Stochastic reaction–diffusion equations on networks [PDF]

open access: yesJournal of Evolution Equations, 2021
AbstractWe consider stochastic reaction–diffusion equations on a finite network represented by a finite graph. On each edge in the graph, a multiplicative cylindrical Gaussian noise-driven reaction–diffusion equation is given supplemented by a dynamic Kirchhoff-type law perturbed by multiplicative scalar Gaussian noise in the vertices.

Nonlocal Reaction-Diffusion Equations in Population Dynamics [PDF]

open access: yesMemoirs of the Scientific Sections of the Romanian Academy, 2019
This paper is dedicated to the memory of Narcisa Apreutesei Various problems in population dynamics are described by nonlocal reactiondiffusion equations, where the conventional logistic term for the reproduction rate is replaced by some integral ...

Reaction–diffusion equations for the infinity Laplacian [PDF]

open access: yesNonlinear Analysis, 2020
We derive sharp regularity for viscosity solutions of an inhomogeneous infinity Laplace equation across the free boundary, when the right hand side does not change sign and satisfies a certain growth condition. We prove geometric regularity estimates for solutions and conclude that once the source term is comparable to a homogeneous function, then the ...

Asymptotic Behavior of Stochastic Reaction–Diffusion Equations

open access: yesMathematics
In this paper, we concentrate on the propagation dynamics of stochastic reaction–diffusion equations, including the existence of travelling wave solution and asymptotic wave speed. Based on the stochastic Feynman–Kac formula and comparison principle, the

Splitting spectral element method for fractional reaction-diffusion equations

open access: yesJournal of Algorithms & Computational Technology, 2020
In this paper, we propose a second-order operator splitting spectral element method for solving fractional reaction-diffusion equations. In order to achieve a fast second-order scheme in time, we decompose the original equation into linear and nonlinear ...

Novel Evaluation of Fuzzy Fractional Cauchy Reaction-Diffusion Equation

open access: yesJournal of Function Spaces, 2022
The present research correlates with a fuzzy hybrid approach merged with a new iterative transform method known as the fuzzy new iterative transform method. With the help of Atangana-Baleanu under generalized Hukuhara differentiability, we show that this

Attractor of reaction-diffusion equations in Banach spaces

open access: yesApplied General Topology, 2001
In this paper we prove first some abstract theorems on existence of global attractors for differential inclusions generated by w-dissipative operators. Then these results are applied to reaction-diffusion equations in which the Babach space Lp is used as

Method of Monotone Solutions for Reaction-Diffusion Equations

open access: yesСовременная математика: Фундаментальные направления, 2017
Existence of solutions of reaction-diffusion systems of equations in unbounded domains is studied by the Leray-Schauder (LS) method based on the topological degree for elliptic operators in unbounded domains and on a priori estimates of solutions in ...
