Global stability analysis of impulsive Cohen-Grossberg neural networks with delay

In this Letter, several classes of impulsive Cohen-Grossberg neural networks with time delay are studied. Globally exponential stability and globally exponentially robust stability are investigated by Lyapunov function and Halanay inequality. Furthermore, sufficient conditions are given to guarantee the existence of ω-periodic solution and all other solutions are convergent to it globally exponentially. At last, two examples are given to show the effectiveness of results in this Letter.
