摘要
讨论了一类具病毒感染的肿瘤免疫时滞模型,运用时滞微分方程理论分析了模型平衡点的稳定性,得到了hopf分支存在的条件。数值模拟支持了理论分析结果。
This article concerns a class of tumor-immune model of virus infection with delay.The stability of the equilibrium point of the model is analyzed by using the time-delay differential equation theory,and the conditions for the existence of hopf bifurcation are obtained.The numerical simulation supports the theoretical analysis results.
