibrations
Mathematical Modelling and Analysis, 2008 For nonlinear eigenvalue problems T(λ)x = 0 satisfying a minmax characterization of its eigenvalues iterative projection methods combined with safeguarded iteration are suitable for computing all eigenvalues in a given interval.

FEAST eigensolver for nonlinear eigenvalue problems [PDF]
Journal 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 ...
