Closed-loop convergence for mean field games with common noise

D Lacker, L Le Flem - The Annals of Applied Probability, 2023 - projecteuclid.org
This paper studies the convergence problem for mean field games with common noise. We
define a suitable notion of weak mean field equilibria, which we prove captures all …

Mean field game master equations with anti-monotonicity conditions

C Mou, J Zhang - Journal of the European Mathematical Society, 2024 - ems.press
It is well known that the monotonicity condition, either in Lasry–Lions sense or in
displacement sense, is crucial for the global well-posedness of mean field game master …

Monotone solutions for mean field games master equations: finite state space and optimal stopping

C Bertucci - Journal de l'Ecole polytechnique—Mathématiques, 2021 - numdam.org
We present a new notion of solution for mean field games master equations. This notion
allows us to work with solutions which are merely continuous. We first prove results of …

Wellposedness of second order master equations for mean field games with nonsmooth data

C Mou, J Zhang - arXiv preprint arXiv:1903.09907, 2019 - arxiv.org
In this paper we study second order master equations arising from mean field games with
common noise over arbitrary time duration. A classical solution typically requires the …

Large population games with interactions through controls and common noise: convergence results and equivalence between open-loop and closed-loop controls

In the presence of a common noise, we study the convergence problems in mean field game
(MFG) and mean field control (MFC) problem where the cost function and the state dynamics …

A unifying framework for submodular mean field games

J Dianetti, G Ferrari, M Fischer… - … of Operations Research, 2023 - pubsonline.informs.org

sufficient conditions that allow us to prove the existence and approximation of strong mean …

Propagation of chaos of forward–backward stochastic differential equations with graphon interactions

E Bayraktar, R Wu, X Zhang - Applied Mathematics & Optimization, 2023 - Springer

Forcing finite state mean field games by a relevant form of common noise is a subtle issue,
which has been addressed only recently. Among others, one possible way is to subject the …

Selection by vanishing common noise for potential finite state mean field games

A Cecchin, F Delarue - Communications in Partial Differential …, 2022 - Taylor & Francis
The goal of this paper is to provide a selection principle for potential mean field games on a
finite state space and, in this respect, to show that equilibria that do not minimize the …
