Oscillatory Behavior in a System of Four Coupled Oscillators Model
In this paper, we discuss a system of four coupled oscillators with delays. Some sufficient conditions to guarantee the existence of oscillations for the model are obtained. Computer simulations are provided to demonstrate the present results.
