In this article, a novel discrete system based on an economic model is introduced. Conditions for local stability of the model’s fixed points are obtained. Existence of supercritical Neimark–Sacker bifurcation is shown around the game’s Nash equilibrium. Existence of stable period-2 orbits resulting from flip bifurcation around the game’s Nash equilibrium is also proved. Existence of chaotic dynamics in the proposed game is also shown via two routes: Neimark–Sacker bifurcation and flip bifurcation. Based on the bifurcation theory of discrete-time systems, sufficient conditions of transcritical bifurcation are derived and applied to the proposed model. The interesting phenomenon of coexisting multi-chaotic attractors, such as coexistence of two, three, four, and five-piece chaotic attractors, is found in the proposed model. For this reason, numerical simulations of basins of attraction are performed to verify the appearance of …
This paper introduces an attempt to investigate the complex dynamics of a nonlinear duopoly game of players (firms) adopting prices as their decision variables. Two different models are introduced…
In this paper, we give a proper investigation of the problem of remanufacturing duopoly game. A smooth piecewise map is introduced to describe such game. A rich analysis either analytical or…
Memory effects play a critical role in complex immune systems. In this paper, the recent efficient and realistic Atangana–Baleanu fractional order derivative, with non-local and non-singular…
