Positive solutions of a diffusive predator-prey mutualist model with cross-diffusion

Jun Zhou


In this paper, a competitor-competitor-mutualist model with cross-diffusion is studied by means of Leray-Schauder degree theory and global bifurcation theory. The conditions for the existence and multiplicity of positive solutions are established.
