Analysis of a Periodic Single Species Population Model Involving Constant Impulsive Perturbation

Abstract EN

This is a continuation of the work of Tan et al.

(2012).

In this paper a periodic single species model controlled by constant impulsive perturbation is investigated.

The constant impulse is realized at fixed moments of time.

With the help of the comparison theorem of impulsive differential equations and Lyapunov functions, sufficient conditions for the permanence and global attractivity are established, respectively.

Also, by comparing the above results with corresponding known results of Tan et al.

(2012) (i.e., the above model with linear impulsive perturbations), we find that the two different types of impulsive perturbations have influence on the above dynamics.

Numerical simulations are presented to substantiate our analytical results.
