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.

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

Local existence result of the single dopant diffusion including cluster reactions of high order

open access: yesAbstract and Applied Analysis, Volume 6, Issue 1, Page 13-34, 2001., 2001
We consider the pair diffusion process which includes cluster reactions of high order. We are able to prove a local (in time) existence result in arbitrary space dimensions. The model includes a nonlinear system of reaction‐drift‐diffusion equations, a nonlinear system of ordinary differential equations in Banach spaces, and a nonlinear elliptic ...

Random attractors for stochastic retarded reaction-diffusion equations with multiplicative white noise on unbounded domains

open access: yesOpen Mathematics, 2018
In this paper we investigate the stochastic retarded reaction-diffusion equations with multiplicative white noise on unbounded domain ℝn (n ≥ 2). We first transform the retarded reaction-diffusion equations into the deterministic reaction-diffusion ...

Well-posedness of Cauchy problem of fractional drift diffusion system in non-critical spaces with power-law nonlinearity

open access: yesAdvances in Nonlinear Analysis
In this article, we consider the global and local well-posedness of the mild solutions to the Cauchy problem of fractional drift diffusion system with higher-order nonlinearity. The main difficulty comes from the higher-order nonlinearity. Instead of the

Vibration of Dry Ice Placed on a Metallic Structure [PDF]

open access: yes, 2018
Vibration of a dry ice block placed on a metallic beam structure is analyzed under two steps, i.e. a sublimation step under high heat flux using one-dimensional linearized heat conduction equation neglecting gaseous flow and the following jump stage of ...

Local And Global Existence Of Solutions To Semilinear Parabolic Initial Value Problems

open access: yes, 2001
: This paper is devoted to establishing local and global existence theorems for autonomous semilinear parabolic initial value problems. The local existence theorems do not require Lipchitz condition on nonlinear term.

System of degenerate parabolic p-Laplacian

open access: yesOpen Mathematics
In this article, we study the mathematical properties of the solution u=(u1,…,uk){\bf{u}}=({u}^{1},\ldots ,{u}^{k}) to the degenerate parabolic system ut=∇⋅(∣∇u∣p−2∇u),(p>2).{{\bf{u}}}_{t}=\nabla \hspace{0.25em}\cdot \hspace{0.25em}({| \nabla {\bf{u}}| }^

A free boundary model for transport-induced neurite growth

open access: yesEuropean Journal of Applied Mathematics
We introduce a free boundary model to study the effect of vesicle transport onto neurite growth. It consists of systems of drift-diffusion equations describing the evolution of the density of antero- and retrograde vesicles in each neurite coupled to ...
