摘要
研究了一类具有时滞依赖的生态-流行病模型,分析了系统正解的边界和平衡点的稳定性,应用稳定性切换标准讨论了正平衡点的稳定性切换.数值模拟揭示了系统的稳定性切换现象和周期振动,讨论了参数对系统的不稳定性区域的影响.
This paper considers an eco-epidemiological model with delay-dependent. The boundedness of solutions and stability of the equilibrium paints are investigated. By using stability switch criteria studying the stability switch of the positive equihbrium, numerical simulations show stability switch and periodic oscillation. Parameters a.ecting the instability regions of the system are discussed.
