Stability and Hopf bifurcation analysis for a financial dynamical model with time delay
Dr. Kübra Değerli
Bahçeşehir University, İstanbul, Türkiye
Abstract: In this talk, the stability and Hopf bifurcation of a fractional-order delayed financial system will be discussed. In the analysis, the Laplace transform is used after the nonlinear system is converted to a linear system. By considering the time delay τ as the bifurcation parameter, it is shown that the equilibrium point remains asymptotically stable for all τ less than τ_0, whereas for τ greater than τ_0, the system undergoes a Hopf bifurcation at certain critical values of the delay. Finally, all theoretical results are supported by numerical simulations using MATLAB.
