%0 Journal Article %T Mean Field Games and Nonlinear Markov Processes %A Vassili N. Kolokoltsov %A Jiajie Li %A Wei Yang %J Mathematics %D 2011 %I arXiv %X In this paper, we investigate the mean field games with $K$ classes of agents who are weakly coupled via the empirical measure. The underlying dynamics of the representative agents is assumed to be a controlled nonlinear Markov process associated with rather general integro-differential generators of L\'evy-Khintchine type (with variable coefficients). We show that nonlinear measure-valued kinetic equations describing the dynamic law of large numbers limit for system with large number N of agents are solvable and that their solutions represent 1/N-Nash equilibria for approximating systems of N agents. %U http://arxiv.org/abs/1112.3744v2
