讨论了一类带分布时滞的双向联想记忆神经网络周期解的存在性.通过运用Mawhin迭合度连续性定理,和一些不等式的分析技巧,得到了一些保证周期解存在的充分条件.
The paper is concerned with the existence of periodic solutions for a class of bidirectional associative memory neural networks with distributed delays.By using the Mawhin's continuation theorem for coincidence degree and some inequality analysis techniques,some sufficient conditions are obtained for the existence of periodic solution.
