本文利用Banach空间中不动点原理和Lyapunov理论,研究一类变时滞神经网络系统概周期解的存在性和全局渐近稳定性,推广和改进了已有文献的结论.
Based on fixed points principle and the Lyapunov theory,a kind of neural network systems with delays is discussed.Some new criteria ensuring existence and uniqueness of an almost periodic solution and global asymptotical stability are presented.Some obtained results are extended and improved.
