通过讨论一类离散神经网络模型,利用数学分析技巧,对线性化系统的特征根进行分析,获得了平衡点的局部稳定性及分支点,并利用规范型理论和中心流形理论得出了分支方向和稳定性的计算公式.
In this paper, we consider a discrete neural network model. By using the skill of mathematical analysis, we analysis the characteristic roots of corresponding linearization system and obtain local stability of the equilibrium point and bifurcation point. The calculating formula of direction and stability of the bifurcation are obtained by using the normal form theory and the center manifold theorem.
