On the Dynamics of a Discrete Fractional-Order Cournot-Bertrand Competition Duopoly Game

A discreet fractional-order Cournot-Bertrand competition duopoly game is introduced based on the fractional-order difference calculus of the Caputo operator. The model is designed when players can make long memory decisions. The local stability of equilibrium points is discussed for the proposed model. Some numerical simulations explore the model's bifurcation and chaos by employing bifurcation diagrams, phase portraits, maximal Lyapunov exponents, and time series. According to our findings, the fractional-order parameter has an effect on the game's stability and dynamics.
