Traveling wave solutions for a neutral reaction–diffusion equation with non-monotone reaction
Advances in Difference Equations, 2019 In the present paper, we firstly improve the results on traveling wave solution that were established in (Liu and Weng in J. Differ. Equ. 258:3688–3741, 2015) for a neutral reaction–diffusion equation with quasi-monotone reaction.

Waveform relaxation for reaction–diffusion equations
Journal of Computational and Applied Mathematics, 2011 The authors propose a new waveform relaxation algorithm for general semi-linear reaction-diffusion equations. Compared with the classical waveform relaxation algorithm, the new one has two advantages: the first one is that the system is not decomposed into sub-systems; the second one is represented by the fact that the convergence rate of the new ...

Reaction–diffusion equations for the infinity Laplacian [PDF]
Nonlinear 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 ...

A conforming discontinuous finite element method for diffusion-reaction equations
四川大学学报. 自然科学版, 2023 For the primal-mixed form of the steady diffusion-reaction equation, a new conforming discontinuous finite element scheme is proposed by using the idea of discontinuous finite element method and the least-square method. Then the method is extended to the

On a semilinear fractional reaction-diffusion equation with nonlocal conditions
Alexandria Engineering Journal, 2021 In the present paper, a nonlocal problem for semilinear fractional diffusion equations with Riemann-Liouville derivative is investigated. By applying Banach fixed point theorem combined with some techniques on Mittag-Leffler functions, we establish some ...

Noise and stability in reaction-diffusion equations
Mathematical Control & Related Fields, 2022 <p style='text-indent:20px;'>We study the stability of reaction-diffusion equations in presence of noise. The relationship of stability of solutions between the stochastic ordinary different equations and the corresponding stochastic reaction-diffusion equation is firstly established.
