On the second eigenvalue of nonlinear eigenvalue problems

open access: yesElectronic Journal of Differential Equations, 2018
This article is devoted to the characterization of the second eigenvalue of nonlinear eigenvalue problems. We propose an abstract approach which allows to treat nonsmooth quasilinear problems and also to recover, in a unified way, previous results ...

Nonlinear Eigenvalue Problems with Specified Eigenvalues [PDF]

open access: yesSIAM Journal on Matrix Analysis and Applications, 2014
This work considers eigenvalue problems that are nonlinear in the eigenvalue parameter. Given such a nonlinear eigenvalue problem T, we are concerned with finding the minimal backward error such that T has a set of prescribed eigenvalues with prescribed algebraic multiplicities.

FEAST eigensolver for nonlinear eigenvalue problems [PDF]

open access: yesJournal 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 ...

Nonlinear nonhomogeneous Neumann eigenvalue problems

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2015
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.

The nonlinear eigenvalue problem [PDF]

open access: yesActa Numerica, 2017
Nonlinear eigenvalue problems arise in a variety of science and engineering applications, and in the past ten years there have been numerous breakthroughs in the development of numerical methods. This article surveys nonlinear eigenvalue problems associated with matrix-valued functions which depend nonlinearly on a single scalar parameter, with a ...

Nonlinearizing Two-parameter Eigenvalue Problems

open access: yesSIAM Journal on Matrix Analysis and Applications, 2021
We investigate a technique to transform a linear two-parameter eigenvalue problem, into a nonlinear eigenvalue problem (NEP). The transformation stems from an elimination of one of the equations in the two-parameter eigenvalue problem, by considering it as a (standard) generalized eigenvalue problem. We characterize the equivalence between the original

On minmax characterization in non-linear eigenvalue problems

open access: yesBruno Pini Mathematical Analysis Seminar, 2022
This is a note based on the paper [20] written in collaboration with N. Fusco and Y. Zhang. The main goal is to introduce minimax type variational characterization of non-linear eigenvalues of the p-Laplacian and other results related to shape and ...

Nonlinear Eigenvalue Problems for the Dirichlet (p,2)-Laplacian

open access: yesAxioms, 2022
We consider a nonlinear eigenvalue problem driven by the Dirichlet (p,2)-Laplacian. The parametric reaction is a Carathéodory function which exhibits (p−1)-sublinear growth as x→+∞ and as x→0+.

A linear eigenvalue algorithm for the nonlinear eigenvalue problem [PDF]

open access: yesNumerische Mathematik, 2012
A nonlinear matrix eigenvalue problem (NMEP) \(T(\lambda)x=0\) is transformed without loss of generality into a standard form \(\lambda B(\lambda)x=x\) (\(T\) and \(B\) analytic in \(\Omega\subset\mathbb{C}\)). This is then transformed into a linear operator eigenvalue problem (LOEP) of the form \(\lambda\mathcal{B}\varphi=\varphi\) (\(\varphi\in C_ ...
