报告题目：Bifurcation and control of predator-prey system with fear effect and prey refuge
报告摘要：In this talk, we discuss bifurcations of predator-prey models with fear effect and refuge. For a multiple delayed predator-prey system with 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. By designing a hybrid controller integrating linear time-delayed state feedback and parametric regulation, we also achieve the local asymptotic stability at the positive equilibrium is achieved within the target delay interval. Finally, some numerical simulations are carried out to confirm our theoretical results.This is a joint work with Ziwei Liang and Jiaoguo Wang.
