Local synchronization of one-to-one coupled neural networks with discontinuous activations

Abstract

In this paper, local synchronization is considered for coupled delayed neural networks with discontinuous activation functions. Under the framework of Filippov solution and in the sense of generalized derivative, a novel sufficient condition is obtained to ensure the synchronization based on the Lyapunov exponent and the detailed analysis in Danca (Int J Bifurcat Chaos 12(8):1813-1826, 2002; Chaos Solitons Fractals 22:605-612, 2004). Simulation results are given to illustrate the theoretical results.
