Periodic solutions of a single species discrete population model with periodic harvest/stock. (English) Zbl 0970.92019
Summary: We discuss a discrete population model describing single species growth with periodic harvest/stock. The theory of coincidence degree is applied to show that the model equation admits two periodic solutions. Under minor technical assumptions, we show that one of these two periodic solutions is positive and attracts almost all positive solutions.
