Existence and exponential stability of almost periodic solutions for cellular neural networks without global Lipschitz conditions

Abstract

In this paper cellular neutral networks with time-varying delays and continuously distributed delays are considered. Without assuming the global Lipschitz conditions of activation functions, some sufficient conditions for the existence and exponential stability of the almost periodic solutions are established by using the fixed point theorem and differential inequality techniques. The results of this paper are new and complement previously known results.

Keywords: cellular neural networks, almost periodic solution, exponential stability, fixed point theorem, delays
