讨论了一类在捕食者种群中带有传染病结构的捕食-食饵模型,确定了各平衡点存在的阈值条件.此外,利用特征根法、Hurwitz判别法和Lyapunov-Lassel不变集等方法,得到了各个平衡点稳定性的结论.
英文摘要：
An epidemic model of a predator-prey system with epidemic in predator was discussed in this paper, the conditions and threshold to the existence of various equilibriums were established. By means of the characteristic root method, Hurwitz criterion and Lyapunov-Lassel invariant set theorem, the stable results of various equilibriums were obtained.
