On the stability of discrete-time dynamic oligopoly games

Dynamic oligopoly games are examined with discrete time scales. The authors described the global asymptotical stability of the equilibrium points of the games. Both the basic model and those cases are examined, when players may change their strategies only in a restricted way or when they have to reckon with the cost of change of strategies. Finally a special sequential model is examined when (in a certain sequence) in every period there is only one player changing his/her strategy.
