| Abstract: | This paper considers a competing system consisting of two species, one of which can diffuse among n-patches,while the other is confined to one patch and cannot diffuse. It is proved that if the coefficients satisfy certain inequalities, then the system can be made persistent and have a strictly positive periodic orbit which is globally asymptotically stable. |
