Abstract

We give the character of solutions of the following second-order rational difference equation with quadratic denominator

$$\begin{aligned} x_{n+1}=\dfrac{\alpha + \beta x_{n}}{Bx_n + Dx_nx_{n-1} + x_{n-1}}, \end{aligned}$$

where the coefficients are positive numbers, and the initial conditions \(x_{-1}\) and \(x_0\) are nonnegative such that the denominator is nonzero. In particular, we show that the unique positive equilibrium is locally asymptotically stable, and we give conditions on the coefficients for which the unique positive equilibrium is globally stable.
