Abstract

This paper gives sufficient conditions for having complete synchronization of oscillators in connected undirected networks. The considered oscillators are not necessarily identical and the synchronization terms can be nonlinear. An important problem about oscillators networks is to determine conditions for having complete synchronization that is the stability of the synchronous state. The synchronization study requires to take into account the graph topology. In this paper, we extend some results to non linear cases and we give an existence condition of trajectories. Sufficient conditions given in this paper are based on the study of a Lyapunov function and the use of a pseudometric which enables us to link network dynamics and graph theory. Applications of these results are presented.
