报告摘要：In this paper, long time quantitative propagation of chaos in L1 -Wasserstein disstance for mean field interacting particle system is derived, where the diffusion coefficient is allowed to be interacting and the drift is assumed to be partially dissipative. The main tool relies on reflection coupling, the gradient estimate of the decoupled SDEs, and the Duhamel formula for two semigroups associated to two time-inhomogeneous diffusion processes on (R^d)*N . Moreover, the long time quantitative propagation of chaos in L^η (η ∈ (0, 1))-Wasserstein distance is also obtained.
