[HTML][HTML] On the optimal rate for the convergence problem in mean field control

S Daudin, F Delarue, J Jackson - Journal of Functional Analysis, 2024 - Elsevier
The goal of this work is to obtain (nearly) optimal rates for the convergence problem in mean
field control. Our analysis covers cases where the solutions to the limiting problem may not …

Approximately optimal distributed stochastic controls beyond the mean field setting

J Jackson, D Lacker - arXiv preprint arXiv:2301.02901, 2023 - arxiv.org

identical interest stochastic dynamic games) with large or countably infinite numbers of …

From finite population optimal stopping to mean field optimal stopping

M Talbi, N Touzi, J Zhang - The Annals of Applied Probability, 2024 - projecteuclid.org
This paper analyzes the convergence of the finite population optimal stopping problem
towards the corresponding mean field limit. Building on the viscosity solution …

Sharp convergence rates for mean field control in the region of strong regularity

P Cardaliaguet, J Jackson… - arXiv preprint arXiv …, 2023 - arxiv.org
We study the convergence problem for mean field control, also known as optimal control of
McKean-Vlasov dynamics. We assume that the data is smooth but not convex, and thus the …
