Propagation or extinction in bistable equations: the non-monotone role of initial fragmentation

Matthieu Alfaro, François Hamel, Lionel Roques

In this paper, we investigate the large-time behavior of bounded solutions of the Cauchy problem for a reaction-diffusion equation in with bistable reaction term. We…

The field-road diffusion model: fundamental solution and asymptotic behavior

Matthieu Alfaro, Romain Ducasse, Samuel Tréton

We consider the linear field-road system, a model for fast diffusion channels in population dynamics and ecology. This system takes the form of a system of PDEs set on domains of d…

Quantifying the threshold phenomena for propagation in nonlocal diffusion equations

Matthieu Alfaro, Arnaud Ducrot, Hao Kang

We are interested in the threshold phenomena for propagation in nonlocal diffusion equations with some compactly supported initial data. In the so-called bistable and ignition case…

Confining integro-differential equations originating from evolutionary biology: ground states and long time dynamics

Matthieu Alfaro, Pierre Gabriel, Otared Kavian

We consider nonlinear mutation selection models, known as replicator-mutator equations in evolutionary biology. They involve a nonlocal mutation kernel and a confining fitness pote…

Lotka-Volterra competition-diffusion system: the critical competition case

Matthieu Alfaro, Dongyuan Xiao

We consider the reaction-diffusion competition system in the so-called {\it critical competition case}. The associated ODE system then admits infinitely many equilibria, which make…

On the modelling of spatially heterogeneous nonlocal diffusion: deciding factors and preferential position of individuals

Matthieu Alfaro, Thomas Giletti, Yong-Jung Kim +2

We develop general heterogeneous nonlocal diffusion models and investigate their connection to local diffusion models by taking a singular limit of focusing kernels. We reveal the…
