“…For non-identical oscillators we analysed one particular class of possible equilibrium solutions, showing that its shape can be analytically reconstructed and thus opening new possibilities for more efficient modeling and future analysis of the system. Still, there are many questions that could be investigated in details regarding the system (19), its PDE approximation (21) and the synchronization condition (24). First, Corollary 3 for the general winding number k in the case of identical oscillators gives only sufficient conditions on stability and probably more rigorous statements could be made based on Theorem 2.…”
