Analysis of a model describing bacterial colony expansion in radial geometry driven by chemotaxis

open access: yesEuropean Journal of Applied Mathematics
We investigate a recent model proposed in the literature elucidating patterns driven by chemotaxis, similar to viscous fingering phenomena. Notably, this model incorporates a singular advection term arising from a modified formulation of Darcy’s law.

Stabilization in a chemotaxis system modelling T-cell dynamics with simultaneous production and consumption of signals

open access: yesEuropean Journal of Applied Mathematics
In a smoothly bounded domain $\Omega \subset \mathbb{R}^n$ , $n\ge 1$ , this manuscript considers the homogeneous Neumann boundary problem for the chemotaxis system \begin{eqnarray*} \left \{ \begin{array}{l} u_t = \Delta u - \nabla \cdot (

Global boundedness in a two-dimensional chemotaxis system with nonlinear diffusion and singular sensitivity

open access: yesAdvances in Nonlinear Analysis
In this study, we investigate the two-dimensional chemotaxis system with nonlinear diffusion and singular sensitivity: ut=∇⋅(uθ−1∇u)−χ∇⋅uv∇v,x∈Ω,t>0,vt=Δv−v+u+g(x,t),x∈Ω,t>0,(∗)\left\{\begin{array}{ll}{u}_{t}=\nabla \cdot \left({u}^{\theta -1}\nabla u ...

Travelling waves with continuous profile for hyperbolic Keller-Segel equation

open access: yesEuropean Journal of Applied Mathematics
This work describes a hyperbolic model for cell-cell repulsion with population dynamics. We consider the pressure produced by a population of cells to describe their motion.

Global dynamics for the generalised chemotaxis-Navier–Stokes system in $\mathbb{R}^3$

open access: yesEuropean Journal of Applied Mathematics
We consider the chemotaxis-Navier–Stokes system with generalised fluid dissipation in $\mathbb{R}^3$ : \begin{eqnarray*} \begin{cases} \partial _t n+u\cdot \nabla n=\Delta n- \nabla \cdot (\chi (c)n \nabla c),\\[5pt] \partial _t c+u \cdot \nabla

Keller–Segel type approximation for nonlocal Fokker–Planck equations in one-dimensional bounded domain

open access: yesEuropean Journal of Applied Mathematics
Numerous evolution equations with nonlocal convolution-type interactions have been proposed. In some cases, a convolution was imposed as the velocity in the advection term.

Derivation and travelling wave analysis of phenotype-structured haptotaxis models of cancer invasion

open access: yesEuropean Journal of Applied Mathematics
We formulate haptotaxis models of cancer invasion wherein the infiltrating cancer cells can occupy a spectrum of states in phenotype space, ranging from ‘fully mesenchymal’ to ‘fully epithelial’. The more mesenchymal cells are those that display stronger

Cahn–Hilliard equations with singular potential, reaction term and pure phase initial datum

open access: yesEuropean Journal of Applied Mathematics
We consider local and nonlocal Cahn–Hilliard equations with constant mobility and singular potentials including, e.g., the Flory–Huggins potential, subject to no-flux (or periodic) boundary conditions.
