Wen, Xian Zhang et Wang, Zhi Cheng, Persistence and Extinction in Two Species Models with Impulse, Acta mathematica Sinica. English series (Print) , 22(2), 2006, pp. 447-454
Both uniform persistence and global extinction are established for a two species predatorprey and competition system with impulse by appealing to theories of abstract persistence, asymptotically autonomous semiflows, and the comparison theorem.
