该文研究一类简化的n个神经元时滞BAM神经网络模型的振动性.利用Chafee的结论,可以证明一类简化的n个神经元时滞BAM神经网络有唯一平衡点且不稳定.这种特殊类型的不稳定性,结合系统所有解的有界性会迫使网络产生永久振动.得出此种振动行为产生的两个充分条件,典型的数值仿真证明了理论结论的正确性.
In this paper, the existence of oscillations for a simplified n-neuron BAM neural network with time delays between neural interconnections is investigated. By using the Chafee's criterion, we prove that a simplified n-neuron BAM neural network has a unique equilibrium point which is unstable. This particular type of instability, combined with the boundedness of the solutions of the system, forces the network to generate a permanent oscillation. Two sufficient conditions for these oscillations are obtained. Typical simulation examples are presented.
