Simplest normal forms of generalized Neimark-Sacker bifurcation

Transactions of Tianjin University, 2009
The normal forms of generalized Neimark-Sacker bifurcation are extensively studied using normal form theory of dynamic system. It is well known that if the normal forms of the generalized Neimark-Sacker bifurcation are expressed in polar coordinates, then all odd order terms must, in general, remain in the normal forms. In this paper, five theorems are

Neimark‐Sacker bifurcation of a fourth order difference equation

Mathematical Methods in the Applied Sciences, 2018
In this article, we study stability and bifurcation of a fourth order rational difference equation. We give condition for local stability, and we show that the equation undergoes a Neimark‐Sacker bifurcation. Moreover, we consider the direction of the Neimark‐Sacker bifurcation. Finally, we numerically validate our analytical results.

Neimark-Sacker bifurcation and chaos control in Hassell-Varley model

Journal of Difference Equations and Applications, 2017
AbstractWe investigate the complex behaviour of a modified Nicholson–Bailey model. The modification is proposed by Hassel and Varley taking into account that interaction between parasitoids is taken in such a way that the searching area per parasitoid is inversely proportional to the m-th power of the population density of parasitoids.
