Abstract: 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,0) is acquired by treating d as a bifurcation parameter. Some sufficient conditions for the existence of positive solution are given.

Key words: predator-prey model, global bifurcation, steady-state solution, bifurcation theory, spectral analysis
