Average condition for Nonpersistence of a Delayed Discrete Ratio-Dependent Predator-Prey System
Verifiable criteria are established for the nonpersistence for a delayed discrete periodic predator prey model with Holling type Ⅱ functional response.Our investigation shows that the average condition is a sufficient condition for the nonpersistence of the system,this also illuminates that if we study periodic system and its average system (defined in this paper) simultaneously,we can get more recipient results.
