Quantitative propagation of chaos for non-exchangeable diffusions via first-passage percolation
Daniel Lacker, Lane Chun Yeung, Fuzhong Zhou
This paper develops a non-asymptotic approach to mean field approximations for systems of diffusive particles interacting pairwise. The interaction strengths are not identical,…

Sharp propagation of chaos for mean field Langevin dynamics, control, and games
Manuel Arnese, Daniel Lacker
We establish the sharp rate of propagation of chaos for McKean-Vlasov equations with coefficients that are non-linear in the measure argument, i.e., not necessarily given by pairwi…
