摘要 研究了一类具有时滞的三维神经网络模型的分支与稳定性.通过对该模型的特征根的分析,获得了平衡点的稳定性和Hopf分支的存在性.最后利用规范型方法和中心流形理论,得到了Hopf分支的分支周期解的稳定性和分支的方向. This paper studies the branches and stability of a three-dimensional neural network model with time delay.Based on an analysis of the model eigenvalue,the paper proves the equilibrium stability and the existence of Hopf bifurcation.
