Eigenvalue Problem for Nonlinear Fractional Differential Equations with Integral Boundary Conditions
Abstract and Applied Analysis, 2014 By employing known Guo-Krasnoselskii fixed point theorem, we investigate the eigenvalue interval for the existence and nonexistence of at least one positive solution of nonlinear fractional differential equation with integral boundary conditions.

Finite element approximation of the first eigenvalue of a nonlinear problem for some special domain
Electronic Journal of Qualitative Theory of Differential Equations, 2000 In this paper we present a method for the numerical approximation of the smallest eigenvalue of a nonlinear eigenvalue problem using the finite element method.

The Effects of Monetary Policy in the United Kingdom: New Evidence From SONIA Market Responses
International Journal of Finance &Economics, EarlyView.ABSTRACT This paper constructs a new measure of the UK monetary policy instrument (MPI) using daily changes in the sterling overnight index average (SONIA) around Bank of England policy events from June 1997 to August 2025. The instrument explicitly accounts for pre‐event information and unconventional monetary policy (UMP) using lagged macro‐financial

Positive Solutions for Nonlinear Eigenvalue Problems
Journal of Mathematical Analysis and Applications, 1997 The authors are concerned with determining values of \(\lambda\) (eigenvalues), for which there exist positive solutions of the boundary value problem \[ (1_\lambda)\quad u''+\lambda a(t)f(u)=0 ...

Identifying Peer Effects in Networks with Unobserved Effort and Isolated Students
Journal of Applied Econometrics, EarlyView.ABSTRACT Peer influence on effort devoted to some activity is often studied when effort is unobserved, and the researcher instead observes an outcome that combines effort with other shocks. For instance, in education, achievement measures such as GPA reflect both effort and idiosyncratic GPA shocks.

Positive solutions of singular fourth-order three-point eigenvalue problem
四川大学学报. 自然科学版, 2017 In this paper we investigate the problem of existence of positive solutions for the nonlinear singular fourth-order three-point eigenvalue problem u^{(4)}(t)=\lambda a(t)f(t,u(t)),t\in [0,1], u(0)=u'(\eta)=u''(1)=u'''(0)=0, where \lambda is a positive ...

Existence of Solutions of a Discrete Fourth-Order Boundary Value Problem
Discrete Dynamics in Nature and Society, 2010 Let a,b be two integers with b-a≥5 and let 𝕋2={a+2,a+3,…,b-2}. We show the existence of solutions for nonlinear fourth-order discrete boundary value problem Δ4u(t-2)=f(t,u(t), Δ2u(t-1)), t∈𝕋2, u(a+1)=u(b-1)=Δ2u(a)=Δ2u(b-2)=0 under a ...

Journal of Intelligent Medicine, EarlyView.Abstract Simultaneous electroencephalography (EEG) recording during transcranial alternating current stimulation (tACS) is strongly contaminated by stimulation artifacts, limiting direct assessment of neural activity. Steady‐state visual evoked potentials (SSVEPs) provide frequency‐specific and phase‐locked responses, making them suitable for ...

Quantization of Polaritons Confined in Dielectric Structures
Laser &Photonics Reviews, EarlyView.This study addresses the limitations of the Hopfield model of strong light‐matter coupling in the case of structured dieletrics. A method to derive quantum models in the polariton basis using Bogoliubov transformation and third quantization is introduced, demonstrating how to boost interaction strength and engineer nonlocal interactions for strongly ...

Resonant States Reveal Strong Light–Matter Coupling in Nanophotonic Cavities
Laser &Photonics Reviews, EarlyView.Photonic resonant states reveal characteristics of coupled light–matter systems that would otherwise be hidden by damping. Their trajectories (when tuning the optical resonance) undergo a qualitative change at the onset of strong coupling: They start swapping positions.
