Abstract

We investigate global dynamics of the equation

$$\begin{aligned} x_{n+1}=\frac{x_{n-1}}{ax_{n}^{2}+ex_{n-1}+f},\quad n=0,1,2,\ldots , \end{aligned}$$

where the parameters ae and f are nonnegative numbers with condition \(a+e+f>0\) and the initial conditions \(x_{-1},x_{0}\) are arbitrary nonnegative numbers such that \(x_{-1}+x_{0}>0\). The global dynamics of this equation consists of three bifurcations, two exchange of stability bifurcations and one global period doubling bifurcation.
