This paper investigates the periodic solutions for a class of stochastic neural networks with time-varying delays, establishing sufficient conditions on the existence and exponential stability of periodic solution using fixed points principle and Gronwall-Bellman inequality. The theoretical results are validated through a numerical example, showing applicability to the corresponding deterministic systems.
This paper is concerned with the periodic solutions for a class of stochastic Cohen-Grossberg neural networks with time-varying delays. Since there is a nonlinearity in the leakage terms of stochastic Cohen-Grossberg neural networks, some techniques are needed to overcome the difficulty in dealing with the nonlinearity. By applying fixed points principle and Gronwall- Bellman inequality, some sufficient conditions on the existence and exponential stability of periodic solution for the stochastic neural networks are established. Moreover, a numerical example is presented to validate the theoretical results. Our results are also applicable to the existence and exponential stability of periodic solution for the corresponding deterministic systems.
