Title: Dynamics of McKean-Vlasov type with weak regularity conditions and related particle approximations
Abstract: This talk is dedicated to present quantitative propagation of chaos results for smoothened interacting particle systems related to a class of singular kinetic/Langevin-type McKean-Vlasov SDEs driven by a non-degenerate symmetric stable Levy noise. Singularities in the mean-field limit emerges with a pairwise interaction kernel belonging to a class of mixed Besov spaces with negative smoothness. Specificall, we establish different weak and trajectorial propagation of chaos results in the Brownian and pure-jump regimes.
(This talk is based on a joint work with Zimo Hao, St茅phane Menozzi, Michael R枚ckner and Xicheng Zhang.)
