Linear quadratic mean-field game-team analysis: a mixed coalition approach

Abstract: Mean-field theory has been extensively explored in decision analysis of {large-scale} (LS) systems but traditionally in pure" cooperative or competitive settings. This leads to the so-called mean-field game (MG) or mean-field team (MT). This paper introduces a new class of LS systems with cooperative inner layer and competitive outer layer, so amixed" mean-field analysis is proposed for distributed game-team strategy. A novel asymptotic mixed-equilibrium-optima is also proposed and verified.
