Query: Synchronization of forced reactively coupled van der Pol oscilators   Synchronization of forced reactively coupled van der Pol oscillators is
investigated in the phase approximation. We discuss essential features of the
reactive coupling. Bifurcation mechanisms for the destruction of complete
synchronization and possible quasi-periodic regimes of different types are
revealed. Regimes when autonomous oscillators demonstrate frequency locking and
beating regimes with incommensurate frequencies are considered and compared.
