研究了一类具有Allee效应的改进的Nicholson苍蝇时滞微分方程的时滞动力学.利用Lyapunov-LaSalle不变性原理研究了多重平衡点的稳定性和吸引域。利用正平衡点附近的局部和全局Hopf分支证明了多周期解的存在性,这些解产生了长的瞬态振荡模式和渐近稳定的振荡模式.
The bistable dynamics of a modified Nicholson's blowflies delay differential equation with Allee effect is analyzed. The stability and basins of attraction of multiple equilibria are studied by using Lyapunov-LaSalle invariance principle. The existence of multiple periodic solutions are shown using local and global Hopf bifurcations near positive equilibria, and these solutions generate long transient oscillatory patterns and asymptotic stable oscillatory patterns.
