摘要
利用重合度理论中的延拓定理和微分不等式技巧,给出了具有状态依赖时滞和分布时滞的脉冲细胞神经网络的周期解的存在性的充分条件.
By using the continuation theorem of Mawhin＇s coincidence degree theory and differential inequality artifice.sufficient conditions are obtained for the existence of periodic solution for cellular neural networks with distributed delays and state-dependent delays and impulses.
