A Domain Decomposition Method for Time Fractional Reaction-Diffusion Equation [PDF]

open access: yesThe Scientific World Journal, 2014
The computational complexity of one-dimensional time fractional reaction-diffusion equation is O(N2M) compared with O(NM) for classical integer reaction-diffusion equation. Parallel computing is used to overcome this challenge.

Time Fractional Fisher–KPP and Fitzhugh–Nagumo Equations

open access: yesEntropy, 2020
A standard reaction–diffusion equation consists of two additive terms, a diffusion term and a reaction rate term. The latter term is obtained directly from a reaction rate equation which is itself derived from known reaction kinetics, together with ...

A survey of numerical schemes for transportation equation [PDF]

open access: yesE3S Web of Conferences, 2021
The convection-diffusion equation is a fundamental equation that exists widely. The convection-diffusion equation consists of two processes: diffusion and convection. The convection-diffusion equation can also be called drift-diffusion equaintion.

Spatial dynamics of a nonlocal bistable reaction diffusion equation

open access: yesElectronic Journal of Differential Equations, 2020
This article concerns a nonlocal bistable reaction-diffusion equation with an integral term. By using Leray-Schauder degree theory, the shift functions and Harnack inequality, we prove the existence of a traveling wave solution connecting 0 to an ...

Green’s Functions on Various Time Scales for the Time-Fractional Reaction-Diffusion Equation

open access: yesAdvances in Mathematical Physics, 2023
The time-fractional diffusion equation coupled with a first-order irreversible reaction is investigated by employing integral transforms. We derive Green’s functions for short and long times via approximations of the Mittag-Leffler function.

Qualitative properties of solutions to a reaction-diffusion equation with weighted strong reaction

open access: yesElectronic Journal of Differential Equations, 2023
We study the existence and qualitative properties of solutions to the Cauchy problem associated to the quasilinear reaction-diffusion equation $$ \partial_tu=\Delta u^m+(1+|x|)^{\sigma}u^p, $$ posed for \((x,t)\in\mathbb{R}^N\times(0,\infty)\), where ...

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

Exact Solutions for Some Partial Differential Equations by Using First Integral Method [PDF]

open access: yesالمجلة العراقية للعلوم الاحصائية, 2011
In this paper, some exact solutions for the convection–diffusion–reaction equation in two dimensions and a nonlinear system of partial differential equations are formally derived by using the first integral method, which are based on the theory of ...
