Uniform long-time and propagation of chaos estimates for mean field kinetic particles in non-convex landscapes (2003.00735v2)
Published 2 Mar 2020 in math.PR and math.AP
Abstract: Combining the results of [14] and [10], the trend to equilibrium in large time is studied for a large particle system associated to a Vlasov-Fokker-Planck equation. Under some conditions (that allow non-convex confining potentials) the convergence rate is proven to be independent from the number of particles. From this are derived uniform in time propagation of chaos estimates and an exponentially fast convergence for the nonlinear equation itself.
