This paper develops a nonasymptotic, local approach to quantitative propagation of chaos
for a wide class of mean field diffusive dynamics. For a system of n interacting particles, the …

Well-posedness of distribution dependent SDEs with singular drifts

M Röckner, X Zhang - 2021 - projecteuclid.org
Consider the following distribution dependent SDE: dXt= σt (Xt, μXt) dWt+ bt (Xt, μXt) dt,

Convergence analysis of machine learning algorithms for the numerical solution of mean field control and games I: The ergodic case

R Carmona, M Laurière - SIAM Journal on Numerical Analysis, 2021 - SIAM
We propose two algorithms for the solution of the optimal control of ergodic McKean--Vlasov
