Singular limit of an Allen–Cahn equation with nonlinear diffusion

P El Kettani, T Funaki, D Hilhorst, H Park… - Tunisian Journal of …, 2023 - msp.org
Abstract We consider an Allen–Cahn equation with nonlinear diffusion, motivated by the
study of the scaling limit of certain interacting particle systems. We investigate its singular …

Mean curvature interface limit from Glauber+ Zero-range interacting particles

P El Kettani, T Funaki, D Hilhorst, H Park… - … in Mathematical Physics, 2022 - Springer
We derive a continuum mean-curvature flow as a certain hydrodynamic scaling limit of a
class of Glauber+ Zero-range particle systems. The Zero-range part moves particles while …

[HTML][HTML] Chemotactic traveling waves with compact support

SH Choi, YJ Kim - Journal of Mathematical Analysis and Applications, 2020 - Elsevier
A logarithmic model type chemotaxis equation is introduced with porous medium diffusion

Global classical solvability in a food metric chemotaxis system under zero boundary conditions at infinity

J Ahn, SH Choi, M Yoo - Nonlinear Analysis, 2022 - Elsevier
We consider the nutrient–chemotaxis model, derived by a food metric, on the real line. The
model consists of the equation for the nutrient density of ordinary differential equation type …

Singular limit of a stochastic Allen-Cahn equation with nonlinear diffusion

P El Kettani, D Hilhorst, H Park - Journal of Differential Equations, 2024 - Elsevier
We study a stochastic Allen-Cahn equation with nonlinear diffusion and a mild multiplicative
noise on a bounded domain in R n. We consider initial data which satisfy some non …

Global wellposedness of nutrient-taxis systems derived by a food metric

J Ahn, SH Choi, M Yoo - Discrete and Continuous Dynamical …, 2021 - aimsciences.org
This paper deals with the nutrient-taxis system derived by a food metric. The system was
proposed in [Sun-Ho Choi and Yong-Jung Kim: Chemotactic traveling waves by metric of …

Hyperbolic limit for a biological invasion

D Hilhorst, Y Kim, TN Nguyen… - Discrete and Continuous …, 2023 - aimsciences.org
In a spatially heterogeneous environment the propagation speed of a biological invasion
varies in space. The traveling wave theory in a homogeneous case is not extended to a …
