摘要
利用分歧理论和谱分析的方法研究了一类捕食-食饵模型平衡解的整体分歧,得到了在以d为分歧参数的条件下,系统在半平凡解(θ0)附近出现分歧现象,得到了该模型正解存在的充分条件。
The global bifurcation of a positive steady-state solution for a kind of predator-prey model is investigated by the methods of spectral analysis and bifurcation theory. The bifurcation at the positive steady-state solution（θ, O） is acquired by treating d as a bifurcation parameter. Some sufficient conditions for the existence of positive solution are given.
