Periodic solution to Cohen-Grossberg BAM neural networks with delays on time scales

In this paper, we investigate first the existence and uniqueness of periodic solution in a general Cohen-Grossberg BAM neural networks with delays on time scales by means of contraction mapping principle. Then by using the existence result of periodic solution and constructing a Lyapunov functional, we discuss the global exponential stability of periodic solution for above neural networks. In the last section, we also give examples to demonstrate the validity of our global exponential stability result of the periodic solution for above neural networks.
