Global behavior of solutions to two classes of second-order rational difference equations. (English) Zbl 1177.39016
Summary: For nonnegative real numbers $$\alpha,\beta,\gamma, A, B$$, and $$C$$ such that $$B+C>0$$ and $$\alpha+\beta+\gamma>0$$, the difference equation $x_{n+1}=\frac{\alpha+\beta x_n+\gamma x_{n-1}}{A+Bx_n+Cx_{n-1}},\quad n=0,1,2,\dots$
has a unique positive equilibrium. A proof is given here for the following statements: (1) For every choice of positive parameters $$\alpha,\beta,\gamma, A, B$$, and $$C$$, all solutions to the difference equation
$x_{n+1}=\frac{\alpha+\beta x_n+\gamma x_{n-1}}{A+B x_n+Cx_{n-1}},\quad n=0,1,2,\dots,x-1,\;x_0\in [0,\infty)$
converge to the positive equilibrium or to a prime period-two solution. (2) For every choice of positive parameters $$\alpha,\beta,\gamma$$, $$B$$, and $$C$$, all solutions to the difference equation
$x_{n+1}=\frac{\alpha+\beta x_n+\gamma x_{n-1}}{B x_n+C x_{n-1}}, \quad n=0,1,2,\dots,x_{-1},\;x_0\in(0,\infty)$
converge to the positive equilibrium or to a prime period-two solution.
