Abstract: | In this paper, we investigate a diffusive predator-prey model with
fear effect. It is shown that, for the linear predator functional response case,the positive constant steady state is globally asymptotically stable if it ex-ists. On the other hand, for the Holling type II predator functional response
case, it is proved that there exist no nonconstant positive steady states for
large conversion rate. Our results limit the parameters range where complex
spatiotemporal pattern formation can occur. |
