We are interested in this PhD in the study of solutions to the Boltzmann equation (elastic or inelastic) and the Landau equation. The axis of this study are the regularity and asymptotic behavior of the solutions, and we systematically search for quantitative results. In the first part, we consider on the one hand the spatially homogeneous solutions to the Boltzmann equation, for which we prove propagation of regularity and damping of singularities for short-range interactions, as well as propagation of integrability bounds for long-range interactions. On the other hand, we quantify the positivity of the spatially inhomogeneous solutions, under regularity assumptions. In the second part, we give spectral gap and coercivity estimates for the...
