Abstract. In this paper, we present a mathematical model of COVID-19 transmission dynamics and control strategies. The result reveal that the disease free equilibrium point exists and it is locally and globally asymptotically stable when the reproduction number is less than one unit and otherwise unstable when is greater than one unit.

A friction model that captures this stiction phenomenon that you may be familiar with is the Coulomb friction model (the friction has constant magnitude and opposes the direction of motion). Whereas viscous friction causes the amplitude to decay exponentially, Coulomb friction causes the amplitude to decay linearly (you can prove this to yourself).
