Reaction Diffusion Equations with Nonlocal Boundary and Nonlocal Initial Conditions

Journal of Mathematical Analysis and Applications, 1995
The author considers the existence, multiplicity, and asymptotic behavior of solutions for a reaction diffusion equation under nonlocal boundary and nonlocal initial conditions. The main results are the theorems about the existence of multiple solutions for both the time-dependent and the steady-state problems, and that each of the time-dependent ...

Metal nanostructure‐coupled label‐free localized surface plasmon resonance biosensors for rapid and sensitive disease diagnosis

BMEMat, EarlyView.
LSPR biosensing enables rapid, sensitive, and low‐sample‐volume detection of biomarkers, with broad applications in diagnosing cancer, infectious, and chronic diseases. Advances in nanostructure design, micro/nanofabrication, and microfluidic integration have expanded the potential of LSPR sensors in biomedical diagnostics.

Fractional-order nonlocal wave propagation in hygro-piezo-photo-thermoelastic semiconductors with dual-moisture diffusion and laser excitation

Journal of Low Frequency Noise, Vibration and Active Control
This study investigates the propagation of coupled waves in a nonlocal hygro-piezo-photo-thermoelastic semiconductor medium subjected to dual-moisture diffusion and fractional-order heat conduction. The mathematical model incorporates the effects of long-

On some nonlocal, nonlinear diffusion problems

Mathematical Models and Methods in Applied Sciences
This paper is devoted to some nonlocal, nonlinear elliptic problems with an emphasis on the computation of the solution of such problems, reducing it in particular to a fixed point argument in [Formula: see text]. Error estimates and numerical experiments are provided.

Nonlocal degenerate reaction-diffusion equations with general nonlinear diffusion term

Electronic Journal of Differential Equations, 2014
We study a class of second-order nonlocal degenerate semilinear reaction-diffusion equations with general nonlinear diffusion term. Under a set of conditions on the general nonlinear diffusivity and nonlinear nonlocal source term, we prove global ...

Nonlocal Approximation of Slow and Fast Diffusion

Journal of Differential Equations
Motivated by recent work on approximation of diffusion equations by deterministic interacting particle systems, we develop a nonlocal approximation for a range of linear and nonlinear diffusion equations and prove convergence of the method in the slow, linear, and fast diffusion regimes.
