The General Non-Abelian Kuramoto Model on the 3-sphere.

We introduce non-Abelian Kuramoto model on S3 in the most general form. Following an analogy with the classical Kuramoto model (on the circle S1), we study some interesting variations of the model on S3 that are obtained for particular coupling functions. As a partial case, by choosing "standard" coupling function one obtains a previously known model, that is referred to as Kuramoto-Lohe model on S3.We briefly address two particular models: Kuramoto models on S3 with frustration and with external forcing. These models on higher dimensional manifolds have not been studied so far. By choosing suitable values of parameters we observe different nontrivial dynamical regimes even in the simplest setup of globally coupled homogeneous population.Although non-Abelian Kuramoto models can be introduced on various symmetric spaces, we restrict our analysis to the case when underlying manifold is the 3-sphere. Due to geometric and algebraic properties of this specific manifold, variations of this model are meaningful and geometrically well justified. [ABSTRACT FROM AUTHOR]
