Abstract:Abstract:Taking into account stage-structure for prey and periodic pulse at different fixed moments, a delayed prey-predator system with Beddington-type functional response was investigated. Applying the small amplitude perturbation method and Floquet's theory, we obtained the sufficient conditions for the local stability, globally asymptotical stability and global attractivity of the prey-extinction periodic solution. Further, by using theories of impulsive differential equation and delay differential equatio… Show more
