We introduce a stochastic individual model for the spatial behavior of an animal population of dispersive and competitive species, considering various kinds of biological effects, such as heterogeneity of environmental conditions, mutual attractive or repulsive interactions between individuals or competition between them for resources. As a consequence of the study of the large population limit, global existence of a nonnegative weak solution to a multidimensional parabolic strongly coupled… 
Well posedness and stochastic derivation of a diffusion-growth-fragmentation equation in a chemostat
We study the existence and uniqueness of the solution of a non-linear coupled system constituted of a degenerate diffusion-growth-fragmentation equation and a differential equation, resulting from
Quantitative mean-field limit for interacting branching diffusions
We establish an explicit rate of convergence for some systems of meaneld interacting di usions with logistic binary branching towards the solutions of nonlinear evolution equations with non-local
Stability of a cross-diffusion system and approximation by repulsive random walks: a duality approach
We consider conservative cross-di usion systems for two species where individual motion rates depend linearly on the local density of the other species. We develop duality estimates and obtain
A Non-local Cross-Diffusion Model of Population Dynamics I: Emergent Spatial and Spatiotemporal Patterns.
A spatially non-local cross-diffusion model of aggregation between multiple species with directed motion toward resource gradients is extended to include many species and more general kinds of dispersal and finds that for small spatial variations, there will be a combination of Turing patterns and patterning due to spatial forcing from the resources, whereas for large resource variations, spatial or spatiotemporal patterning can be modified greatly from what is predicted on homogeneous domains.
Rigorous Derivation of Population Cross-Diffusion Systems from Moderately Interacting Particle Systems
The global existence of strong solutions to the intermediate and the local diffusion systems is proved for sufficiently small initial data and numerical simulations on the particle level are presented.
Analysis and mean-field derivation of a porous-medium equation with fractional diffusion
A mean-field-type limit from stochastic moderately interacting many-particle systems with singular Riesz potential is performed, leading to nonlocal porous-medium equations in the whole space. The
Quantitative large-population asymptotics for mean- eld interacting branching di usions via optimal transport
We establish an explicit rate of convergence for some systems of meaneld interacting di usions with logistic binary branching, towards the solutions of non-linear evolution equations with non-local
Dynamique de concentration dans des équations aux dérivées partielles non locales issues de la biologie
This thesis focuses on the dynamics of Dirac mass concentrations in non-local partial differential and integro-differential equations motivated by evolutionary biology. We consider population models
Stochastic Models for Nonlinear Cross-Diffusion Systems
Under a priori assumptions concerning existence and uniqueness of the Cauchy problem solution for a system of quasilinear parabolic equations with cross-diffusion, we treat the PDE system as an


Analysis of a Multidimensional Parabolic Population Model with Strong Cross-Diffusion
The global existence of a nonnegative weak solution to a multidimensional parabolic strongly coupled model for two competing species is proved. The main feature of the model is that the diffusion
Invasion and adaptive evolution for individual-based spatially structured populations
This work considers a stochastic discrete model with birth, death, competition, mutation and spatial diffusion, where all the parameters may depend both on the position and on the phenotypic trait of individuals, and shows the important role of parameter scalings on clustering and invasion.
The non-local Fisher-KPP equation: travelling waves and steady states
We consider the Fisher–KPP equation with a non-local saturation effect defined through an interaction kernel (x) and investigate the possible differences with the standard Fisher–KPP equation. Our
Pattern and Waves for a Model in Population Dynamics with Nonlocal Consumption of Resources
We study a reaction-diffusion equation with an integral term describing nonlocal consumption of resources in population dynamics. We show that a homogeneous equilibrium can lose its stability
On the Entropic Structure of Reaction-Cross Diffusion Systems
This paper is devoted to the study of systems of reaction-cross diffusion equations arising in population dynamics. New results of existence of weak solutions are presented, allowing to treat systems
Global Well-Posedness of a Conservative Relaxed Cross Diffusion System
This work proves global existence in time of solutions to relaxed conservative cross diffusion systems governed by nonlinear operators of the form $u_i\to \partial_tu_i-\Delta(a_i(\tilde{u})u_ i)$, and proves existence of global weak solutions is obtained in any space dimension.
A microscopic probabilistic description of a locally regulated population and macroscopic approximations
This work generalizes a discrete model describing a locally regulated spatial population with mortality selection by adding spatial dependence and gives a path-wise description in terms of Poisson point measures.
