Asymptotic analysis of a selection model with space
Sepideh Mirrahimi, Benoit Perthame
Selection of a phenotypical trait can be described in mathematical terms by 'stage structured' equations which are usually written under the form of integral equations so as to exp…

Singular limits for reaction-diffusion equations with fractional Laplacian and local or nonlocal nonlinearity
Sylvie Méléard, Sepideh Mirrahimi
We perform an asymptotic analysis of models of population dynamics with a fractional Laplacian and local or nonlocal reaction terms. The first part of the paper is devoted to the l…

Influence of a spatial structure on the long time behavior of a competitive Lotka-Volterra type system
Hélène Leman, Sylvie Meleard, Sepideh Mirrahimi
To describe population dynamics, it is crucial to take into account jointly evolution mechanisms and spatial motion. However, the models which include these both aspects, are not s…
