On Weak Solutions to First-Order Discount Mean Field Games
Keywords:
Mean field games, ergodic problem, vanishing discount approximation.Abstract
We establish the existence and uniqueness of weak solutions to first-order discount mean field games and a stability result to give the existence for the ergodic problem. We show an example to illustrate the multiplicity of weak solutions to the ergodic problem. With this motivation, we address a selection condition, which is a necessary condition that any limit of solutions under subsequence satisfies. As an application, we show a nontrivial example to get the convergence of weak solutions.
