Abstract:
We study discounted infinite-time mean field games, for which a Nash equilibrium is constructed using the stochastic maximum principle and infinite-time McKean-Vlasov forward-backward stochastic differential equations. We then prove that, at the Nash equilibrium, the value function of the representative player provides a viscosity solution to the corresponding elliptic master equation. Furthermore, we establish the uniqueness of classical solutions to the elliptic master equation under displacement monotonicity and certain growth assumptions. This talk is based on a joint paper with Zeyu Yang.
