Periodic solutions for a delayed predator-prey system with dispersal and impulses. <i>Electronic Journal of Differential Equations, 2005</i>(31), pp. 1-14.1072-6691https://hdl.handle.net/10877/13605A delayed predator-prey system with prey dispersal in n-patch environments and impulse effects is investigated. By using Gaines and Mawhin's continuation theorem of coincidence degree theory, a set of easily verifiable sufficient conditions are derived for the existence of positive periodic solutions to the system.Text14 pages1 file (.pdf)enAttribution 4.0 InternationalPredator-prey systemImpulseDispersionPeriodic solutionsCoincidence degreeArticleThis work is licensed under a Creative Commons Attribution 4.0 International License.
