On periodic solutions of a discrete Nicholson’s dual system with density-dependent mortality and harvesting terms
Abstract In this study, we discuss the existence of positive periodic solutions of a class of discrete density-dependent mortal Nicholson’s dual system with harvesting terms. By means of the continuation coincidence degree theorem, a set of sufficient conditions, which ensure that there exists at le...
