Characteristics of two coupled oscillators () in the deterministic case () close to and .

<p>(A) A fragment of the bifurcation diagram. Here and in the following charts, the black lines stand for the in-phase oscillations, red for the anti-phase and blue for the asymmetric oscillations. Solid lines correspond to stable solutions, dashed lines for unstable, and dash-dotted line indicates the unstable focus. (B) Phase portrait for the multystability region at . Parameters: , .
