Abstract

We investigate the global asymptotic stability and Naimark-Sacker bifurcation of the difference equation \[x_{n+1} =\frac{F}{bx_nx_{n-1} + cx^2_{n-1} + f} , n = 0, 1, ... ,\] with non-negative parameters and nonnegative initial conditions \(x_{-1}, x_0\) such that \(bx_0x_{-1} + cx^2_{-1} + f > 0\). By using fixed point theorem for monotone maps we find the region of parameters where the unique equilibrium is globally asymptotically stable.
