چکیده
|
In this paper, the local stability of the endemic equilibrium and existence of a hopf bifurcation in a susceptible-exposed-infected-recovered (seir) delayed mathematical model for covid-19 pandemic are investigated. by using time-delay as a bifurcation parameter, the associated characteristic equation is analyzed to reveal dynamics of the model. finally, numerical simulations are performed with suitable parameters choice to illustrate the theoretical results of the model.
