Disorder can eliminate oscillator death

We use an array of diffusively coupled limit-cycle oscillators with a regular monotonic trend of natural frequencies to demonstrate that the disorder introduced in the form of random deviations from a linear trend of frequencies can weaken considerably desynchronization-induced oscillator death and, as a result, increase oscillation intensity substantially. There exist definite optimal levels of magnitude of spatial disorder at which maximal oscillatory energy is attained in the array.
