Abstract
In this paper, we study nonlinear functionals measuring potential interactions and L 1-distance between two mild solutions for the multi-dimensional discrete velocity Boltzmann equations when the initial data are a small perturbation of a vacuum. We employ Bony's dispersion estimates to show that these functionals satisfy Lyapunov type estimates which are useful for the study of time-asymptotics and L 1-stability of mild solutions.
