朝代循环模型的分支方向及稳定性
The Hopf Bifurcation's Direction and Stability of the Dynastic Cycle Model
-
摘要: 对于具有时滞的朝代循环模型,当时间延迟到达或穿过临界值时,系统在正平衡点附近出现了一族周期解。应用规范型和中心流形理论给出决定该模型分支方向及分支周期解稳定性的显示表达式。Abstract: The positive equilibrium's stability changes when the delay arrives at or crosses a sequence of critical values in the dynamical model of the dynastic cycle with delay .Employing the normal form theory and the center manifold argument in this paper ,we give the explicit formulas that determine the direction and other properties of bifurcation periodic solutions .
