Received  April 2014 Revised  September 2015 Published  October 2015

We prove a quantitative propagation of chaos and entropic chaos, uniformly in time, for the spatially homogeneous Landau equation in the case of Maxwellian molecules. We improve the results of Fontbona, Guérin and Méléard [9] and Fournier [10] where the propagation of chaos is proved for finite time. Moreover, we prove a quantitative estimate on the rate of convergence to equilibrium uniformly in the number of particles.
Keywords: Landau equation, trend to equilibrium., entropic chaos, Maxwellian molecules, grazing collisions, Chaos, propagation of chaos.
