Remarks on a diffusive predator-prey model with Beddington-DeAngelis functional response

摘要：

In this paper, a diffusive ratio-dependent predator-prey model with Beddington-DeAngelis functional response is revisited. By the comparison argument and iteration technique, some improved a priori estimates for positive solutions are given. Thus we derive some further results for this model, that is, we discuss the global stability of the unique constant positive steady state and, obtain some improved nonexistence results for non-constant positive steady states.
