Abstract: |
In this paper, we consider a discrete time logistic competition model. The topological types of flxed points and non-hyperbolic cases are given in order to investigate bifurcations. By applying the center manifold reduction theorem we prove that transcritical bifurcation occurs at three flxed points and stable 2-periodic orbits arise through flip bifurcation which happens at two flxed points. |
