The death of quasi-periodic regimes in a system of dissipatively coupled van der Pol oscillators under pulsed drive action

We have studied a system of coupled van der Pol oscillators under pulsed drive action. In the case where the coupled oscillators exhibit the death of oscillations, the introduction of a pulsed drive leads to the appearance of islands corresponding to quasi-periodic regimes in the drive period-amplitude plane, which are also dying with an increase in the frequency detuning.
