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