Analysis of a Periodic Impulsive Predator-Prey System with Disease in the Prey

Abstract EN

We investigate a periodic predator-prey system subject to impulsive perturbations, in which a disease can be transmitted among the prey species only, in this paper.

With the help of the theory of impulsive differential equations and Lyapunov functional method, sufficient conditions for the permanence, global attractivity, and partial extinction of system are established, respectively.

It is shown that impulsive perturbations contribute to the above dynamics of the system.

Numerical simulations are presented to substantiate the analytical results.
