Title: Analyse asymptotique d’un modèle de reproduction sexuée
Abstract: <p>We study the asymptotic behavior of stationary solutions to a quantitative genetics model with trait-dependent mortality and a nonlinear integral reproduction operator with a parameter describing the deviation between the offspring and the mean parental trait : the infinitesimal model. It accounts for the mixing of parental phenotypes at birth.<br /> <br /> Our asymptotic analysis encompasses the case when the parameter is typically small. Our approach is based on perturbative analysis techniques that require to describe accurately &nbsp;the correction to the Gaussian leading order profile. Our result extends previous results obtained with linear reproduction operator corresponding to asexual reproduction, but using an alternative methodology.</p>
