NEIMARK-SACKER BIFURCATION ON AN ECOLOGICAL MODEL
Abstract
In this paper a two dimensional ecological model is taken whose Neimark-Sacker bifurcation behavior has been analyzed. Existence of Neimark-Sacker bifurcation is confirmed for infinite values of the control parameters and a suitable procedure has been adopted to obtain the control parameter for which Neimark-Sacker bifurcation occurs. Further the normal form of the model has been obtained to analyze the direction of the Neimark-Sacker bifurcation.
Key Words: Neimark-Sacker bifurcation/ fixed points/Periodic orbits/Normal form/Super Critical/Sub Critical.
