Abstract

Mean Field Games provide a powerful framework to analyze the dynamics of a large number of controlled agents in interaction. Here we consider such systems when the interactions between agents result in a negative coordination and analyze the behavior of the associated system of coupled PDEs using the now well established correspondence with the non linear Schr\"odinger equation. We focus on the long optimization time limit and on configurations such that the game we consider goes through different regimes in which the relative importance of disorder, interactions between agents and external potential varies, which makes possible to get insights on the role of the forward-backward structure of the Mean Field Game equations in relation with the way these various regimes are connected.

Strengths

1) Well performed and interesting, on a topical subject
2) Well written, review like paper on a trans-disciplinary subject

Weaknesses

1) Method seems restricted to the very special case of quadratic games
2) Quite technical paper

Report

I suggest acceptance of this paper essentially as it

Requested changes

Maybe discuss if and how these methods can be adapted to more general cases: non quadratic games; time dependent potential U_0.
