Numerical solution of a malignant invasion model using some finite difference methods

open access: yesDemonstratio Mathematica, 2023
In this article, one standard and four nonstandard finite difference methods are used to solve a cross-diffusion malignant invasion model. The model consists of a system of nonlinear coupled partial differential equations (PDEs) subject to specified ...

Existence of steady-state solutions for a class of competing systems with cross-diffusion and self-diffusion

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2021
We focus on a system of two competing species with cross-diffusion and self-diffusion. By constructing an appropriate auxiliary function, we derive the sufficient conditions such that there are no coexisting steady-state solutions to the model.

Stationary patterns of a ratio-dependent predator-prey system with cross-diffusion

open access: yesMathematical Modelling and Analysis, 2011
This paper is concerned with a ratio-dependent predator-prey system with diffusion and cross-diffusion in a bounded domain with no flux boundary condition. We establish the existence and non-existence of non-constant positive steady states (patterns). In

Lie symmetries of the Shigesada-Kawasaki-Teramoto system [PDF]

open access: yes, 2016
The Shigesada-Kawasaki-Teramoto system, which consists of two reaction-diffusion equations with variable cross-diffusion and quadratic nonlinearities, is considered.

Rigorous mean-field limit and cross-diffusion [PDF]

open access: yesZeitschrift für angewandte Mathematik und Physik, 2019
The mean-field limit in a weakly interacting stochastic many-particle system for multiple population species in the whole space is proved. The limiting system consists of cross-diffusion equations, modeling the segregation of populations. The mean-field limit is performed in two steps: First, the many-particle system leads in the large population limit

Dynamics of a Leslie-Gower predator-prey system with cross-diffusion

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2020
A Leslie–Gower predator–prey system with cross-diffusion subject to Neumann boundary conditions is considered. The global existence and boundedness of solutions are shown.

Coaxial Cross-Diffusion through Carbon Nantoubes

open access: yesThe Journal of Physical Chemistry B, 2009
We present results from nonequilibrium molecular dynamics experiments describing the relaxation of local concentrations at two reservoirs, initially filled with water (W) and acetonitrile (ACN), as they become connected through a membrane composed of (16,16) carbon nanotubes.

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.

Mathematical analysis of toxin-phytoplankton-fish model with self-diffusion and cross-diffusion

open access: yesBiomath, 2019
In this paper  we propose a nonlinear reaction-diffusion system  describing the interaction between toxin-producing phytoplankton and fish population. We analyze the effect of self- and cross-diffusion on the dynamics of the system.
