Summary:
The time-delay connection induced amplitude death has been extensively investigated in the field of nonlinear science. Our previous study showed that a time-varying delay connection can induce a stabilization of unstable steady states in a pair of oscillators. This report extends our previous study to network oscillators. A linear stability analysis reveals that such connection is valid even for network oscillators. The analytical results are verified by numerical simulations.
