Abstract:

This paper is concerned with a diffusive three-species predator-prey model
subject to the homogeneous Dirichlet boundary condition. Using the local and global bifurcation theory, the existence, mniqueness, stability and multiplicity of positive solutions are obtained.

Key words: Predator-prey model positive solutions, Bifurcation, uniqueness, Stability,
Multiplicity
