Global exponential stability of Hopfield reaction-diffusion neural networks with time-varying delays

摘要

The authors analyze the existence of the equilibrium point and global exponential stability for Hopfieid reaction-diffusion neural networks with time-varying delays by means of the topological degree theory and generalized Halanay inequality. Since the diffusion phenomena and time delay could not be ignored in neural networks and electric circuits, the model presented here is close to the actual systems, and the sufficient conditions on global exponential stability established in this paper, which are easily verifiable, have a wider adaptive range.
