Linear Quadratic Mean Field Games: Decentralized O(1/N)-Nash Equilibria

نویسندگان

چکیده

This paper studies an asymptotic solvability problem for linear quadratic (LQ) mean field games with controlled diffusions and indefinite weights the state control in costs. The authors employ a rescaling approach to derive low dimensional Riccati ordinary differential equation (ODE) system, which characterizes necessary sufficient condition solvability. technique is further used performance estimates, establishing O(1/N)-Nash equilibrium obtained decentralized strategies.

Mean field linear quadratic games

This paper studies linear quadratic games with set up costs monotonic on the number of active players, namely, players whose action is non-zero. Such games arise naturally in joint replenishment inventory systems. Building upon a preliminary analysis of the properties of the best response strategies and Nash equilibria for the given game, the main contribution is the study of the same game unde...

Decentralized Convergence to Nash Equilibria in Constrained Mean Field Control

This paper considers decentralized control and optimization methodologies for large populations of systems, consisting of several agents with different individual behaviors, constraints and interests, and affected by the aggregate behavior of the overall population. For such large-scale systems, the theory of “mean field” games and control has been successfully applied in various scientific dis...

Feedback Nash equilibria for linear quadratic descriptor differential games

In this note we consider the non-cooperative linear feedback Nash quadratic differential game with an infinite planning horizon for descriptor systems of index one. The performance function is assumed to be indefinite. We derive both necessary and sufficient conditions under which this game has a Nash equilibrium.

Explicit solutions of some linear-quadratic mean field games

We consider N -person differential games involving linear systems affected by white noise, running cost quadratic in the control and in the displacement of the state from a reference position, and with long-time-average integral cost functional. We solve an associated system of Hamilton-JacobiBellman and Kolmogorov-Fokker-Planck equations and find explicit Nash equilibria in the form of linear ...

Large-Scale Dynamics of Mean-Field Games Driven by Local Nash Equilibria

We introduce a new mean field kinetic model for systems of rational agents interacting in a game-theoretical framework. This model is inspired from noncooperative anonymous games with a continuum of players and Mean-Field Games. The large time behavior of the system is given by a macroscopic closure with a Nash equilibrium serving as the local thermodynamic equilibrium. An application of the pr...
