Asymptotic stability of solutions for a diffusive epidemic model

open access: yesDemonstratio Mathematica, 2022
The aim of this paper is to study the existence and the asymptotic stability of solutions for an epidemiologically emerging reaction-diffusion model. We show that the model has two types of equilibrium points to resolve the proposed system for a fairly ...

Properties of generalized degenerate parabolic systems

open access: yesAdvances in Nonlinear Analysis, 2022
In this article, we consider the parabolic system (ui)t=∇⋅(mUm−1A(∇ui,ui,x,t)+ℬ(ui,x,t)),(1≤i≤k){({u}^{i})}_{t}=\nabla \cdot (m{U}^{m-1}{\mathcal{A}}(\nabla {u}^{i},{u}^{i},x,t)+{\mathcal{ {\mathcal B} }}({u}^{i},x,t)),\hspace{1.0em}(1\le i\le k) in the ...

Asymptotic stability of an epidemiological fractional reaction-diffusion model

open access: yesDemonstratio Mathematica, 2023
The aim of this article is to study the known susceptible-infectious (SI) epidemic model using fractional order reaction-diffusion fractional partial differential equations [FPDEs] in order to better describe the dynamics of a reaction-diffusion SI with ...

Global Existence for some Cross Diffusion Systems with Equal Cross Diffusion/Reaction Rates

open access: yesAdvanced Nonlinear Studies, 2020
We consider some cross diffusion systems which is inspired by models in mathematical biology/ecology, in particular the Shigesada–Kawasaki–Teramoto (SKT) model in population biology.

The fractional Keller-Segel model [PDF]

open access: yes, 2006
The Keller-Segel model is a system of partial differential equations modelling chemotactic aggregation in cellular systems. This model has blowing up solutions for large enough initial conditions in dimensions d >= 2, but all the solutions are regular in

Random attractors for stochastic two-compartment Gray-Scott equations with a multiplicative noise

open access: yesOpen Mathematics, 2016
In this paper, we consider the existence of a pullback attractor for the random dynamical system generated by stochastic two-compartment Gray-Scott equation for a multiplicative noise with the homogeneous Neumann boundary condition on a bounded domain of

Long-time behavior of an angiogenesis model with flux at the tumor boundary [PDF]

open access: yes, 2012
This paper deals with a nonlinear system of partial differential equations modeling a simplified tumor-induced angiogenesis taking into account only the interplay between tumor angiogenic factors and endothelial cells.

Evolution Equations governed by Lipschitz Continuous Non-autonomous Forms [PDF]

open access: yes, 2014
We prove $L^2$-maximal regularity of linear non-autonomous evolutionary Cauchy problem \begin{equation}\label{eq00}\nonumber \dot{u} (t)+A(t)u(t)=f(t) \hbox{ for }\ \hbox{a.e.

Backward blow-up estimates and initial trace for a parabolic system of reaction-diffusion [PDF]

open access: yes, 2010
In this article we study the positive solutions of the parabolic semilinear system of competitive type \[ \left\{\begin{array} [c]{c}% u_{t}-\Delta u+v^{p}=0, v_{t}-\Delta v+u^{q}=0, \end{array} \right.

A cross-diffusion system derived from a Fokker-Planck equation with partial averaging [PDF]

open access: yes, 2016
A cross-diffusion system for two compoments with a Laplacian structure is analyzed on the multi-dimensional torus. This system, which was recently suggested by P.-L.
