Chaos in cross-coupled BVP oscillators

In this paper, we investigate the cross-coupled BVP oscillators. A single BVP oscillator has two terminals which can extract an independent state variable, so in the preceding works, several coupling systems have studied. Synchronization modes and chaos in these systems are classified as results of bifurcation problems. We revisit one of coupled oscillator, and clarified new results which have not been reported before, i.e., stable tori and its breakdown, and chaotic motions. Also classification of synchronized periodic solutions is done by a bifurcation diagram.
