Mathematical Analysis of Fractal-Fractional Mathematical Model of COVID-19

In this work, we modified a dynamical system that addresses COVID-19 infection under fractal-fractional-order derivative. The model investigates the psychological effects of disease on humans. We establish global and local stability results for aforementioned Additionally, compute fundamental reproduction number, which helps predict transmission in community. Using Carlos Castillo-Chavez method, derive some adequate about bifurcation analysis proposed model. also investigate sensitivity to given using criteria Chitnis his co-authors. Furthermore, formulate characterization optimal control strategies by utilizing Pontryagin’s maximum principle. simulate different fractal-fractional orders subject various parameter values Adam Bashforth’s numerical method. All findings are presented graphically.
