报告题目：Bifurcation analysis of predator-prey system with fear effect and prey refuge
报告摘要：In this talk, we consider a Beddington-DeAngelis predator -prey model with fear effect and refuge. For a multiple delayed predator-prey system with fear effect, prey refuge and Crowley-Martin function, we discuss the stability switching properties of such system whose coefficient depends on the delay by extending the crossing curve methods. For a Beddington-DeAngelis predator-prey model with fear effect and refuge, we obtain various of bifurcations, which include not only different bifurcations of co-dimension one, such as, saddle-node bifurcation, transcritical bifurcation and Hopf bifurcation, but also bifurcation of co-dimensional two---Bogdanov-Taken bifurcation. We also design a hybrid control strategy to control Hopf bifurcation according to the state feedback control method. Finally, some numerical simulations are carried out to confirm our theoretical results. This is a joint work with Ziwei Liang and Jiaoguo Wang.
