Synchronization of Heterogeneous Kuramoto Oscillators with Arbitrary Topology [PDF]

open access: yes, 2014
We study synchronization of coupled Kuramoto oscillators with heterogeneous inherent frequencies and general underlying connectivity. We provide conditions on the coupling strength and the initial phases which guarantee the existence of a Positively ...
