Positive Solution for a Diffusive Three-species Predator-prey Model
In this paper, we study a diffusive threespecies predator-prey model with Beddington-DeAngelis functional response under Robin boundary condition. Some sufficient and necessary conditions for the existence and nonexistence of positive solution are obtained mainly using the fixed point index theory. The results of existence for positive solution indicate diffusion and functional response does help to create stationary pattern.
