Finite element method for a nonlinear problem

open access: yesComputer 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.

A nonlocal eigenvalue problem and the stability of spikes for reaction-diffusion systems with fractional reaction rates

open access: yes, 2003
We consider a nonlocal eigenvalue problem which arises in the study of stability of spike solutions for reaction-diffusion systems with fractional reaction rates such as the Sel'kov model, the Gray-Scott system, the hypercycle Eigen and Schuster ...

On the existence of equilibrium states of an elastic beam on a nonlinear foundation

open access: yesInternational 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.

An upper-lower solution method for the eigenvalue problem of Hadamard-type singular fractional differential equation

open access: yes, 2022
In this paper, we are concerned with the eigenvalue problem of Hadamard-type singular fractional differential equations with multi-point boundary conditions. By constructing the upper and lower solutions of the eigenvalue problem and using the properties

On a Nonlinear Elliptic Eigenvalue Problem

open access: yesJournal of Differential Equations, 1995
The eigenvalue problem \(- \Delta u- \mu u= \lambda g(x, u)\) in \(D\), \(u= 0\) on \(\partial D\), with prescribed energy condition is considered. Multiplicity results are proved, based on Lyusternik-Schnirelman theory.

Some indefinite nonlinear eigenvalue problems [PDF]

open access: yes, 2004
In this work we study the structure of the set of positive solutions of a nonlinear eigenvalue problem with a weight changing sign. Specifically, the reaction term arises from a population dynamic model. We use mainly bifurcation methods to obtain our

Triple‐Mode Ferroelectric Thin‐Film Transistor for Hybrid Electrical–Optical Reservoir Computing

open access: yesAdvanced Science, EarlyView.
A triple‐mode ferroelectric thin‐film transistor is developed by integrating Si3N4/HZO/IGZO layers to realize three independent memory modes: electric long‐term, electric short‐term, and optical short‐term. This single‐device architecture functions as both a reservoir and readout layer, achieving 92.43% MNIST accuracy. It offers a fully hardware‐based,

On a nonhomogeneous, nonlinear Dirichlet eigenvalue problem

open access: yesMathematische Nachrichten, 2023
AbstractWe consider a nonlinear eigenvalue problem for the Dirichlet ‐Laplacian with a sign‐changing Carathodory reaction. Using variational tools, truncation and comparison techniques, and critical groups, we prove an existence and multiplicity result which is global in the parameter (bifurcation‐type theorem).
