A Bertrand Duopoly Game with Long-Memory Effects

الملخص EN

Reconsidering the Bertrand duopoly game based on the concept of long short-term memory, we construct a fractional-order Bertrand duopoly game by extending the integer-order game to its corresponding fractional-order form.

We build such a Bertrand duopoly game, in which both players can make their decisions with long-memory effects.

Then, we investigate its Nash equilibria, local stability, and numerical solutions.

Using the bifurcation diagram, the phase portrait, time series, and the 0-1 test for chaos, we numerically validate these results and illustrate its complex phenomena, such as bifurcation and chaos.
