Studying wildfire fronts using advection-diffusion-reaction models

K Mitra, Q Peng, C Reisch - arXiv preprint arXiv:2401.17468, 2024 - arxiv.org
In this work, we study the propagation of wildfires using an advection--diffusion--reaction
model which also includes convective and radiative heat loss. An existing model is …

Well-posedness and qualitative properties of quasilinear degenerate evolution systems

K Mitra, S Sonner - arXiv preprint arXiv:2304.00175, 2023 - arxiv.org
We analyze nonlinear degenerate coupled PDE-PDE and PDE-ODE systems that arise, for
example, in the modelling of biofilm growth. One of the equations, describing the evolution of …

A mathematical model of discrete attachment to a cellulolytic biofilm using random DEs

J Hughes - 2021 - atrium.lib.uoguelph.ca
We propose a new mathematical framework for the addition of stochastic attachment to
biofilm models via the use of random ordinary differential equations. We focus our approach …

Stability analysis of hyperbolic-parabolic free boundary problems modelling biofilms

DZ Balike, MR Mattei, L Frunzo - arXiv preprint arXiv:2411.16977, 2024 - arxiv.org
We present the stability analysis of two free boundary problems arising in biofilm modelling.
The first, introduced in the 1980s by Wanner and Gujer, is related to the competition …

Long time behavior of a parabolic p-Laplacian equation coupled to a compartmental ODE system with an induction threshold phenomenon

MA Efendiev, M Ôtani, HJ Eberl - Journal of Differential Equations, 2022 - Elsevier
We study the existence and the longterm behavior of solutions of a parabolic equation
governed by the p-Laplacian with nonlinear growth terms that are coupled with the solutions …

Coupled reaction-diffusion equations with degenerate diffusivity: wavefront analysis

E Muñoz-Hernández, E Sovrano, V Taddei - arXiv preprint arXiv …, 2023 - arxiv.org
We investigate traveling wave solutions for a nonlinear system of two coupled reaction-
diffusion equations characterized by double degenerate diffusivity:\[n_t=-f (n, b),\quad b_t=[g …

Cauchy problem for singular-degenerate porous medium type equations: well-posedness and Sobolev regularity
