通过利用Banach空间中的不动点定理和Lyapunov泛函的方法,获得了具分布时滞的分层抑制细胞神经网络概周期解的存在性的新结论。所获结果在较大程度上改进和推广了已有文献中的相应结果。 By using fixed point theorem and Lyapunov functional in Banach spaces, a new conclusion about the existence of almost periodic solutions of hierarchical inhibitory cellular neural networks with distributed delays is obtained. The results obtained improve and popularize the corresponding results in the existing literature to a large extent.
