| Abstract: | In this paper,two-species nonautonomous impulsive systems that arise in plankton allelopathy with time delays and periodic environmental factors are considered.By means of coincidence degree theory and some analysis techniques,we obtain some new results on the existence of positive periodic solutions to the system.Our results generalize and improve the related results. |
