摘要
主要研究分数阶时滞Cohen-Grossberg型BAM神经网络的有界性和周期性问题.利用分数阶微积分性质,借助于微分中值定理和Ascoli-Arzela定理,给出了判定系统解的有界性,S-渐近ω-周期和全局渐近ω-周期解的充分条件.最后通过数值模拟例子验证所得到理论结果的有效性.
This paper mainly studies the boundedness and periodicity of fractional Cohen Grossberg type BAM neural network with delay.By using the properties of fractional calculus,differential mean value theorem and Ascoli-Arzela theorem,the sufficient conditions for determining the boundedness of system solution and global S-asymptoticωperiodic solution are given.Finally,the validity of the theoretical results is verified by numerical simulation examples.
