The discrete Rosenzweig model. (English) Zbl 0694.92014
Summary: Discrete time versions of the Rosenzweig predator-prey model [see {\it M. L. Rosenzweig}, Science 171, 385-387 (1971)] are studied by analytic and numerical methods. The interaction of the Hopf bifurcation leading to periodic orbits and the period-doubling bifurcation are investigated. It is shown that for certain choices of the parameters there is stable coexistence of both species together with a local attractor at which the prey is absent.
