摘要
对一类带有时滞的肿瘤-免疫模型,研究了其稳定性与Hopf分岔.首先给出了该模型解的非负有界性,然后讨论了无肿瘤平衡点和正平衡点的存在性,再研究了平衡点的局部稳定性以及Hopf分岔现象,最后利用数值模拟验证了理论分析的结果.
We study the stability and Hopf bifurcation for a tumor-immune model with time delay.The existence of tumor-free equilibrium points and positive equilibrium points is discussed.The local stability of the equilibrium points and Hopf bifurcation phenomenon are studied.Finally,the results of theoretical analysis are verified by numerical simulations.
