Existence and global exponential stability of periodic solution of cellular neural networks with time-varying delays. (English) Zbl 1055.34135

The authors investigate a system of cellular neural networks with periodic coefficients and periodic delays, all of them with the same period \(\omega\). Using a topological degree argument, some sufficient conditions for the existence of at least one \(\omega\)-periodic solution of the system are found. Then, additional assumptions are imposed to guarantee that the periodic solution is unique and globally exponentially stable.
