Mean-field games with multiple populations of the players have only been studied in the literature in the continuous-time setting. The main results of this article are the first stationary and Markov mean-field equilibrium existence theorems for discrete-time mean-field games of this type. We consider two payoff criteria: discounted payoff and total payoff. The results are provided under some rather general assumptions on one-step reward functions and individual transition kernels of the players. In addition, the results for total payoff case, when applied to a single population, extend the theory of mean-field games also by relaxing some strong assumptions used in the existing literature.", "revisions": [ { "version": "v1", "updated": "2023-04-06T11:13:56.000Z" } ], "analyses": { "subjects": [ "91A15", "91A13", "91A10" ], "keywords": [ "multiple-population discrete-time mean field games", "total payoff", "mean-field equilibrium existence theorems", "discrete-time mean-field game" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
