Abstract:
In this paper, we study the following nonautonomous rational difference equation\[y_{n+۱}=\frac{\alpha_n+y_n}{\alpha_n+y_{n-k}},\quad n=۰,۱,...,\]where \left\{\alpha_n\right\}_{n\geq۰} is a bounded sequence of positive numbers, k is a positive integer and the initial values y_{-k},...,y_۰ are positive real numbers. We give sufficient conditions under which the unique equilibrium \bar{y}=۱ is globally asymptotically stable. Furthermore, we establish an oscillation result for positive solutions about the equilibrium point. Our work generalizes and improves earlier results in the literature.
