For the high-dimensional Kuramoto model with identical oscillators under a general digraph that has a directed spanning tree, although exponential synchronization was proved under some initial state constraints, the exact exponential synchronization rate has not been revealed until now. In this paper, the exponential synchronization rate is precisely determined as the smallest non-zero real part of Laplacian eigenvalues of the digraph. Our obtained result extends the existing results from the… 
A Novel Highly Nonlinear Quadratic System: Impulsive Stabilization, Complexity Analysis, and Circuit Designing
This work introduces a three-dimensional, highly nonlinear quadratic oscillator with no linear terms in its equations and reveals that this system’s attractor is self-excited.


On Exponential Synchronization of Kuramoto Oscillators
A lower bound on the coupling gain is derived that is sufficient to guarantee oscillator synchronization and further sufficient conditions are derived to ensure exponential synchronization of the angular frequencies of all oscillators to the mean natural frequency of the group.

Synchronization analysis of Kuramoto oscillators
Abstract. In this paper, we study the original Kuramoto oscillators and the generalized Kuramoto oscillators with directed coupling topology. For the original Kuramoto model with identical
Non-Abelian Kuramoto models and synchronization
We describe non-Abelian generalizations of the Kuramoto model for any classical compact Lie group and identify their main properties. These models may be defined on any complex network where the
Exponential Synchronization Rate of Kuramoto Oscillators in the Presence of a Pacemaker
It is proved that synchronization can be ensured even when the phases are not constrained in an open half-circle, which improves the existing results in the literature.
Complete Entrainment of Lohe Oscillators under Attractive and Repulsive Couplings
It is proved that the state to the Lohe system converges to the ground state with zero order parameter, and it is shown that the order parameter evolves from nonzero values toward the unit value or zero exponentially fast, depending on the nature of the couplings.
