Query: Ott-Antonsen reduction for the non-Abelian Kuramoto model on the
  3-sphere   We are interested in low-dimensional dynamics in an ensemble of coupled
nonidentical generalized oscillators on the 3-sphere. The system of governing
equations for such an ensemble is referred to as non-Abelian Kuramoto model in
the literature. We establish an analogue (or an extension) of the Ott-Antonsen
(OA) result for this model.
