After revision: Populations of nonlinear oscillators are found in a variety of applications from physics, chemistry, biology, and engineering \mbox{%DIFAUXCMD physics,kuramoto,winfree,Keener2009 The collective behavior of biological oscillators has been recognized as an important problem for several decades, but its control has come into limelight only recently. Much of the focus for control has been on desynchronization of an oscillator population, motivated by the pathological neural synchrony present in essential and parkinsonian tremor.
