As a rule, ensembles with identical oscillators and symmetric couplings are gradient flows (sometimes in more than one sense). Underline that models on spheres, as well as on special orthogonal and unitary groups are gradient flows in the chordal metric on these manifolds [87]. On spheres, this is equivalent to the cosine metric. Consensus algorithms on Grassmannian manifolds are gradient flows as well, we refer to [7] for an explanation. The above observations further imply that by adding the noise in an appropriate way to the above systems we obtain various Langevin dynamics. For instance, (1) are Langevin dynamics for the potential As already noted above, recent geometric investigations of Kuramoto models have shown that models on spheres (12) with global coupling induce gradient flows in hyperbolic balls [76]. In general, the question of hyperbolic gradient flows induced by Kuramoto models on spheres is still to be fully explored. In particular, it is interesting to examine conditions for the potential dynamics on hyperbolic multi-discs and multi-balls which are induced by the models with several sub-ensembles. The second interesting question is adding the noise in an appropriate way in order to obtain Langevin dynamics on hyperbolic balls. Author:
