Existence and exponential stability of almost periodic solutions for CNNs with time-varying leakage delays

This paper presents a new generalized cellular neural network model with time-varying delays in leakage (or forgetting) terms. By using Lyapunov functional method and differential inequality techniques, we obtain some sufficient conditions ensuring the existence and exponential stability of almost periodic solutions for the considered model. Our results complement with some recent ones. Moreover, an illustrative example is given to demonstrate the effectiveness of the obtained results.
