Abstract:	For perturbation solutions to kinetic equations near Maxwellians, we introduce a weighted energy functional whose dissipation rate is quartic, that can be used for treating the large-velocity growth in the nonlinear estimates due to degeneration of the linearized collision operators for soft potentials. As an immediate application, I will talk about the stability of contact waves for the Landau equation in the Coulomb case. https://meeting.tencent.com/s/QACMVIJzip8U
