摘要 一类含分布时滞的随机Hopfield神经网络的稳定性被研究.通过构造恰当的Lyapunov泛函,利用分析技巧并借助非负半鞍收敛定理,该系统平凡解均方指数稳定和几乎必然指数稳定的充分条件被建立.通过一个例子,阐明文中结果的有效性. In this paper, stability of stochastic Hopfield neural network with distributed delay was discussed. By constructing suitable Lyapunov functional and using analysis techniques and semi-martingale convergence theorem, a new sufficient condition to guarantee the mean square exponential stability and almost sure exponential stability for the system was presented. One example was given to show the applicability of the proposed approach.
