Abstract:

In this paper, the periodic LotkaVolterra predatorprey systems are studied. Using the method of persistence theory, integral in mean and differential inequality principle, some necessary and sufficient criteriors for uniform  persistence are established. We obtain some new results.

Key words: Periodic environment, Predatorprey system, Uniform persistence
