I will present an analytic method which extends the framework of standard perturbation theory to the study of non-cold species. The main motivation of this work is to get a theoretical prediction of the shape of the non-linear matter power spectrum when the effect of neutrinos is taken into account. Modeling properly this effect is important in particular if we want to get constraints on neutrino masses from large-scale structure surveys.
